Hot to the Touch

"Hot to the Touch" is the First episode of season four of Adventure Time.

Synopsis
Finn's quest to prove Flame Princess isn’t really evil and to win her heart turns into a quest to stop her from taking over the Goblin kingdom.

Plot
The show begins right before the episode "Incendium" left off with the Flame Princess telling Finn to never mess with her again, slapping him in the face, then leaving. Jake then explains that he was trying to help Finn get over his "Princess Bubblegum sad times" but then explained that she was evil. Finn became extremely mad at Jake for saying she was evil and claimed he "peeped beyond her soul" and that she was, in fact, not evil. Finn then convinces Jake to help him track her down.

Jake begins to walk over the forest with Finn and try and convince him to date another princess and even suggests Wildberry Princess as an option. Suddenly a Brown Bird flies above that was set on fire by the Flame princess and directs Finn and Jake to the location of the Flame Princess. Jake then shrinks down and him and Finn starts to spy on flame princess. They view flame princess curiously playing with and burning a few flowers while spying on her and both of them continue to argue about whether or not she is evil while they are watching her, but the conversation is stopped abruptly when flame princess hurts herself by putting her hand in a puddle of water.

Finn blows his cover just to see if Flame Princess is alright and tries to explain how he feels, but Flame Princess refuses to believe that Finn was trying to help her and thinks that Finn is only trying to hurt her because he was responsible for putting out some of the flames that she created. This is nonetheless true, and when Finn got scared of the fire that creeps too close to him, he puts it out, and it is revealed that destroying the fire that Flame Princess created actually causes her physical harm. She gets scared and runs away and Finn chases her and Jake follows Finn into an open field where Flame princess ambushes them.

The attack does not last long and Finn confuses Flame Princess by trying to compliment her while she is trying to kill them. She then explains that all Finn has done is hurt her and that she thinks that Finn is trying to apede her and to take revenge she is going to turn the Goblin kingdom into her very own personal fire kingdom and starts putting the entire field ablaze. Finn and Jake manage to escape and Jake tells Finn of his plan to build fire proof suits. Finn and Jake return to their tree house and go into the garage in attempt to find some raw material to build their suits but instead find NEPTR who was playing hide and seek and claims he was hidden for over 15 months, 4 days, and 9 hours, NEPTR then helps build fire proof suits for Finn and Jake to wear. The suits are huge metal robot like shells equipped with rockets and a foam blaster and are fire proof (and NEPTR is actually a part of Finn's suit).

They all fly to the goblin kingdom where they try and reason with Flame Princess but she continues to rampage and tries to attack Finn and Jake, but it doesn't work because the suits are fireproof. Jake then attempts to put out some of the fires and hurts FP in the process then NEPTR attempts to put out FP by blasting her with the foam cannon but Finn manages to stop NEPTR from directly hitting flame princess and instead he hits jake and a few of FP's flames. Flame Princess then gets extremely angry and proclaims "that is the last time you hurt me" and grows into her beast form and continues to rampage through the goblin kingdom.

Finn then literally rips himself out of his own suit and stands on top of it and shouts to Flame Princess but she ignores him and Finn says he failed everyone but NEPTR says "master hasnt failed NEPTR ." Finn begins to cry and some of his tears fall on the flames of fire princess and not only hurt her, but catch her attention. Flame Princess watches Finn cry for a little then stops all her flames from destroying the city and says she thinks she understands now and that Finn is a water elemental because he creates water (cries). Finn tries to explain that he isn't but Flame Princess has trouble understanding the concept and says even if they liked each other, they would only hurt each other. Finn says they could try, and hugs her but finn gets burned and begins to tear up again so Flame Princess says goodbye and leaves. Jake then goes over to comfort Finn telling him he saved all the goblins and asking how things went with flame princess. Finn tells Jake "she hugged me, then left" Jake replies "Whoa, how did it feel?" and Finn ends the episode with the line "it hurt." thumb|right|285px|Animaticthumb|right|285px|Long Preview
