(The episode starts in the Tree Fort, where "Incendium" ended. Its last six lines start this episode.)
Flame Princess: Don't ever mess with me again!
(Flame Princess shoots out the window in a trail of fire)
Finn: (Looks at Jake) Who was that?
Jake: (Still terrified) The Princess of the Fire Kingdom?
Finn: (Looks out the window, then back at Jake) Dude, I think I have a crush.
(Finn walks in front of Jake)
Finn: What do you know about her, Jake?
Jake: I was trying to help you get over your Princess Bubblegum sad times by hooking you two up. But she's evil, man!
Finn: You shut your dirty mouth! (Slaps Jake. Finn's angry outburst causes the burn mark to disappear)
Jake: Dirty? (Checks gums) Oh. No, really man! Her dad said she was evil!
Finn: Naw, man, I peeped beyond her burning gaze, and noshed hot lunch with her soul. (Walks to the window) She ain't evil. She's passionate. Help me track her down.
Finn: C'mon, man, I really like her. Help me out. (Rubs Jake's face) Jake, Jake help me out. Help me out. Jake, Jake, help me. Jake, Jake, help me!
Jake: Eeeeeeeeehhh, ok.
Finn: Whoo! Alright!
(The scene cut to Jake walking over trees as a giant with Finn on his head.)
Jake: You sure you're not into any other princesses? What about Wildberry Princess? She's small and plump. You could sleep on her like a pillow. Could be nice.
(Light shines on Finn and Jake as a burning bird flies away.)
Finn: Is that bird... smoking?
Brown Bird: Hey, don't you judge me. It was that fire chick down there that done this to me.
(Jake stretches down the bushes as he and Finn hide behind them. They see Flame Princess touching flowers and burning them)
Flame Princess: Oh.
(The fire burns other flowers, spreading towards a lake.)
Flame Princess: (Gasps)
Finn: Oh, Jake... look at her. She's innocent. Like the steam off a puppy's nose, searching for ham in the snow.
Jake: Guy drops one piece of ham in the snow and he never hears the end of it! Snap out of it! She's burning cute little flowers!
Finn: (Focusing on Flame Princess) Yeah, she is like a cute little flower.
(Flame Princess walks towards the lake, kneels and dips her hand in it)
Flame Princess: Aaahh!
Finn: (Comes out of the bush) Oh, no, are you ok?
Flame Princess: (Gasps)
Finn: I... I was just worried about you.
Flame Princess: Huh?
Finn: Look, I'm sorry about what I said before. I don't know what happened, but I just, I had to see you again. And, I don't know.. I don't know anything about you, (Flame Princess glows brighter) but I just, I really like you. You know, you're so... beautiful.
(Flame Princess glows brightly)
Finn: (Sees fire beneath him) Whoa!
(Finn stomps on fire, but stops when he sees Flame Princess reacting with pain.)
Flame Princess: Ah!
(Finn stomps on fire again)
Flame Princess: Ow!
Finn: Oh, Glob. Am I hurting you?
Flame Princess: Yes! That's all you've done! (gasps) Are you trying to hurt me?! Is that why you're following me?!
Finn: I'm not followi-- Well, I guess technically I am following you.
Flame Princess: (Gasps then runs away)
Finn: Hey, no wait! (Chases Flame Princess)
Finn: (Laughs awkwardly) I guess now I'm technically chasing you. (Laughs again)
(Jake comes out of the bushes)
(Flame Princess burns tree. Tree falls down, blocking Finn and Jake)
Jake: Hold on! (Turns into a giant and uses his "buns" to put out the fire on the tree)
Jake: Eaoww.. Toasty buns. (Runs off while carrying Finn as they reach the end of the forest)
Finn: Where are you? I want to chat it up with you! Oh, we lost her!
(Flame Princess appears as trails of fire then reforms)
Flame Princess: I am ambushing you! (Throws fireball)
Finn and Jake: Aah!
(Finn and Jake run around to avoid fireballs)
Finn: Hey, I like your fireballs.
Flame Princess: Huh? Why do you torment me?
Finn: I'm not trying to. I just like you. I think I... I think I like-like you. Listen, when I look at you, my brain goes all stupid. And I just wanna hug you, and sit on the couch and play BMO with you. I can't explain why, but, I never felt this way before and I think we should be together.
Flame Princess: I... (Smiles, blushes and glows brightly)
Finn: (Smiles, claps, and laughs in excitement) Yeah.
Flame Princess: Rggh! Enough. You should not toy with the emotions of a fire elemental.
Finn: Wait wait, I really didn't--
Flame Princess: You told me you liked me, and you made my flame grow brighter, but then you put me out, which hurt! (Throws a big fireball at Finn and Jake)
Flame Princess: You're trying to impede me. That must be your purpose, ...but fire's purpose is to burn, so I'm going to turn this land into my fire kingdom!
(Flame Princess creates a fire wall as Finn and Jake back away from the fire)
Jake: She's headed for Goblin Kingdom! We need to defeat this fiery she-beast!
Finn: I can't fight her, man. I'm still into her!
Jake: Finn, what's more important? Your love for that screwball dame, or being a hero and savin' the lives of innocent goblin folks?
Finn: Rrrrhh.. Being a hero.
Jake: Alright, c'mon! Let's go build fire-proof suits.
(Scene cuts to the Tree Fort's garage.)
Finn: (Frantically searching pile of junk) Uh-uh-uh, I gotta' get back to her.
Jake: Dude, slow down or your fire suit will be junk. (Sees a bag of bread) Ooh. Is bags of old bread fire-proof? (Slightly shoves the bag, showing NEPTR.)
NEPTR: Jake, you've found NEPTR! I am the ultimate hide-and-seek champion! 15 months, 4 days, 9 hours and you guys did not find me! (Spins his oven body) Hahahaha-hahaha.
Jake: (Whispers to Finn) Oh, plops, we forgot about the game.
NEPTR: I missed you, creator.
Finn: And we missed you, too, but NEPTR, right now we need you to--
NEPTR: To count to 100 while you hide? 1, 2,.. 3, 4, 5--
(Finn halts NEPTR)
Finn: NEPTR, will you help us build fire-proof suits?
(NEPTR raises his arm)
NEPTR: You cannot tell but I am giving a thumbs up.
(NEPTR raps "Working for the Master" as he builds Finn and Jake fire-proof suits while the two assist him)
NEPTR: I am finished!
(The scene cuts to Finn flying with his suit.)
Finn: I sure hope Flame Princess is okay.
NEPTR: Haha, we are as one, creator.
Finn: Jake, you think Flame Princess is okay?
(Jake rises up as Finn spins to avoid Jake)
Jake: DUUUUDE! I feel like I can touch the heavens! (Whispers) And sock angels!
Finn: We're coming up on the Goblin Kingdom.
(Finn and Jake fly above trails of fire as they see the kingdom)
Finn: There she is.
(Flame Princess shoots fire on houses)
Finn: She seems okay.
Goblin: AAAAHH! Wood for sale! Wood on fire for sale!
(Flame Princess shoots out two lines of fire and turns around)
Flame Princess: It's really starting to come together. Needs more... fire... hmm.
Finn: Flame Princess!
(Flame Princess turns)
Finn: Listen, you gotta stop burning the Goblin Kingdom, ...but I don't wanna fight you or hurt you, I swear.
Flame Princess: I've heard this all before. (Shoots fireballs at Finn and Jake but their suits put out the fireballs. They land in front of Flame Princess)
Flame Princess: You... MEANIE! (Throws fireball at Finn. The suit deflects the fireball as the latter bounces. Hitting a goblin's cart.)
Goblin: My cart. I was born in that cart!
Jake: (Gasp) I'll put it out! (Jake runs through cart and crashes into a building.)
Flame Princess: Ah!
Finn: Aah! Jake didn't mean that!
(Flame Princess shoots a stream of fire at a building.)
Jake: Oh... (Hovers near the fire.) I need your help Finn! This one's too big! (Kicks fire)
Flame Princess: Ah! Whyyyy?!
Finn: No, Jake, stop. You're hurting her!
NEPTR: I will solve this, creator. I will extinguish her using our suit! Foam blaster. (NEPTR raises the suits right arm and retracts the hand into a blaster.) Hold still, burning lady.
(NEPTR turns the suit around and aims the blaster at Flame Princess)
NEPTR: Locked on target.
Finn: (Finn holds the blaster with his suit's left hand) No, NEPTR!
NEPTR: Yes, creator.
(Finn turns the suit around, before the blaster fires)
(The blaster hits Flame Princess's fire)
Flame Princess: AH!
Finn: (Distressed) I'm sorry!
(NEPTR lowers the right arm down, hitting Jake with foam as his suit is covered by it.)
Flame Princess: That is the last time you hurt me. (Transforms into her giant form) RAAAAAAAAAAAAAHHH!
Finn: My bad, Jake! Turn it off, NEPTR!
(Finn turns to look at Flame Princess)
NEPTR: Oh, my...
(Flame Princess turns around and burns the whole city.)
Flame Princess: RAAAAAAAAAHH! (A "tear" comes out from Flame Princess's right eye.)
Finn: No more... No more! (Kneels the suit then rips out of his suit and climbs at its top.) FLAME PRINCESS!
(Flame Princess walks away)
Finn: I can't fight her, ...but I can't let her destroy the city... I've failed everyone.
NEPTR: Not true, creator. You haven't failed NEPTR. Even if everyone burns, you'll still have me, creator.
(Finn looks at Jake, who is moving his own suit's limbs. Jake takes a scoop of the foam and eats it.)
Jake: Mmm! (Smiles and gets another scoop.)
Finn: No. Why can't I just like a girl? (Finn's tear drops onto Flame Princess's fire.)
Flame Princess: Ow! (Looks angrily at Finn. She notices he's crying.) Huh?
(Dives as a fire towards Finn while she shrinks her size.)
Finn: (Coughs then faints.)
Flame Princess: (Touches Finn's tears then jumps back) Oh.
(Flame Princess puts all of her fire out.)
Finn: (Gasps for air then coughs; he sees Flame Princess by his side.) Wah! Did I... do something... cool while I was knocked out?
Flame Princess: I understand now. You're a water elemental.
Flame Princess: You're my opposite. You create water.
Finn: What, cry? No, I j--
Flame Princess: Yeah, you cry and cry all the time.
Finn: N-No. I-I don't usually do that.
Flame Princess: That's your power.
Finn: No! N-N-N-NO-NO-NO! (waves his hands while blushing.)
Flame Princess: Finn, even if we like each other, we're going to hurt each other.
Finn: No, we don't have to. I can take it... I... I mean, can't we try?
Flame Princess: You would defy nature for me?
Finn: Uh... yeah, whatevs.
(Finn and Flame Princess hug, Finn tries to bear the pain but pulls away.)
Finn: Aaah.. Uh.
Flame Princess: Bye, Finn. (Departs)
NEPTR: Goodbye, lady.
Jake: FINN! (Stretches up.) Oh my Glob, man. Everyone's dead, man! They're all burned. There's barbequed bods EVERYWHERE!
Jake: Hah. I'm just kidding. I saved 'em. Everyone's fine, see?
(Jake gestures towards the crowd of unharmed goblins)
Jake: So. How'd everything go with Flame Princess?
Finn: She hugged me... then left.
Jake: Whoa! How did it feel?
Finn: (Turns to the direction Flame Princess took while leaving a trail of fire behind.) It hurt.
