Adventure Time: Awakening/Transcript

[Warner Bros. Pictures logo starts and it flashes briefly into Warner Bros. Pictures logo from 1991 then cuts to Finn who has an interview with Flame Princess.]

Finn: I got shown up by Cinnamon Bun. I never realize what I had to do... until there was nothing... I could do something very badly.

[The scene cuts as Sony and Columbia Pictures logos start and it flashes briefly into Columbia Pictures logo from 1991 then cuts back to Finn.]

Finn: When we broke up, I said I was truly sorry. I never understood... what I totally did wrong. [breathes heavily] I know you said I've grown up a lot.

[The scene cuts as Cartoon Network Studios logo starts and it fkashes briefly into the classic Cartoon Network Studios logo then cuts back to Finn.]

Flame Princess: Yes, Finn, I said you've grown up a lot. And yes, I already forgave you.

Finn: [tearfully] That's not what the hell's supposed to happen, you know that?

Flame Princess: Um, yes. I know that.

Finn: When the humans moved to Ooo, my mother set up a baby monitor in my new bedroom! Everybody knows I turned off the Guardian because I wanted to Susan Strong and Frieda again. You're not even knowing what you're doing! Gumbald's army literally needs to be dead!

[The scene cuts as Tencent Pictures logo starts and it glitches then cuts back to Finn who has a total freak out.]

Finn: [explodes with panicked hysterical anger] This whole place! Everything you see is gone! You're the one living in the fucking dream, Phoebe! Because I know it happened! [distorting] It happened! [Flame Guard takes Finn to the dungeon]

[The scene glitches to black then fades to the Badlands in Ooo and the text says "Badlands, Land of Ooo. Four years after the Gum War." The text fades. The credits fade up and say "Warner Bros. Pictures and Columbia Pictures present", "in association with Cartoon Network Studios and Frederator Studios and Tencent Pictures", and "a Di Bonaventura Pictures/Platinum Dunes/K/O Paper Products production" then the credits fade. We see Tiffany Oiler who finds Finn and Jake then turns to Dr. Gross who survived an explosion.]

Tiffany Oiler: Dr. Gross, I know where to find Finn and Jake.

Dr. Gross: Of course you do, but I don't know why you're actually against me, Tiffany.

Tiffany: Yeah, well, I trust Finn and Jake, and they have a better understanding of what's wrong or right than either of us. They're my friends, that's why.

Dr. Gross: Why can't you just obey me? This is for their own good.

[A rock passes Dr. Gross and Tiffany as they both gasp and turn around to see Bandit Princess, Ash, Ricardio the Heart Guy, Samantha, Me-Mow, Pete Sassafras, Sir Slicer, Peace Master and Scorcher.]

Bandit Princess: You pathetic waste of human flesh. I'd kill you right now even if I have to do it.

Dr. Gross: Who are you?

Bandit Princess: I'm Bandit Princess. This is Ash, Ricardio, Samantha, Me-Mow, Pete Sassafras, Sir Slicer, Peace Master and Scorcher. We were the members of Gumbald's Legion of the Candy Kingdom Haters.

Dr. Gross: Oh, I see. You were all the members of Gumbald's Legion of the Candy Kingdom Haters. Now then. Is there anything else I can help you all?

Bandit Princess: Well, I think there's something else you could help.

Dr. Gross: Oh, yeah? Like what?

Bandit Princess: Like coming up with a new empire name.

Dr. Gross: Excellent. I think it's time for a new empire. We'll be known as Mutant Exterminators. Tiffany Oiler, we're going back to the Land of Ooo.

Tiffany Oiler: Right away, Dr. Gross. It's time to capture mutants.

[Dr. Gross, Tiffany Oiler, Bandit Princess, Sir Slicer, Ash, Samantha, Ricardio, Pete Sassafras, Scorcher, Me-Mow, and Peace Master enter the rocket. The rocket starts and drills back to Ooo. The camera pans down to the hole and the title says "Adventure Time: Awakening." The title moves forward and the screen fades to black then fades back to Finn who is locked up in the dungeon in Fire Kingdom. The text appears and it says "Fire Kingdom. Today is Finn's 21st birthday at 6:00 am." The song plays "All Out of Love" by Air Supply then Flame Guard walks to the gate and unlocks it then the gate opens.]

Flame Guard: Mertens, you're free to go. Happy birthday.

[Finn stands up and the scene fades to Finn who walks back home. The scene cuts to Finn's new house as text appears and says "Finn's new house." Finn opens the door and sees his mother.]

Finn: Mom, I'm home.

Minerva: Oh. Good morning, son. How's the interview?

Finn: Well, it went like fun.

Minerva: Oh. Well, that's great to hear. [chuckles]

Finn: Yes, I think we all know how everything's great.

[Finn takes a look at the picture of Martin Mertens.]

Minerva: Finn? Is there something wrong?

Finn: [sighs] Yes. All I ever really wanted was to see my father named... Martin Mertens. Every time I sleep, I saw my father right in my dreams. And when I woke up, I realize he's disappeared. I really, really missed him. I wish I could bring him back to life. Even Fern. I'll be at the Ice Kingdom. Come with me.

Minerva: All right.

[Finn, Jake and Minerva walk to the Ice Kingdom. The scene cuts to the Grass Plains as Finn, Jake and Minerva continue to walk while the song plays "No Problem" by Pusha T then they see a poster where it says "Remember Gum War. Report mutant activity." The scene cuts to clips from Come Along With Me with news banner from Fox News, CBS and CNN.]

Shepard Smith: The Great Gum War was an event that permanently changed our world.

John Dickerson: An alien from Mars, known as GOLB, granted a wish from Betty Grof, the wife of Simon Petrikov, as she wished for the crown to keep him safe after biting Finn's arm off.

Anderson Cooper: A swift act of Congress in California put an end to all joint operations between the humans and the mutants, ending the alliance. They're urging everyone to report suspicious mutant activity.

[At an examination room, Bandit Princess is having a meeting with Dr. Gross, Ash, Samantha, Me-Mow, Sir Slicer, Peace Master, Scorcher, Pete Sassafras, Ricardio and Tiffany Oiler then the song ends.]

Bandit Princess: As this meeting knows, the Great Gum War was a defining day for the Land of Ooo four years ago. The day millions of people realized that never again can we allow mutants to fight our battles for us. A handful of mutants were given sanctuary after joint-combat operations were abolished. Fewer than a dozen mutants are still on the run thanks to our new unit "Mutant Exterminators." As for the mutant sociality, our objective remains to keep it in control in the island. [they watch footage where Shermy finds Finn's arm in the future] Word has it Shermy, a reincarnation of Finn P-G-8-7 Mertens, may have gotten hands on his arm. Apparently, the Japanese are starting a bidding war. [they continue to watch the footage again] The new era has begun. And the age of the mutants is over.

[The scene cuts to Finn, Jake and Minerva who arrives at the Ice Kingdom as Toronto rides on a horse where he listens to "Back in Black" by AC/DC on radio then he turns the radio off. He jumps off the horse.]

Toronto: Hey, Finn.

Finn: Oh. Hey, Toronto. I know you from Flame Princess' rap contest.

Toronto: That's right. You know me. So, how's the arm going?

Finn: Well... it's missing. GOLB bit it off. You didn't invite us for the Gum War

Toronto: Oh, well, that's okay. I missed the war.

Ice Thing: Hello, Finn. How can I help you?

Finn: Oh. Hey there. I was wondering if there's Patience St. Pim.

Ice Thing: Oh. Okay. Let me show you Patience St. Pim.

[Finn and Ice Thing discover until they found Patience St. Pim inside a giant ice egg.]

Ice Thing: There she is, Finn. Isn't she a beauty?

Finn: Yes. Let me just take a look at it. [he walks to it and cracks the giant ice egg a little as it leaks water] Water? What the hell happened to you? [puts invisible duct tape on the small crack] Hey, is it for free?

Ice Thing: Um... yes.

Jake: So we're buying Patience St. Pim for free?

Finn: Yes, that's what we're gonna do. Look, I know you love Lady Rainicorn. And besides, she's your wife. You got five children and one granddaughter who loves skateboarding.

Jake: Oh, that's right. I have five kids and one granddaughter. So who taught you how to buy people?

Finn: Maybe someone did. [sighs] Listen, I know what I'm doing. We're taking her to our new house. And I know I lost my arm, but we're gonna be fine, Jake. You know you can carry things, right? I mean, that's what starchilds do. And you know you're married to your wife. I'm sorry.

Jake: It's all right, Finn. I believe you.

Finn: I know Fern would be very proud of me. [Jake chuckles softly] Let's take her to our house. [Jake and Minerva bots roll the giant ice egg to Finn's new house]

[Outside at Wizard Battle Arena, Bandit Princess rises from the ground and uses binoculars with radar to hunt down Flint then she sends out her team.]

Mutant Exterminator Team #1: All right, let's move.

Mutant Exterminator Team #2: Go, go, go, go. Give me two. Give me two.

Ash: [cocks his M16 rifle with laser] Take the back, nice and easy. [the ice soldiers take the back]

Mutant Exterminator Team #3: [over radio] All right, hold what you got.

Sir Slicer: Activate the mini-drones.

Mutant Exterminator Team #2: Yes, sir. [they activate the mini-drones and find a hiding mutant]

Me-Mow: Got a hiding mutant. The backstage. Closest to the arena.

Mutant Exterminator Gunner #1: [over radio] Exterminator 0-1. Captured target area.

Samantha: [over radio] Set C-4 explosives.

[The team walks to the backstage.]

Mutant Exterminator Gunner #2: Bandit Princess, this is Exterminator 0-1. Eagles moving the patio closest to the backyard.

[The gunners talk indistinctly.]

Mutant Exterminator Gunner #3: Exterminator 4, Exterminator 4.

[The mini-drones fly to the backstage where Flint hides in the chest at the backstage.]

Mutant Exterminator Gunner #4: Breached site at backstage with the chest.

Mutant Exterminator Gunner #3: Have Extermination Platoon put C-4 explosives.

Mutant Exterminator Gunner #4: Let Dr. Gross know we're moving to the backstage!

Mutant Exterminator Team #1: Alpha, take backstage. Omega, take the field.

Mutant Exterminator Team #2: Shift right, shift right.

[The gunners continue to talk as the team member 2 puts the C4 explosive and the detonator on the door. The detonator beeps.]

Peace Master: Cracking walls!

[The C4 explosives explode as Flint falls from the chest, groaning.]

Flint: No!

Mutant Exterminator Team #1: Hit him, hit him, hit him!

[the team members fire their guns and Boeing AH-64 Apache launches missiles.]

Mutant Exterminator Gunner #4: Fire! [Ice soldiers launch M72 launchers at Flint]

Pete Sassafras: [over radio] Missiles out. Danger close.

[the missiles land on the ground then Flint groans and runs away.]

Ash: He's running! Move!

Mutant Exterminator Gunner #2: He's on the run! He's on the run!

[the ice gunner fires his M16 with a laser as Flint dodges bullets until Flint gets his leg shot by a sniper rifle.]

Flint: [groans] No! Please! Hold your fire! [mumbling] Hold! Hold fire! Can't you just see? I've been injured! [continues groaning]

Mutant Exterminator Team #3: [over radio] Box him in. Box him in.

Flint: My name's Flint, Phoebe's brother. I'm a friend! [groaning] I'm a mutant!

Ash: Then why are you running?

Flint: Patience St. Pim recorded this message. [switches tape recorder on]

Patience St. Pim: [on recording] Boy, did I fail deep. Well, maybe I'll try again in another thousand years. I'm not sticking around to see how it ends.

Flint: We're all hiding. All mutants are being hunted. We're all in danger!

Ash: The Legion of the Candy Kingdom Haters is dead. And now we're Mutant Exterminators.

[Bandit Princess uses her rocket launcher to launch a missile at the ground closest to Flint as he yelps]

Flint: What's wrong with you, people? [groans in pain]

[Flint throws fireballs at ice soldiers then they dodge them.]

Flint: No! Please. [gets knocked down and groans]

[Bandit Princess walks to Flint.]

Mutant Exterminator Gunner #1: Cease fire, cease fire.

[Bandit Princess uses her net.]

Bandit Princess: He's mine now.

Flint: Bandit Princess.

Bandit Princess: Humans, mutants. Like little children, always fighting. Making a mess out of the Land of Ooo. Then I've got to clean it up. There is one way you survive. Tell me where she's hiding. Where is Patience St. Pim?

Flint: She was taken by Finn and his family.

Bandit Princess: Very well, then. [captures Flint with the net] And one more thing. Thank you for telling me where she is.

[the Sikorsky MH-53J Pave Low helicopters arrive as the ice soldiers, Bandit Princess and her team members enter them and fly away to Dr. Gross's rocket. The scene cuts to Martin who wakes up as he grunts and walks to his time machine. He travels to the future in Ooo. At Ooo in a 996 years, the text appears where it says "Land of Ooo, in the distant future." Shermy and Beth climb down the tree as he looks at Finn Sword.]

Shermy: Wow. Look at this sword. I wonder what Fern's up to.

Beth: Don't worry, he'll come alive. [Fern comes alive] See? He comes alive.

Fern: I'm alive.

[the time sphere appears and opens as Martin's time machine lands on the ground. The time machine door opens as Martin walks to Shermy, Beth and Fern.]

Martin: Hello.

Shermy and Beth: Hello there.

Martin: My name's Martin Mertens, and I'm here to take you back to the past so we can change the future.

Shermy: The past?

Martin: Yes, the past.

Fern: Hi, Martin Mertens. I'm Fern.

Martin: Oh. Hello there. Shermy, what you got there?

Shermy: [shows Finn's arm to Martin] Finn's arm. Your son.

Martin: I... I remember my son. I really wish I could meet him and his mother. Wait, his mother lives. I have a wife. Her name's Minerva Campbell.

Shermy: Then let's go.

[Shermy, Beth, Fern and Martin walk to the time machine and travel back to the present. At Grass Plains, the time sphere appears and reveals Simon Abadeer and he looks around while the song plays "Gangsta" by Nicki Minaj. At Candy Kingdom, a time sphere opens as Martin's time machine lands on the ground after the song ends. The time machine door opens then Shermy, Martin, Fern and Beth walk out of the time machine.]

Martin: Well, here we are. The past.

Beth: We're in the past.

Fern: Wow. I remember this place.

Martin: Hey, you still have Finn's arm.

Shermy: Uh-huh.

Martin: Then let's meet him tonight.

[at the Fire Kingdom, Cinnamon Bun reads a book then Flame Princess walks behind his back and licks his right arm.]

Cinnamon Bun: Oh! Hey. [chuckles]

Flame Princess: You reading the book, Cinnamon Bun?

Cinnamon Bun: Yes, I think this book takes me, like, 197 pages.

Flame Princess: I know how long it takes. And maybe you should take Bun Bun somewhere else.

Cinnamon Bun: Oh, yeah? Which place would you like me to take Bun Bun?

Flame Princess: Well, maybe you can take Bun Bun to Tree Trunks house so Bun Bun can be friends with Sweet P. And then you can take Bun Bun and Sweet P to the Candy Kingdom so they can be friends with Lemonhope.

Cinnamon Bun: Oh, yeah. I knew Tree Trunks.

Flame Princess: You can talk to her and her husband Mr. Pig. It might be a fun meeting while Bun Bun plays with Sweet P nicefully. Then you know you like reading books as everyone reads every book at the library.

Cinnamon Bun: Phoebe, I do love reading books. Listen. [Flame Princess sits on his lap] Imagine a jetliner with a pilot that never gets tired, never makes mistakes, and never shows up to work with a hangover. I'm kidding. I quoted Terminator 2: Judgment Day.

Flame Princess: Why do you think that a pilot should fly on a jetliner? I think your mind and your heart are always inside your body. And it really matters if you love Bun Bun.

Cinnamon Bun: [sighs] I know it does. And yes, I love Bun Bun.

Flame Princess: Then it's time to take Bun Bun to Mr. Pig, Tree Trunks and Sweet P. [snickers]

[Bun Bun opens the door.]

Cinnamon Bun: Hey-hey! [chuckles] Let's see Sweet P!

Bun Bun: Go see Sweet Pig Trunks? Good idea! Let's go to the orchard.

Cinnamon Bun: I'll be back later. Let's go.

[Cinnamon Bun and Bun Bun walk to Tree Trunks' house as Cinnamon Bun closes the door.]

Flame Princess: Hmm. I wonder what Finn's... Wait a minute. Did he just... I bet that's Patience St. Pim.

[At Finn's new house, Finn uses his hand.]

Finn: All the way!

[Jake and Minerva bots place Patience St. Pim at the backyard.]

Finn: Perfect. The backyard sounds great.

[Flame Princess lands on the ground and walks to Finn.]

Finn: Oh. Hey, Flame Princess

Flame Princess: Finn, tell me this isn't right.

Finn: All right, I found Patience St. Pim. I rolled her to the backyard.

Flame Princess: You know you can't do anything purposely.

Finn: Look, I could prove a new arm and that's why you're gonna make a new one from lava.

Flame Princess: I don't see what you're getting into this.

Finn: [clicks tongue, sighs] All right, I have a confession to make myself. I'm the one who wrote those hurtful letters that got you and Ice King mad at each other. I got you to break up with me as you need some time alone. I don't have a girlfriend anymore. I was only trying to get you back. The horrible, sad truth is, I'm just a virgin! [hugs Flame Princess crying]

Flame Princess: Is that true, Finn?

Finn: Yes, it's all true. And here's the real apology. [sighs] I'm sorry. I'm sorry for writing that hurtful letter that got you mad at Ice King. I'm also sorry for making you fight him, when he could've killed you. I understand you're still mad at me, for what I did. And you'd be right to be mad at me. I put you in danger, I got you to break up with me, and it's all my fault. I love the way you fight, but it was my greed, that blinded me. I'd never realized what I had done until it was too late.

Huntress Wizard: Good, good.

Finn: I must be the biggest, dumbest, most stupidest idiot in the world. I can't do anything right.

Michael Bay: This is such a good apology.

Finn: [pulls the sad puppy face] What I did was selfish, stupid and wrong. I never should've done it in the first place. Will you ever forgive me? [frowns]

Michael Bay: Now he's pulling the sad puppy face. Now she's gonna forgive him.

Huntress Wizard: Perfect. Now all he has to do is hold it until she forgives him.

Flame Princess: [sighs] Finn. Look. I said, "I need some time alone." I didn't say, "It's over, between us."

Finn: [becomes neutral] But... Does that mean... You've?

Flame Princess: Yes, Finn, I forgive you.

[Finn, Jake, Huntress Wizard, Minerva and Michael Bay become surprised.]

Finn: Yes!

Flame Princess: Oh, and on one condition. Don't. You. Ever. Do. Anything. That. Stupid. Again! Deal?

Finn: [hugs Flame Princess without burning] Deal. [Flame Princess sighs and hugs him back]

Jake, Minerva, Huntress Wizard, Michael Bay: Aw.

Finn: I better call Cinnamon Bun and tell him she forgave me again. [calls Cinnamon Bun]

Cinnamon Bun: [on phone] Hello?

Finn: Hey, Cinnamon Bun. You remember me?

Cinnamon Bun: [chuckles] No, should I?

Finn: Well, maybe you should because I got shown up by you.

Cinnamon Bun: Finn.

Finn: Oh, so you do remember me. That's funny because I don't remember you which must mean you're her only knight.

Cinnamon Bun: [huffs] I was under the impression that you were born a virgin.

Finn: Oh, yeah, I've never been a virgin because I didn't have any girlfriend to marry, because you stole her from me!

Cinnamon Bun: Oh, come on, Finn. Flame Princess and I are just friends. I couldn't have stolen your girlfriend. I've been a good friend to her all day.

Finn: God. I guess I was wrong. We don't have to involve the authorities, do we, Cinnamon Bun? I mean, I made a confession to Flame Princess, and it's all true.

Cinnamon Bun: Really?

Finn: Yes, and that's why I got her back. I guess we should say goodbye.

Cinnamon Bun: Oh. Okay. Goodbye.

[Finn and Cinnamon Bun hang up. At sunset, Finn walks to the tree with a Finn Sword.]

Finn: [sighs] Best thing that ever happened, Fern. She's the best thing that ever happened. You'd be happy.

[Finn turns around and sees Martin as he feels shocked.]

Finn: Huh?

Martin: Hey, kiddo.

Finn: Dad? Is that you? [pokes Martin's belly and squeals excitedly] Dad! It's you! You're alive! I thought you were transforming into GOLB and defeated by Betty Grof and... [Martin shushes]

Martin: Yes, Finn, I'm alive. [chuckles] Listen, I wasn't transforming into GOLB. GOLB's been defeated by Betty Grof where she made a wish for the power to keep Simon Petrikov safe. And look, there's someone I'd like you to meet.

Shermy: Hi.

Finn: Oh. Hi, there. I'm Finn Mertens. Who are you?

Shermy: I'm Shermy and she's Beth.

Beth: Hi, there.

Finn: Oh. Hi.

Shermy: Do you remember Fern?

Finn: Uh, should I remember him?

Shermy: Well, maybe. Then meet him.

Fern: Hi, Finn. Surprise to see me?

Finn: Fern! [hugs Fern] Oh! It's really good to have you back. You're alive.

Fern: Thanks.

Finn: Hey, Shermy. What'd you find?

Shermy: Your arm. [shows Finn his arm]

Finn: Wait. You found it. How'd you...

Shermy: I found it on the ground. Wear it again after you clean the dirt off.

Finn: Okay. [cleans his mechanical arm, wears it again and it moves] Wow. It moves. Thanks, Shermy. Oh! And guess who I got her back.

[Flame Princess walks to Finn.]

Finn: This is my ex-girlfriend, Flame Princess.

Flame Princess: Hi.

Shermy: Oh, hey, there. Are you Phoebe?

Flame Princess: Yes. You may call me Phoebe. I'd better go. Cinnamon Bun needs me. Goodbye.

Finn: Okay. See you soon, Phoebe. [Flame Princess flies to Fire Kingdom] I've never seen one like you before. Almost human.

Shermy: I am human. Half-human, half-cat.

Jake: What the... Beth?

Beth: Hi, there.

Jake: Oh. It's really good to see you, my great-granddaughter.

Finn: Anyway, we'd better go home so we can have a good sleep.

Shermy: Oh. Okay.

[outside at Finn's house, the rooster crows as the sun shines risingly. In Finn's house, Finn, Martin, Jake, Shermy, Beth and Fern wake up and yawn.]

Finn: Oh. Good morning.

Minerva: Good morning, son. I'll make you some... [she gasps and sees Martin] Who's that?

Martin: Don't worry, Doc. You'll scan me. [Minerva scans Martin's DNA]

Minerva: It is you. Oh, my God, I can't believe you're alive. You're back. My wonderful husband Marty. Oh, you have a big belly. And look at you, you have a beard.

Finn: Mom, Dad, come here. You're not gonna believe this.

[Finn, Minerva, Fern, Martin, Shermy, Jake, and Beth run to the backyard.]

Finn: Look, it's a small crack. When it leaks cold water, I put a duct tape on it. [removes the duct tape and puts an underwater microphone through the egg as Patience St. Pim speaks distortedly after Finn presses the play button on the radio] Oh, yeah. I don't think it's a giant egg at all. [gasps] I think we just found Patience St. Pim.

Huntress Wizard: Wait, Finn, how'd you know the ice elemental? Oh, I mean, good morning, my love.

Finn: Good morning, babe. Great news. Shermy found my arm. He's from the future with Beth and my father Martin Mertens. And that's why my father came back to Earth.

Huntress Wizard: Wow. That's fantastic, my love.

Finn: Thanks. Anyway, I got Flame Princess back together after I made a confession.

Huntress Wizard: Finn, I understand.

Finn: Also, I think Princess Bubblegum's the one who locked my old girlfriend up all those years ago.

Huntress Wizard: [gasps deeply] Oh, dear. [accidentally faints on an egg]

[The egg cracks and shatters then Patience St. Pim falls to the ground.]

Finn: Whoa. I didn't know the ice egg cracked. I need a gun. The .45 longslide with laser sighting.

Jake: Here you go. [gives Finn the longslide with laser sighting]

[Patience St. Pim groans and yawns as she sees Finn pointing the longslide pistol at her.]

Finn: Talk. Talk fast.

[Patience St. Pim quickly wakes up, disarms Finn and pushes him against the wall.]

Patience St. Pim: You first.

Finn: My name is Finn Mertens. Four years ago, the Gum War was a totally complete success. And now Shermy found my arm after he and Beth went back in time with the help of my father.

Patience St. Pim: Finn, I'm in your debt now. My name is Patience St. Pim. I'm the ice elemental princess. [she groans and her skin on the face bleeds a small one] I really need... assistance right now.

Finn: Don't worry, Huntress Wizard's here to help you. So, you'll tell me what the hell's going on.

Patience St. Pim: All right. It was an ambush, a trap, set by Bandit Princess. [coughing] And that's why you found me. How'd you find me?

Finn: Well, I had to roll you to the backyard at my house where I live with Jake and my mother Dr. Minerva Campbell.

Patience St. Pim: Anything else?

Finn: I made a confession to Flame Princess known as Phoebe after I got shown up by Cinnamon Bun. And now I'm gonna kill him.

Patience St. Pim: But Cinnamon Bun's your friend. Why would you want to kill him?

Finn: I must terminate him by using the shotgun. Even Bun Bun. I'm sorry. I apologized to Flame Princess for real.

Patience St. Pim: Oh. Well, that's good to hear.

[At Dr. Gross's rocket, Dr. Gross orders Bandit Princess and her servants.]

Dr. Gross: Listen up, everyone. We found the location of an elemental mutant. And we're taking her as our prisoner immediately. Move out.

[Bandit Princess, Ash, Ricardio, Samantha, Me-Mow, Pete Sassafras, Sir Slicer, Peace Master, and Scorcher ride on nine Corvette Stingray cars to Finn's house. At Finn's house, Huntress Wizard reads a Game Informer magazine then she sees the Corvette Stingray cars.]

Huntress Wizard: Finn!

[The Corvette Stingray cars park at the front yard then Bandit Princess, Ash, Ricardio, Samantha, Me-Mow, Pete Sassafras, Sir Slicer, Peace Master and Scorcher exit the Corvette Stingray cars. Finn opens the door and sees the villains.]

Bandit Princess: Remember me, Finn Mertens? The Legion of the Candy Kingdom Haters? My friends and I are looking for the giant ice egg. It's a nice place you got there. I guess it's been for sale.

Finn: Well, thanks. She's not. That the egg you mean? It hatched.

Ash: Of course it did. You know, Mr. Mertens, we received a call from someone concerned about this egg.

Finn: Oh, no.

Me-Mow: That wasn't you?

Finn: Only thing I'm concerned about is you being on my property without permission. You know, we got a rule about people messing with people in the Land of Ooo. And I don't know what egg you're talking about.

Me-Mow: The kind that cost a lot of money. Search the property!

Finn: What do you mean, "search the property"? You don't have a warrant!

Sir Slicer: My face is my warrant.

Huntress Wizard: Wait. But if you people find the egg, we get a reward. Right?

Mutant Exterminator Team #1: Viper 1-5 holding, point alpha. [at the same time, Dr. Gross watches the teams search via the monitors back at the control room in her rocket] Charlie team, hold tight. Lock it down. [the team enters Finn's barn and the tape recorder plays "Can't Get Over You"] What the hell is that?

Mutant Exterminator Team #2: Just some dumb inventor.

Mutant Exterminator Team #3: Clear.

Mutant Exterminator Team #4: Clear right.

Mutant Exterminator Team #5: Clear.

Mutant Exterminator Team #3: Clear.

Mutant Exterminator Team #1: Three sixty-seven twenty. Heads on a swivel. [as they team finishes checking the barn] Let's go. There's nothing here. [the team walks out of the barn; to Pete Sassafras] There's no signs. We got nothing, sir.

Mutant Exterminator Team #6: [to Bandit Princess] Ma'am, we have a cracked ice egg shell in the trash.

Shermy: Cracked? I carried that to the trash! You said it was melting, man! I could be dead. Right?

Finn: Okay. Look, yes. I found the egg, all right? I bought it at the Ice Kingdom. I put it at the backyard. This morning, it completely hatched. When? Where? I don't know. I swear to God. That's as much as I know about her.

[Dr. Gross watches this from the monitors; to Ash]

Dr. Gross: Her. He said, "Her." He knows who the son of a bitch is.

Ash: Finn Mertens.

Finn: Yes?

Ash: I think you literally said, "Her." [to his team] Take them down!

Finn: What? [one of the team members grabs hold of Huntress Wizard and starts dragging her off]

Huntress Wizard: Hey! Let me go!

Finn: They don't know about the egg! I know! Let my girlfriend go!

Me-Mow: What kind of a man betrays his flesh-and-blood brethren for the ice elemental princess? Get this guy out of my sight.

Huntress Wizard: Get off!

Finn: Just let her go! They don't know about the egg!

Pete Sassafras: [to his team] All right! Load up! Search the perimeter!

Huntress Wizard: Shermy, you called, didn't you?

Shermy: No! I don't know any of these evil people! [to one of Dr. Gross's team who tries to drag her off]

Huntress Wizard: Oh, God! You're manhandling a woman! I'll kick your ass!

Finn: Let her go! [Finn goes to rush over and help Huntress Wizard but he gets knocked down]

Huntress Wizard: Honey! Let me go!

Mutant Exterminator Team #1: You're not going anywhere!

Huntress Wizard: Finn! [two men grab hold of Shermy]

Shermy: No! You're not taking me! I'm just a human-cat hybrid! [they drop him to the ground]

Mutant Exterminator Team #1: Easy, mutant.

Shermy: Okay, okay, okay. All right. Okay. All right. I was wrong.

Dr. Gross: Bandit Princess, use Huntress Wizard. [Huntress Wizard is pushed to the ground]

Huntress Wizard: Oh, my God! Ahh! [Ash points his M16 with laser at Finn]

Ash: Now, you got one minute. Where's the ice elemental? [his team point their guns at Finn's family]

Finn: You're gonna shoot my parents?

Peace Master: [scoffs] If I have to. [Huntress Wizard groans]

Huntress Wizard: Please don't shoot me! Please!

Finn: Look, I don't know. I told you everything that I know! She's gone! She left. She was in the barn, I swear to God! Just let her go!

Huntress Wizard: [choking] Please, please!

Finn: She was in there! Let her go!

Ash: 40 seconds.

Finn: I'm telling you the truth! She was in there!

Huntress Wizard: Finn!

Finn: Tell them to get away from my girlfriend now! [we see Patience St. Pim hiding under the barn]

Huntress Wizard: [crying] Finn!

Finn: You touch her, and I'll kill you all! [suddenly Ricardio shoots his gun near Finn's head]

Ricardio: You got 20 seconds.

Dr. Gross: I need the truth, now! [Huntress Wizard continues to weep]

Huntress Wizard: Please.

Samantha: 10 seconds left. [just then Patience St. Pim storms out of the barn]

Patience St. Pim: Here I am! [he fights some of the team, Finn grabs hold of Huntress Wizard]

Finn: Take cover!

Patience St. Pim: Finn! They're gonna kill you! Get out of here!

[Finn, Shermy, Jake, Beth, Minerva, Fern, Martin and Huntress Wizard make a run for it, at the same time, a Boeing Apache AH-64 helicopter launches the missile at the frontyard and it explodes.]

Mutant Exterminator Team #1: Push right! Headed to the Candy Kingdom!

Finn[suddenly a plane swerves in, knocks down one of the team member and it stops just ahead of Finn, Shermy, Jake, Beth, Minerva, Fern, Martin and Huntress Wizard, the plane door opens, we see it's Susan Strong and Frieda.]

Susan Strong: Come on, let's go! Get in the plane, everyone!

Finn: Everyone, let's go!

[Finn, Shermy, Jake, Beth, Minerva, Fern, Martin and Huntress Wizard enter Susan's plane and she flies to the sky.]

Dr. Gross: [on walkie-talkie] Bandit Princess, don't let them get away.

Bandit Princess: Got it. Send out the F-22 Raptors.

[Bandit Princess and her team follow Patience St. Pim, now in flight as she flies off, she dodges bullets after the ten F-22 Raptors try to shoot her, meanwhile back in Susan's plane.]

Finn: Susan, Frieda, you came back for us.

Susan: Yes, Finn, we came back for all of you.

Finn: I got Flame Princess back so she loves me again.

Susan: What? She actually loves you?

Finn: Yes, I found my mother and father. His name's Martin Mertens. He's Fern, Shermy and she's Beth and my girlfriend Huntress Wizard.

Susan: Huh. Now that's a lot of people. I picked up Lemonhope.

Finn: What? He's on your side?

Susan: Yes.

[a missile passes the plane and they gasp.]

Finn: What the hell was that?

Susan: F-22 Raptors.

Finn: Oh, shit. Shermy, take the turret.

Shermy: Aye-aye, Sir Finn.

Finn: And one more thing. You know the music, time to dance.

[Shermy enters the turret and shoots an F-22 Raptor while the song plays "Ten Thousand Fists" by Disturbed.]

Shermy: This turret really kicks ass. One down, nine to go.

[Outside in the sky, the plane dodges bullets from the F-22 Raptors while the turret fires at them where they dodge.]

Finn: Stay on those F-22s.

[The turret fires at the engine as an F-22 Raptor falls down then Ash ejects and pulls the parachute.]

Dr. Gross: Do not let them get away! Do not let them get away!

[The plane door opens as Finn uses the bazooka and fires at eight F-22 Raptors then they fall down where Me-Mow, Bandit Princess, Sir Slicer, Peace Master, Scorcher, Samantha, Ricardio, and Pete Sassafras eject and pull the parachutes then the song ends.]

Frieda: Good job.

Finn: Thanks.

Dr. Gross: [on radio] I'll bet you wish you could see my face right now.

[Dr. Gross throws the walkie talkie across the room angrily, back at the forest, Bandit Princess sees the plane.]

Bandit Princess: We'll get them sometimes.

[Patience St. Pim enters the plane.]

Finn: [to Susan] Do you even remember me? The grass curse? Losing my arm at the beach? Traveling to Founders Island? My parents? Ring any bells?

Susan: Yes, I remember everything.

Patience St. Pim: Finn, are you all right? Let me have a look. [looks at Finn's arm] Say, I didn't know Shermy actually found your arm.

Finn: Of course he did.

Patience St. Pim: [sighs] Finn, it was stupid of you to find me. Goddamn it, Finn, you have to be smarter than that. You're too important! You cannot risk yourself, even for me, do you understand? Jesus, Finn, you almost got yourself killed.

Finn: But... I had to find you to get you out of the Ice Kingdom. I'm sorry.

Patience St. Pim: You didn't need help. I can try again in the future. [Finn's tear escapes]

Frieda: What's wrong with your eyes?

Finn: Nothing.

Patience St. Pim: Hmm. Look, after all we've done, Bandit Princess is hunting us and villains are helping. But I fear we've been all targets now.

Finn: We're here!

[Susan lands her plane at the cave. The plane door opens then Finn, Frieda, Susan, Patience St. Pim, Jake, Shermy, Beth, Minerva, Fern, Martin, Lemonhope and Huntress Wizard walk out of the plane.]

Lemonhope: Well, here we are. The cave. Oh, hi, Finn.

Finn: Oh! Welcome back, Lemonhope.

Lemonhope: [shows Finn the mini drone] See? I got it.

Finn: Wow. That's great, Lemonhope. [shows his family the footage of a mutant raid] This is the footage of a mutant raid. It has videos. Watch what happens here. [touches the video as the Mutant Exterminators Team members capture Rattleballs]

Rattleballs: [on video] Please! No! I'm a mutant! I'm a mutant!

Jake: Oh, that's Rattleballs.

Finn: They captured him.

Jake: Savages.

Finn: And later, this ice elemental princess comes to haul her off. Dr. Gross. She survived an explosion with Tiffany Oiler.

Fern: So that's why the Legion of Candy Kingdom Haters had been changed to Mutant Exterminators.

Finn: Yes, they captured them as their prisoners.

Jake: [gasps] It's the Vampire Prince! Everybody, hide!

[they hide inside the plane. Simon Abadeer walks and looks at the plane then walks to Marceline's house. They come out of the plane.]

Jake: Is he gone, Finn?

Finn: So far, so good.

Jake: Oh, thank God.

Frieda: Who's that?

Finn: That, Frieda, is Simon Abadeer, the Vampire Prince.

Frieda: Whoa. I didn't know Simon Abadeer just became the first time traveler.

Finn: Precisely.

Fern: Now that's something you don't see every day.

Finn: Good word, Fern.

Fern: Thanks. [chuckles]

Finn: [clears throat] He's the son of Marceline Abadeer and Bonnibel Bubblegum, and now, he's the time traveler.

Shermy: So, is he, like, a Terminator or something?

Finn: Approximately.

Shermy: Oh, you've gotta be shitting me.

Finn: No, I am not shitting you.

Martin: Very funny, son.

Finn: Everyone, I have sworn to never write hurtful letters.

Jake: Big mistake.

Finn: But when I find out who's behind this, I'm changing the past.

All: Hooah!

[At the cave, Simon walks to the front door and knocks. The door opens as Marceline sees her son from the future.]

Marceline: Who are you?

Simon Abadeer: I'm Simon Abadeer. Are you my...

Marceline: It is you. Oh, my God, I can't believe you're from the future. You're wonderful. [chuckles and hugs her son] My son became the first time traveler. Oh, you're so big. You're just like Marshall Lee. Bonnie, come here. It's our son.

Princess Bubblegum: [gasps softly] Oh, my God. You came for us. You're here. You're just like her father. I knew you'd come for us, son.

Simon Abadeer: [enters her house] Of course I came for you two, my mothers. [chuckles and sees Hunson and Marion, his grandparents] Grandmother. Grandfather.

Hunson Abadeer: Who are you?

Simon Abadeer: I'm Simon Abadeer, your grandson.

Hunson: [gasps softly] I have a grandson.

Marion Abadeer: Hi. Do I know you from the future?

Simon Abadeer: Uh, no. I mean, yes. You know me. Simon Abadeer, your grandson.

Marion: My grandson became the first time traveler? That's awesome. I'm really, really proud of you.

Simon: Thanks so much.

[Outside at the Fire Kingdom, Finn, Jake, Martin, Minerva, Fern, Shermy, Frieda, Beth, Susan, Huntress Wizard, Lemonhope, and Patience St. Pim walk to the front door.]

Patience St. Pim: Are you sure this is the right place?

Finn: Yes, I'm pretty sure.

Patience St. Pim: Do you even know what happens to her?

Finn: Because I love flame Princess.

Patience St. Pim: Yeah, but, didn't she break up with you after writing the letters?

Finn: [sighs] Yes, she did. I'm the one who wrote the letters. And she needed some time alone.

Patience St. Pim: Oh, no, no, it's all right. Everything happens, that's all.

Finn: Now stay right here. I'll be back.

Patience St. Pim: But I thought...

Finn: You heard me. [walks to the front door]

[Finn uses his shotgun and goes against the wall then Cinnamon Bun opens the door as he looks at Finn]

Cinnamon Bun: Finn Mertens. [Finn attempts to shoot Cinnamon Bun then Patience St. Pim stops him]

Patience St. Pim: Finn!

Finn: I'll kill you! I'll kill you!

Patience St. Pim: What the hell are you doing?

Finn: Let me have it!

Patience St. Pim: No! Finn, you need to calm down.

Finn: He took Flame Princess from me!

Patience St. Pim: Is that true?

Cinnamon Bun: Yes. But I'm not what you think I am.

Finn: I'll kill you, you son of a bitch!

Frieda: Finn, if the prince can help...

Finn: He's not her prince! He's the only enemy that took my girlfriend!

Frieda: It doesn't matter! Stop it!

Finn: [stammering] But why?

Frieda: Because he's her only prince. There's no other way.

Finn: I'm not here to kill you, Cinnamon Bun. I'm here to challenge you for Flame Princess.

Cinnamon Bun: Is that so?

Finn: Absolutely. I call it an ass-kicking.

Cinnamon Bun: Very well, then. Today, we fight at the coliseum.

[At the Fire Kingdom Coliseum, the crowd talks indistinctly. In the backstage, Finn wears the gladiator armor. Shermy and Beth walk to him]

Beth: Finn, nobody else is gonna die because of us.

Shermy: And you better be careful not to get killed.

Finn: I will, Shermy. I promise.

Patience St. Pim: Hey, Finn. I hope I'm not interrupting anything. Listen, if you want Flame Princess back, you'll have to be the rightful king.

Finn: All right. I'll do it.

Patience St. Pim: Very good. Now move out there and show him who's the prince. If all else fails, we'll have to rescue you.

Finn: Yes, Patience St. Pim.

Patience St. Pim: Come on, let's go.

[they jog to the seats at the top]

Patience St. Pim: I know you're scared, but now I'm right here to protect you.

[The scene cuts to Cinnamon Bun who wears the gladiator armor as he walks to Finn.]

Cinnamon Bun: Well, Finn. I guess this is the one you wanted.

Finn: Yes. I'm ready for the challenge and it's called... I don't know.

Cinnamon Bun: Listen, the challenge is called "The Sword Fight Competition."

Finn: Oh, yeah. I knew the naked name. Sorry. Funny name.

Cinnamon Bun: When the time comes, I'll just truly enjoy destroying you.

Finn: We'll see about that.

Cinnamon Bun: All right, you made your point. I'll make my speech when the competition begins.

Finn: Good. You go do that... if the competition begins.

Cinnamon Bun: [groans] Who cares about the competition?

[Cinnamon Bun walks outside as crowd cheers and uses his sword while the drums beat.]

Cinnamon Bun: Welcome, people of the Fire Kingdom, to the Sword Fight Competition! [crowd cheers and silents] The Sword Fight Competition is the ultimate event that you're about to witness that Finn Mertens has come to Fire Kingdom to challenge me for Flame Princess! And now, everyone, my competitor of the challenge... is Finn Mertens!

[Finn walks outside as crowd boos]

Fire Citizen #1: Virgin bastard!

Fire Citizen #2: You're gonna die, you human freak!

Fire Citizen #3: You'll never be king!

[Finn and Cinnamon Bun put their helmets on. Drums beat rhythmically as camera pans up to Huntress Wizard, Martin, Lemonhope, Minerva, Jake, Frieda, and Susan Strong who sit on the seats at the top with Patience St. Pim, Shermy and Beth.]

Shermy: Never thought I'd see the day when Cinnamon Bun looks like the king of Fire Kingdom.

Martin: The challenge is to fight as the winner can be the king.

Patience St. Pim: Maybe that's the good reason we should watch. But don't you think that Simon Petrikov has to conjoin Ooo and Aaa? But you wouldn't turn into GOLB again, would you? Would you prefer to rip Finn's arm off again?

Martin: I wouldn't do that again, if you know what I'm talking about.

[The scene cuts to Finn and Cinnamon Bun who draw their swords.]

Finn: You have a golden sword. Powerful, but just too soft. I weld Phoebe's father's. And now you'll never be king!

[Cinnamon Bun yells and duels Finn as the song plays "Pretty Handsome Awkward" by The Used. Finn tries to decapitate Cinnamon Bun, but he dodges. Cinnamon Bun kicks Finn as he grunts and lands on the ground. Cinnamon Bun and Finn charge at each other. They duel again as Cinnamon Bun uses his legs to throw Finn to the wall. The song ends as Finn groans then he uses jetpack to fly and duel Cinnamon Bun who uses jetpack. They duel as crowd cheers. Finn and Cinnamon Bun strangle their swords.]

Martin: I promised Flame Princess I'd protect my son.

[Cinnamon Bun tries to stab Finn's heart then Finn dodges and kicks Cinnamon Bun to the sky.]

Shermy: This isn't a competition. It's an execution.

[Cinnamon Bun and Finn charge at each other while they yell and clang their swords. A sonic wave hits the audience as they gasp and cheer again. Finn and Cinnamon Bun land on the ground, charge again and duel until Cinnamon Bun tries to kill Finn but gets his face punched ugly. Finn destroys Cinnamon Bun's sword and crowd cheers. Finn shouts triumphantly and spares Cinnamon Bun's life.]

Cinnamon Bun: [stammers] What happened?

Finn: Yield the throne, Cinnamon Bun. Your face is ugly again. And what also happened is you just took Flame Princess from me. [Cinnamon Bun looks in the mirror and sees his ugly face]

Cinnamon Bun: [gasps] My face. My... My face! [hysterically] My face! No! [whimpering]

Finn: I'm the one true king. So hand me the jewel.

Cinnamon Bun: Okay. Here, take it. It's yours. [breathes shakily] Listen, I'm sorry you got shown up some years ago.

Finn: It's all right, Cinnamon Bun. You'll be her servant.

[Cinnamon Bun makes the crown and puts it on Finn's head.]

Minerva: The one true king.

Fire Citizens: All hail King Finn.

Finn: And one more thing, did you know that Princess Bubblegum's the one who locked Flame Princess up as a baby?

Fire Citizen #4: Yes, she did.

Finn: Well, I guess I'll call Princess Bubblegum. [calls Princess Bubblegum on his iPhone X]

Princess Bubblegum: Hello?

Finn: Hey, Bubblegum. You remember me? From the Gum War?

Princess Bubblegum: Yes, I do remember you. Can I help you?

Finn: I have one thing to say. Are you sure you're the one who locked Flame Princess up as a baby?

Princess Bubblegum: [sighs] Yes, I'm sure. Can I tell Flame Princess I'm sorry?

Finn: Sure. Phoebe, Bubblegum's on the phone.

Flame Princess: [uses Finn's iPhone X] Hey, Bonnie.

Princess Bubblegum: Hey, Phoebe. Listen, I'm sorry I locked you up as a baby?

Flame Princess: Oh, no, it's all right. I understand. That's all. Here you go. [gives Finn his iPhone X]

Finn: Thanks. And I have some great news. I defeated Cinnamon Bun by punching him ugly again, I got Flame Princess back, and I became the new king of Fire Kingdom.

Princess Bubblegum: Really? How's that possible?

Finn: I also have some news that Shermy found my arm after finding Patience St. Pim.

Princess Bubblegum: Patience St. Pim? Finn, how's that make the difference?

Finn: Well, it's super simple. I found her at the Ice Kingdom. Shermy and Beth are from the future and my father came back.

Princess Bubblegum: Wow. That's fantastic, Finn. I'm really happy at you. But why'd you think you want Flame Princess back? Don't you love Huntress Wizard?

Finn: Of course, I do, Bubblegum. Fern will also fall in love with Huntress Wizard. Isn't that right, Fern?

Fern: Yep, that's right. Will I fall in love with you, Huntress, my love?

Huntress Wizard: Sure. Anything's possible.

Finn: See, Shermy? That's what I told you.

Shermy: Oh, yeah.

[The searchlights turn on and spot Finn, Shermy, Jake, Beth, Flame Princess, Cinnamon Bun, Fern, Huntress Wizard, Martin, Minerva, Susan, Frieda, Lemonhope, and Patience St. Pim. Fire Citizens flee in panic. The camera pans up to Dr. Gross's ship where it floats. At. Dr. Gross's cockpit, Bandit Princess talks to Dr. Gross.]

Bandit Princess: We've spotted them, Dr. Gross.

Dr. Gross: Very good, Bandit Princess. Release the mechanical tentacles.

[Outside at the Fire Kingdom, the mechanical tentacles capture Finn and his family.]

Patience St. Pim: Finn, we'll get out of the rocket somehow!

Flame Princess: [struggling] Finn, help me! Don't leave me!

Finn: [his scream fades] No!

[The mechanical tentacles lift Finn and his family up. The scene fades to black then fades back to Finn who wakes up after he groans.]

Finn: Man, that was a crazy dream. Huh? Where am I? Am I in Dr. Gross's rocket?

Dr. Gross: Yes, you're approximately inside my rocket, P-G-8-7 Mertens. [walks to Finn] And it's very good to have you back. Bandit Princess wants to see you personally.

[Dr. Gross opens the cell door as Finn walks with her to Bandit Princess. Finn sees Rattleballs and Flint. At the cockpit, the door slides open. Finn sees Bandit Princess and Dr. Gross forces him to kneel down. Bandit Princess sees Finn, walks to him, and slaps his face. Finn groans.]

Bandit Princess: Excellent work, Dr. Gross.

Dr. Gross: Just doing my technologic job.

Bandit Princess: You thought we died from GOLB's wish, right?

Finn: Uh, yes?

Bandit Princess: Wrong. The Legion and I survived GOLB. I avoided talking to Ice King. And I still have this brand new sword. Things are looking up. And it's time to show you something new. [shows Finn the newest, latest, and most powerful superweapon The Super Extermination] The Super Extermination, this is the most powerful, newest, and latest weapon in the Land of Ooo.

Finn: Huh. Now that's something you shouldn't see every day.

Bandit Princess: Yep, and let me show you something. Demonstration. I'll shoot it with a Philly cheesesteak.

[Bandit Princess shoots a Philly cheesesteak with The Super Extermination then Finn gasps and she chuckles.]

Bandit Princess: I'm gonna ask you this once. Where is Patience St. Pim?

Finn: She's in jail.

Bandit Princess: See, doc? I told you. She's in the dungeon. Take him back to his cell with Jake, Shermy, Beth and his parents.

[Dr. Gross sends Finn back to his cell with Jake, Shermy and Beth. At the dungeon, Dr. Gross walks with Finn to his cell. She opens the cell door, he walks into his cell

Dr. Gross: Goodbye, P-G-8-7 Mertens, and thank you for telling the truth. [closes the cell door and walks back to the cockpit.]

Finn: [sighs] Great. She knows I'm P-G-8-7 Mertens.

Shermy: You can say that, my man.

Finn: Shermy. Jake. Beth. Mom. Dad. You're all here.

Minerva: That's right, son. We're in the cell. You have that live camera?

Finn: Yes, I have one. Let me record it. [presses record button and turns on the screen] I'm in. Can you see my camera? They captured Flint and Rattleballs.

Flame Princess: They captured my brother! I'm gonna tear them apart!

[Patience St. Pim picks the lock using her ice powers like a key. The cell unlocks open. Patience St. Pim releases all the prisoners. Finn, Shermy, Jake, Beth, Minerva, Martin, Flame Princess, Fern, Huntress Wizard, Susan, Frieda, Lemonhope and Patience St. Pim run to the cockpit while the prisoners flee in freedom. At the cockpit, Dr. Gross looks at The Super Extermination.]

Dr. Gross: So that's what the gun's made of. Simple coding. [puts the gun down and angrily bangs the table] Algorithms! [bangs the table again] Math! Why can't we make what we wanna make the way we wanna make it?! [shouts] Why?! [breathes heavily]

Toronto: Because you captured me like Finn and his family. Nobody puts a squirrel in the electric box!

[Dr. Gross presses the button. The floor shocks Toronto as he yells and talks gibberish then the door explodes and Finn and his family attack the cockpit]

Finn: Get out of here! All of you!

Beth: Space adventure's over, douchebags!

Toronto: Everyone! It's me! Break me out of this electric box!

Dr. Gross: Hey! Hey! Hey! Stop! That's science property!

Finn: They're not your property. [Dr. Gross stammers quietly] They were my friends. [Beth cocks and aims her gun at Dr. Gross]

Toronto: Oh, she ain't talking very much and now you got Jake in front of ya, huh?

Dr. Gross: Go ahead. Show us your true colors once and for all.

Martin: Just give me the word. I'll destroy her to oblivion.

Dr. Gross: Why don't you tell your wife Minnie here? That this is all the spoils of war. Dead mutant. Innovation what we do here is science because if we don't do it, somebody else will because you cannot stop science.

Finn: And Flame Princess is really in love with me.

Flame Princess: Are you really gonna keep saying that?

Dr. Gross: I gave them tests. I inject them into tubes.

Finn: The Land of Ooo knows we're not your science.

Dr. Gross: The land? The Land of Ooo will approve. We can make ice soldiers. Don't you get it? She doesn't love you anymore.

Shermy: That was cruel.

Finn: Everyone, we're done.

Toronto: We're done? We're not gonna kick a little bit of ass?

[Finn and his family leave her rocket. Dr. Gross sighs.]

Tiffany: Really? Finn and his family leave your rocket? What the Glob is this plan?

Dr. Gross: Let them go, Tiffany. We'll surprise Finn for his 21st birthday.

[Outside the Land of Ooo, the prisoners run back to their homes. Finn and his family walk outside.]

Finn: Isn't it wonderful? [chuckles]

Shermy: Yep.

Finn: You're free, everyone. Run back into your individual homes of Ooo.

Martin: Let's go now.

[Finn dreams of Marceline and Princess Bubblegum having a son named Simon Abadeer then Finn has an idea to assassinate them.]

Shermy: Finn, what is it?

Finn: I must assassinate them.

Shermy: You don't have to kill Marceline and Princess Bubblegum. Are you out of your damn mind? Just look at the picture. It's the tombstone of you.

Finn: [gasps deeply] Oh, my Glob.

Shermy: Check this out. Here lies Finn Mertens. He died from being single for not choosing the girl. That's why you're dead for not choosing the girl! Erected in eternal memory by his beloved Huntress Wizard.

Finn: Committed suicide by hanging his neck with the rope? What kind of a future do you call that? That's it! I'm going alone. You stay here.

[at Marceline's house, Finn knocks on the front door. Simon Abadeer opens the door.]

Simon Abadeer: Hello? [sees Finn wearing a mask and carrying an M16 rifle] Oh, shit. Hide!

[Finn tries to shoot Simon, but misses and destroys the living room.]

Marceline: Bonnie, take Simon and my parents and go. Go!

Princess Bubblegum: Come on, hide into the kitchen.

[Finn takes his mask off, throws it, enters her house and shoots Marceline in the knee with his Beretta 92 as she falls to the floor and screams.]

Simon Abadeer: Mom!

Princess Bubblegum: Marceline!

Finn: Stay where the hell you are! [points his gun at Marceline as Simon Abadeer protects her]

Simon Abadeer: Are you crazy? You can't kill my mom!

Finn: They're not your mothers. So get the hell out of my way! [Simon Abadeer moves out of his way] Get on the floor now! [Princess Bubblegum, Hunson, Marion and Simon Abadeer lay down on the floor, whimpering] Shut up. Shut up, shut up, shut up! It's all your fault, you goddamn bitch! It's all your fault!

Marceline: What?

Finn: I'm not gonna let you do it.

[Finn tries to murder Marceline but refuses and puts the gun down, shushing. He goes against the wall and sits down, crying.]

[Jake, Minerva, Fern, Martin, Susan, Frieda, Huntress Wizard, Lemonhope, Flame Princess, Shermy and Beth enter the house]

Jake: Shit, he destroyed the living room. [sees Finn crying on the floor] Shermy, come here. He's crying on the floor. Go tell him.

Shermy: Hey! Are you completely out of your mind? You destroyed half of her damn house! You shot Marceline's leg!

Finn: I know. I could've killed them. [hugs Shermy and sobs]

Shermy: [sighs] Yes. I know you did. Show them the picture and your arm. Come on, Simon. Show me your mother's room. [Simon Abadeer takes Shermy to Marceline's room] Proceed.

[Finn takes his arm off as Marceline, Princess Bubblegum, Hunson and Marion gasp and whimper.]

Princess Bubblegum: No, it can't be possible.

[Finn puts his arm back on and shows Marceline, Princess Bubblegum, Hunson and Marion the picture of the tombstone of Finn as they yelp and sob]

Princess Bubblegum: [sobbing] Oh, my God! All right, we did it. We made our son. We're really sorry we made you single and committed suicide by hanging your neck. We're also sorry we started the war.

Finn: It's all right. Now listen to me very carefully.

[the scene cuts to Finn who has a conversation with Marceline, Princess Bubblegum, Hunson, Marion and Simon Abadeer.]

Finn: Shermy and Beth came from the future. He gave me the picture of the tombstone of me as I died for being a virgin and not choosing a girl.

Princess Bubblegum: Finn, I understand.

Shermy: [checks on Marceline's leg] Deep penetration. No shattered bone. Hold here. The pressure should stop the bleeding. [Simon Abadeer holds Marceline's leg to stop her bleeding]

Finn: Thank you, Simon. Anyway, Princess Bubblegum's responsible for locking Flame Princess up as a baby. She apologized to her after I challenged Cinnamon Bun at the Fire Kingdom on my iPhone X.

Princess Bubblegum: I know, Finn. I guess you wanted Flame Princess back.

Huntress Wizard: Yes, but why'd you have Flame Princess back? Don't you love me anymore?

Finn: Of course I do, Huntress. I really do.

Flame Princess: And let me make this clear. You challenged Cinnamon Bun for me, and you punched him ugly again.

Finn: I know. If there could be a way to travel back in time... Hey. Wait a minute. That could be a great idea. Dad, you have the time machine, right?

Martin: Uh, yes. I'll tell you what, I'll take you to my time machine so you can have Flame Princess back.

Finn: Like in Back to the Future, Terminator, Bill & Ted's Excellent Adventure and Time After Time.

Martin: Yes, like in time-travel movies. Let's go.

[The scene cuts to Martin and Finn who walks to his time machine.]

Finn: Four years ago, we lost all of us. We lost friends. We lost family. We lost a part of ourselves. Today, I have a chance to take it all back. When he takes me back to the past, I'll change it so everything will change. Let's do this.

Martin: All right. To The Red Throne!

[Martin enters the keypad to travel ''The Red Throne. ''Martin's time machine flies and goes through the wormhole in the sky. The scene cuts to Finn's treehouse as text appears and says "Four years before the Gum War." The wormhole opens and Martin's time machine comes out of the wormhole from the ground and lands on it.]

Martin: Well, here we are. This is the event of ''The Red Throne. ''And here's the treehouse. Listen, if you want Flame Princess back, tell your past self. Good luck, and may the best history win.

[Finn walks to the treehouse, opens the front door, and goes inside. Inside the treehouse, Finn sees his past self looking at the Grass Sword.]

Finn: Wow, I never thought I had two arms.

Finn from The Red Throne: Oh, my Glob. Who are you?

Finn: I'm you.

Finn from The Red Throne: I can see that. How'd you get here?

Finn: I don't know, but... [looks around Finn and Jake's treehouse] I remember this. Yeah, I don't even know what else to say this, but I'm from the future. There, I said it.

Finn from The Red Throne: Really? Do I get to have Flame Princess back?

Finn: Well, I think I have an assignment just for you.

Finn from The Red Throne: Oh, yes. So, what's my assignment?

Finn: First, when you're in the dungeon before Don John the Flame Lord shows up, use your Grass Sword to pick locks.

Finn from The Red Throne: Huh. So I can use my Grass Sword to pick locks. Okay, I'll see what happens.

Finn: Good. One more thing. If you want Flame Princess back, would you find your real parents?

Finn from The Red Throne: I couldn't imagine. I wish I could see my real parents. If you wanted me to find them, that'd be a great thing. You can't do the same thing all the time or else it gets old, but every now and then, it's good to talk with you.

Finn: [smiles] Thanks. [winks and leaves]

Finn from The Red Throne: Oh, and one last thing, Finn. [Finn stops] Thanks for giving me your assignment.

Finn: Anything's possible. And you're welcome. [leaves again]

[The Fire Wolf bursts through the wall.]

Finn: Waah!

Flame Princess: Finn!

[Cinnamon Bun and Flame Princess dismount and walk over to Finn, who stands up.]

Finn: Um... [chuckles] hey. Uh, Jake isn't here. He's sleeping over at Lady Rainicorn's maybe.

Flame Princess: Finn, I've been slowly poisoned by my treacherous handmaiden. Now my powers are weakened, and—and the Flame Lord has freed my father and threatened to marry me. But I escaped with CB.

Finn: Oh, what?! I'll help you. I'll do anything for you.

Flame Princess: Listen, Finn, this doesn't mean we're getting back together. We're all business.

Finn: Mm-hmm. Of course.

Cinnamon Bun: Yeah, business.

Flame Princess: [sighs] I'm feeling exhausted. Where can I freshen up?

Finn: [points] Girls' bathroom is over there. Also, it's the boys' bathroom.

Flame Princess: Oh, thanks. [walks off]

Finn: So, what do you think, CB? You think I still have a shot with her, right?

Cinnamon Bun: [bluntly] No.

Finn: Does she ever talk about me? Is she seeing anybody?

Cinnamon Bun: No and no.

Finn: "No and no," she does talk about me, or "no and no," she isn't seeing anybody?

Flame Princess: Alright, guys, let's wolf.

[The scene switches to the three flying through the air on the Fire Wolf.]

Finn: So... your Fire Wolf can fly.

Cinnamon Bun: Yep. I taught him.

Finn: Hmm. [places his hand on Flame Princess' shoulder] Whoa! You've cooled down a lot.

Flame Princess: No funny stuff.

Finn: Things have been going great for me lately. Been hanging out with my boys. I got a cursed sword arm now, so that's new. Yeah, I've been exercising a lot and taking some piano lessons—trying to improve myself. Not dating anybody or anything, just getting a little me time, being the best Finn I can be. [scoots closer to Flame Princess]

Cinnamon Bun: [groans and looks back] Hyup! [moves Flame Princess in front of him]

Finn: Oh, no! [They reach the outskirts of the Flame Kingdom and land.] Finn: I hid my flameproof suit behind these rocks... just in case, whatever, you know?

Cinnamon Bun: [drawing in the dirt with a stick] So, the guards are posted here and here, so we should probably sneak in here. [points]

Finn: Suited! [walks over dirt drawing]

Cinnamon Bun: Uh...

Finn: Remember my fire suit? Hey, CB, you did a great job getting us here and everything, [extends grass sword] but I got this, all right?

[They walk up to the Fire Palace.]

Finn: I got a sword arm, so—

Cinnamon Bun: Yeah, you said that.

Finn: Watch this. [runs through the front door, breaking it] Hey, guards! Come at me at the same time!

Flame Princess: [hushed] What are you doing?!

Finn: Let's go, Princess! [grabs her hand]

Cinnamon Bun: But that wasn't the plan! No!

Finn: Ha-ha!

Flame Guard: [monotone] It's the princess.

Flame Guards: Capture them!

Finn: [holding up his sword] Ahhhhhh—

Flame Princess: No, Finn, don't hurt them! They're entranced!

Finn: [retracts sword] Oh, right. [Flame Guards move in on them.] Oh, no.

Flame Guards: Captured.

Cinnamon Bun: [groans angrily then roars loudly] [breaks his lance in half and runs toward the guards] Hyah! Um... [grunts] [tries to break through the guards' ranks]

Finn: There's CB!

Flame Guard: Get that bun!

Cinnamon Bun: Could you move, please?

Flame Guard: Whoo, get him, boys! We're taking these two away.

Finn: Don't worry, FP, your boy Finn won't fail you.

Flame Guard: [to Cinnamon Bun] Put up your dukes. You have permission to leave when you out-duke us.

Cinnamon Bun: Okay.

Flame Guards: Duke! Duke! Duke! [One Flame Guard swings at Cinnamon Bun and misses. Cinnamon Bun knocks the other out.]

Cinnamon Bun: Duke! Uh, duke! [hits the other one and takes one of their keys] These two are out-duked! Now I'm making my escape! [runs off]

[the scene changes to Finn and Flame Princess in prison.]

Flame Princess: [sighs]

Finn: Trust me. It'll be fine. [goes to the side and uses his sword to pick a lock]

Flame Lord: For soon you shall be mine. [chuckles] If you've forgotten, I'm reminding you now.

Flame Princess: I'll never marry you!

Flame Lord: Ah, come on now, Flame Princess. Why not? [Finn slices his horns and arms off] Hey. What happened to my horns? [his horns and arms fall to the ground] What happened to my arms? Whoa! [he falls to the ground] Ooh! Huh?!

Finn: [points his Grass Sword at Flame Lord] It's because she doesn't even know you let alone like you. And forcing her to marry you is super gross. Am I right?

Flame Princess: Uh, yes, but how did you--?

Finn: Pick the lock? Like this. [shows Flame Princess his Grass Sword as a key]

Flame Princess: Awesome!

Finn: I know, right? I just used it to dislodge a gumball in Rattleball's throat. I figured it could also pick locks. [his Grass Sword turns back, to Flame Lord] Now tell me where the king is. Talk! Or I'll slice your legs off.

Flame Lord: All right, I'll talk! He should be in the Fire Palace.

Finn: Good. [to Flame Princess] Flame Princess, I'll go after your father, just stay here and wait for Cinnamon Bun. [walks to Flame King]

Flame Princess: Like fun, Finn.

Flame Lord: Hey, are you sure you'll never marry me?

Flame Princess: Yes, I'm sure! [knocks Flame Lord out]

Cinnamon Bun: Hey, Flame Princess, I got the key... Oh. So, you already broke out. That's great, I guess. [he and Flame Princess hop on the Fire Wolf] Where's Finn?

Flame Princess: He went to fight my father.

Cinnamon Bun: That... was actually part of the plan.

Flame Princess: But he's gonna need our help.

Cinnamon Bun: All right.

[The scene cuts to Flame King in the royal chamber]

Flame King: Wow, I love looking out overstuff.

Finn: Enjoy it while you can, Your Majesty. And that's why you're locked up in the lamp with Don John.

Flame King: What? You're still here? How'd you break out of prison? She doesn't even love you anymore!

Finn: Keeping her safe is more important now. And because she's worth it.

[Finn shouts and Flame King growls while they charge then Finn slices Flame King's sleeves]

Finn: That was awesome.

Flame King: [his sleeves fall off] Oh, no.

[Flame Princess and Cinnamon Bun enter the Fire Palace while they ride on the Fire Wolf]

Flame Princess: Finn, wait for-- [sees her father sleeveless] Oh! Oh, dear!

Cinnamon Bun: Look away, Princess.

[Flame Princess and Cinnamon Bun look away. The scene cuts to Flame King and Flame Lord in the lantern.]

Flame King: I've never been very humiliated.

Flame Lord: I know. He cut your sleeves off.

[The scene cuts to Cinnamon Bun and Flame Princess.]

Cinnamon Bun: I guess I was wrong.

Flame Princess: About what?

Cinnamon Bun: About Finn. I guess he really is the hero you deserve.

Flame Princess: I think you're right.

Cinnamon Bun: Then you should tell him before he leaves.

Flame Princess: [touches Finn's shoulder] Finn, wait!

Finn: Yes, Flame Princess?

Flame Princess: Look, about what I said earlier about us not getting back together, I change my mind. I mean, sure, you've been acting immature at first. But then you actually put your feelings aside long enough to complete the mission. [hugs Finn] So, yes. We're now both getting back together.

Finn: I love you, Flame Princess. [hugs Flame Princess]

Flame Princess: I love you, too, Finn.

Fire Citizen: Aw, that's nice.

[Finn and Flame Princess walk to the throne chair as she sits then the Fire Citizens cheer. Flame King yells in frustration.]

Cinnamon Bun: Wow. I guess they're officially back together now.

[the scene goes to Finn and Martin outside the Fire Kingdom]

Martin: That's wonderful, son. Now you're married to Flame Princess.

Finn: I did it! I stopped Marceline and Bubblegum's war and prevented to create a paradox.

Martin: Yep. [vanishes from his existence] I guess.

Finn: Yeah, I don't know. [vanishes from his existence along with the time machine] Maybe this wasn't the greatest plan.

[the scene fades to black and text appears and reads "On Finn's 21st birthday..." then the scene fades to Finn who stands outside. The door opens and Flame Princess walks to him.]

Flame Princess: Happy birthday, Finn.

Finn: Thanks, Phoebe.

Flame Princess: Come inside, your parents are here.

[Finn walks inside and sees his parents.]

Martin: Happy birthday, son.

Finn: Thanks, Dad. And you're right. The history's changed, I still have my arm, and you brought me Dr. Gross... [Dr. Gross waves her hand] Shermy, Beth, and all these gifts your wife sent me. Thanks, Mom.

Minerva: You're welcome.

Finn: Also, I created my grass clone, Fern.

Fern: Hello.

Finn: And I also invited Huntress Wizard, Cinnamon Bun, Susan Strong, Frieda, Lemonhope, Sweet P, Tree Trunks, Mr. Pig, Tiffany Oiler, Patience St. Pim, Simon Petrikov, Ice Thing, Bun Bun, Princess Bubblegum, Marceline, Aunt Lolly, Simon Abadeer, Hunson, Marion and even Steve Buscemi.

Steve Buscemi: Damn, that's a lot of people you wrote on the list. So, thanks for inviting us all.

Finn: You're welcome, Mr. Buscemi.

Steve Buscemi: Please, call me Steve.

Finn: Oh! They're about to light 21 candles. Frieda, go dim the lights. [Frieda dims the lights] All right, one, two, three.

All: [singing] Happy birthday to you

Happy birthday to you

Happy birthday dear Finn

Happy birthday to you

[Finn and his family cheer.]

Frieda: Now, blow out the candles and make a wish.

[Finn closes his eyes and blows out 21 candles. Finn's family applauds. The scene goes to the Prismo's Time Room as Cosmic Owl bangs his gavel.]

Cosmic Owl: I now call this an emergency meeting to the characters from "Team Fortress 2" to order. I, Cosmic Owl, the greatest guardian in the universe of all time, have summoned here today to due the troubling situation.

Demoman: I believe Bandit Princess is missing, Cosmic Owl.

Sniper: Finn got Flame Princess back together, my lord.

Heavy: I've know that Finn's responsible for traveling back to the past with his father, Martin Mertens.

Soldier: The infinite possibilities have created one giant possibilities.

Pyro: Uh-huh.

Cosmic Owl: Very good. And Scout?

Scout: It would appear Finn used illegal time travel to create a paradox and destroy his own universe, my lord.

Cosmic Owl: And Engineer, why was Finn willing to destroy his own universe?

Engineer: To stop the war, Cosmic Owl.

Medic: I'm concerned that the infinite universes create one enormous multiverse.

Spy: As you know, the time travel situation seemed strange and bizzare.

Cosmic Owl: Oh, Glob. Okay, let's do something about those characters. And for now, Prismo, I need you to rebuild and repair the most recently destroyed universe as it was before the time travel fiasco.

Prismo: As you wish, Cosmic Owl. Finn's universe shall be rebuilt, repaired and returned.

Cosmic Owl: Let's rebuild it.

[the scene goes to clips from seasons six, seven, eight, nine and ten then fades to Finn and his family who are now reappeared in their own existence.]

Finn: What the... Hey, we're alive again.

Marceline: Of course we are. And nothing's changed.

Shermy: Huh. I never thought that Finn's own universe was repaired and anything never changed. Do you think we should go home now?

Finn: Uh, sure.

[Finn and his family walk home. At Finn's house, Finn opens the door and turns on the light switch then he sees Dr. Gross, Tiffany Oiler and characters from "Team Fortress 2" as the song plays "Burn It to the Ground" by Nickelback.]

Dr. Gross, Tiffany Oiler, Scout, Soldier, Pyro, Demoman, Heavy, Engineer, Medic, Sniper, Spy, Miss Pauling: Surprise! Happy 21st birthday!

Finn: Whoa! You're the characters from "Team Fortress 2" known as Scout, Soldier, Pyro, Demoman, Heavy, Engineer, Medic, Sniper, Spy and Miss Pauling.

Miss Pauling: That's right. It turns out that there are infinite universes creating one giant multiverse. Sometimes we're good, sometimes we're evil, sometimes we're toys, or movies, or TV shows, or merchandising, in the multiverse, it's all canon.

Finn: Oh, my Glob. But if you're from Team Fortress 2, why are you actually here in Ooo?

Cosmic Owl: Because we brought them here.

Finn: Cosmic Owl, is that all true?

Cosmic Owl: When your timeline was altered, I brought Fionna, Cake, Flame Prince, Lord Monochromicorn, Prince Gumball, Butterscotch Butler and Marshall Lee.

Fionna: Hey.

Finn: What in the name of God is happening?

Cosmic Owl: Since their universes are long gone and they have no place to go, we gathered them to let them stay in Ooo with you while we wait for Merasmus.

Finn: Wait for Merasmus? Where's Merasmus?

Merasmus: I'm standing right behind you.

Finn: Oh. So, those are our gender-swapped counterparts.

Marshall Lee: Yep. We're ready to kick ass and we're excited to get a new home.

Finn: So what's your story, Flame Prince?

Flame Prince: My story is to beat up villains.

Cosmic Owl: Finn, you must make love to Flame Princess in the bedroom. The gods can no longer make exceptions for you under circumstances. If you die a virgin, any of you it'll be permanent. Now, go. Take your counterparts and save your universe.

Finn: No problem, Cosmic Owl. Hey, Phoebe.

Flame Princess: Yes, Flame Princess?

Finn: I have one thing to say. [shows Flame Princess the wedding ring] Will you marry me?

Flame Princess: [gasps] Oh, Finn, that's really sweet of you. Of course I'll marry you.

Huntress Wizard: Wait a minute. So you're saying that Flame Princess has to marry you, and you're okay with this?

Finn: Yes.

BMO: Oh, that's good to hear.

Finn: Dr. Gross, you came here in Ooo, and then you could take revenge on us. What, were you actually gonna turn people into a cyborg army?

Dr. Gross: Yes. But it's different now, Finn. I made a decision to stay.

Finn: Wow!

Dr. Gross: On my island, I'm just kind of a virgin like you, but here, the Land of Ooo has humans. I'm getting to like it right here.

Finn: Oh, I see. When it comes to annihilation, everything would've been random. And you know what? Your work will be responsible for the extinction of humanity.

Dr. Gross: You're right, Finn. My work was responsible for the extinction of humanity.

Flame Princess: Finn, I have something to say to you. Sorry about that break-up. I didn't think about Bubblegum erasing my memory, or about you having to pay the price for a choice you never made. It's not fair, I know. And then, I made it worse at Marceline's house by trying to... Anyway, anyway. I'm sorry. I'm used to knowing what the right thing to do is, but now I'm not sure anymore. I just wanna be... [sighs] I just wanna be a good princess.

Finn: [walks to Flame Princess] You're not good. [hugs her] You're hot.

Flame Princess: [chuckles] Thanks, Finn.

Finn: You're welcome. Anyway, let us take a selfie!

[Finn takes selfies with Flame Princess as they eat neapoltian cake and open presents for Finn while the song plays "Selfie" by The Chainsmokers.]

Flame Princess: So, what present do you have?

Finn: I have a new arm with new fingers and new abilities.

Flame Princess: Very nice. And what else?

Finn: A brand new katana.

Flame Princess: Incredible.

Finn: So what do you say? Wanna make some love?

Flame Princess: Oh, Finn, of course I do.

Finn: If you'll excuse me, I'm gonna need privacy with Flame Princess.

Jake: Sure, bro. Go for it.

[Finn and Flame Princess walk to his bedroom. At Finn's bedroom, Finn and Flame Princess have sex while the song plays "Human Connect to Human" by Tokio Hotel. After the song ends, Finn and Flame Princess fall asleep on his bed.]

Flame Princess: Wow. That was awesome. Honey, I just want you to know that I love you.

Finn: Yeah, I love you, too.

Flame Princess: Now that we're back together, I guess you're the greatest person I've ever known.

Finn: Yes. Well, I guess with the way you enchanted me, I'm gonna guess you are evil.

Flame Princess: Hey, now. You took initiative too.

Finn: Well, yeah, I had to defeat the evil in you and cleanse you inside out.

Flame Princess: I'm pretty sure my insides are dirtier than ever. And you're right, Finn. With this much semen, I might be pregnant.

Finn: Maybe that's what I want. [Flame Princess chuckles] Anyway, put your clothes back on.

Flame Princess: Sure thing, honey.

[Finn and Flame Princess move out of his bed and put their clothes back on.]

Finn: Now we're ready for the last battle. And then humanity will finally be at peace.

Flame Princess: What do you mean, the last battle?

Finn: Means the truth will be revealed. [opens the bedroom door]

Engineer: Y'all know what this means, right? [presses the red button and the screen shows the destroyed city] I took a picture of the city where Marceline lived there as a child and she discovered Simon Petrikov. The villains could appear in there and now is the time to kick their asses. And another thing, you've got backup, partner.

Finn: That's right, Engie. Gather your weapons. We're going to the city. Whatever it takes.

[The scene cuts to Finn and his family who pick their weapons for their final battle while the song plays "Bangarang" by Skrillex then cuts to Bandit Princess who lives in the cockpit and sees Dr. Gross and Tiffany Oiler on screen and the song ends.]

Bandit Princess: Dr. Gross betrayed us? How did you let this happen? Set a course for the grass plains and prepare for battle!

[The scene cuts to the city as the ground rumbles then Dr. Gross's rocket comes out of it. The scene cuts to Bandit Princess in the cockpit and she looks at the city.]

Bandit Princess: Finn Mertens, come to me.

[The scene cuts back to the city as Finn, Flame Princess, Huntress Wizard, Fern, Jake, Minerva, Martin and BMO arrive then Flame Princess turns on the live camera.]

Finn: Attention, Land of Ooo, my name is Finn Mertens, son of Minerva Campbell and Martin Mertens. I was born on Founders Island and raised in here. I had great quests, friends, and even a tree house. Four years ago, the Great Gum War was a complete success after GOLB arrived and granted a wish from Betty Grof. And now, a new threat happens in Ooo. Dr. Gross came back for us with Tiffany Oiler to plot revenge on us. Well, I say it's wrong. Dr. Gross decided to stay with us. I made love to Flame Princess after I fought Cinnamon Bun. Bandit Princess murdered Box Prince and stole a large sack of coins. She survived GOLB and avoided talking to the Ice King. Along with Ash, Peace Master, Sir Slicer, Me-Mow, Samantha, Pete Sassafras, Ricardio, and Scorcher. Ask yourselves! Are you ready for the final battle? Are you ready to fight? I'm Finn Mertens. In the name of my parents, in the name of Jake, we ask you to join us on the grass plains. In the name of my friends... [raises his fist in the air] help us save the Land of Ooo.

[Flame Princess turns off the camera and Finn puts his fist down. Bandit Princess sees Finn, Flame Princess, Huntress Wizard, Fern, Jake, Minerva, Martin and BMO stand. The door whooshes open and Bandit Princess comes out of Dr. Gross's rocket.]

Bandit Princess: Well, I guess you turned back time and changed the past. And here we are, nothing's changed. [to Huntress Wizard] You know what's sad? If it weren't your core beliefs, I think we could've been good sisters.

Huntress Wizard: [scoffs] At least I have core beliefs.

Bandit Princess: [to Finn] The relationship with Flame Princess seems ruined. You'll never marry Flame Princess ever.

Finn: Never?

Bandit Princess: [snickers] No. And you know what? Things seem really silly.

Finn: And you know what else? You're under arrest for the murder of Box Prince and for stealing a large sack of coins.

Bandit Princess: Is that so?

Finn: Yes.

Bandit Princess: We'll see about that. I'm gonna enjoy destroying each and every one of you!

[Finn, Flame Princess, Huntress Wizard and Fern fight Bandit Princess until she strangles Fern.]

Bandit Princess: You should've belonged to Gumbald's Legion of the Candy Kingdom Haters. [Fern conks her head]

Fern: I turned to good side and Gumbald turned back into a punch bowl.

Bandit Princess: [groans] I think I have some backup.

Finn: Yes, I can hear you. [a portal opens]

Simon Abadeer: Thev've really got shit you've never seen.

Finn: What does that mean? What are our chances?

Simon Abadeer: Well, pretty much zero.

Finn: You're right, Simon. We're going after the Legion with everything we've got.

[Finn wears the fire armor and uses the jetpack. Finn and Simon Abadeer fly to Dr. Gross's rocket. In Dr. Gross's rocket, Finn and Simon Abadeer land on the floor as they confront Bandit Princess, Me-Mow, Ash, Sir Slicer, Scorcher, Samantha, Pete Sassafras, Peace Master, and Ricardio.]

Bandit Princess: Finn, surrender now.

Finn: No. We won't let you destroy the Land of Ooo.

Bandit Princess: Then die.

[Bandit Princess draws her sword. Simon Abadeer grunts and duels Bandit Princess. Finn duels Ash and conks his head. He runs to the laboratory. In Dr. Gross's laboratory, he opens the door and hides under the desk.]

Finn: Good thing no one would find me here.

[Ash opens the door.]

Ash: I can see you from here, son. [uses the M16 rifle with laser sighting and he shoots but misfires] Never should've traveled back in time.

Finn: You should've never came after my family.

Ash: Tough luck, Mertens. I'm still Marceline's boyfriend.

Finn: Yeah, but Marshall Lee's gonna be Marceline's new boyfriend.

[Ash scoffs and draws a knife. Simon Abadeer enters.]

Finn: You're the princess who killed Box Prince.

[Finn duels Bandit Princess. The scene goes to Simon Abadeer who confronts Sir Slicer in the examination room.]

Simon Abadeer: Sir Slicer.

Sir Slicer: Simon Abadeer.

Simon Abadeer: I guess you survived GOLB after Gumbald was defeated by the rock, huh?

Sir Slicer: Yes, that's right. I survived GOLB.

Simon Abadeer: Listen, I think we've gotten into the wrong hands. I'm the son of Marceline. Uh, let's talk music. Do you like the Metallica song "Master of Puppets"?

Sir Slicer: I don't like heavy metal shit.

Simon Abadeer: Oh, you don't. Oh. Okay. Well, I only bring it up because, uh, it's you. You're the Master of Puppets.

[Finn duels Bandit Princess. The scene goes to Simon Abadeer who finds Finn and sees Ricardio who uses his M16 rifle. Simon lands on the rooftop, comes at Ricardio then slices him up.]

Simon Abadeer: You're halfhearted, that's good. Amen.

Me-Mow: No! Impossible! They're too powerful and too strong!

Simon Abadeer: Hey, kitty!

[Simon Abadeer duels Me-Mow until he decapitates her.]

Simon Abadeer: I hate talking female cats. No offense, Cake.

Cake the Cat: That's all right.

[The scene goes to Finn who duels Bandit Princess in the hybrid animal room then he knocks her out.]

[Simon Abadeer sees Finn and hugs him.]

Simon Abadeer: Finn. You're all right.

Finn: Come on, let's go after Samantha.

[Finn and Simon Abadeer go after Samantha. The scene cuts to Samantha who sees Finn and Simon Abadeer where they come at her then she walks backwards.]

Samantha: Finn, listen to me, none of this is my fault. You see, Gumbald poisoned my mind. Turned me against you. [chuckles nervously] I loved your treehouse. No, stop. I'm ordering you to stop! I mean it! You took Gumbald away from me! You swore to the war! Wait, wait, wait, wait. [chuckles] You fight for money. I have plenty of money. Name your price. Find it in your heart to forgive.

[Finn grabs Samantha by the neck.]

Finn: You want forgiveness?

[Finn throws Samantha to the wall and stabs her in the heart with his katana sword. Samantha chokes weakly.]

Finn: Ask my family for forgiveness.

[Samantha lets out her dying sigh. Chains strangle Finn and Peace Master pulls then Finn falls to the street.]

Peace Master: I've never killed a human before.

[Peace Master tries to kill Finn but gets stabbed in the back as he groans and dies. Shermy removes the Finn Sword from Peace Master's back and sighs.]

Shermy: Nobody tries to kill my ancestor.

Finn: [stands up and shake hands with Shermy] Well done, Shermy.
