The Comet

Synopsis
After Orgalorg reveals its true, gigantic form, Finn and Jake are jettisoned into space and separated.

Plot
After Princess Bubblegum notices the purple sky and the explosion from the Candy Kingdom, Peppermint Butler spots her spaceship emerging through the smoke. Finn and Jake cling on to the rocketing ship. They slip from the top but Finn's thorn on his hand catches hold of the ship. When inside, they find spacesuits, put them on and try to stop Gunter. Gunter is already outside of Earth’s gravity and the green brain peels away to reveal his true form, replacing the penguin with its true form as Orgalorg.

The fully-powered Orgalorg destroys the spaceship and takes on a larger form, similar to a jellyfish. It talks to Finn and Jake about opening doors that allowed him to do what he wanted. Jake empathizes with Orgalorg about his philosophy until Orgalorg reveals he wants to destroy planets. He snatches up and sends Finn and Jake careening through space, putting Jake on the path to the croak dream he had back in season 3’s “The New Frontier”. Finn is floating alone in the void of space, he dedicates all his power to merging his intentions with the universe through a meditative song. He sings about how things are falling into place and he’s exactly where he needs to be, and he achieves serenity by fully believing these words. The universe responds to this belief by making it true, and Finn ends up being exactly where he needs to be: right in the flight path of Martin’s giant glowing moth.

Finn asks to be helped but Martin insists that the Moth does what it wants and can't be controlled to help Finn. Martin pulls out a pair of underwear and assures Finn that he'll be fine since he's wearing gloves. Finn gets into the moth's mouth with Martin hoping to stop Orgalorg with his dad and the moth, but his dad explains that he can't control the moth as it goes where it wants and begins to panic as he hears Orgalorg's name. He claims that he isn't dumb and know who Orgalorg is, hinting at Orgalorg's existence to be common knowledge for some. Suddenly, the moth starts to fly toward Orgalorg. The Catalyst Comet gets consumed completely by Orgalorg. Finn jumps out of the moth's mouth and dives into Orgalorg's mouth.

Inside he hopes to free the comet, which is being drained of energy by tentacle-like branches from inside the monster's mouth. The branches also attack Finn, penetrating through Finn's arm, causing his grass hand to evolve, which bursts out of his spacesuit into a whiplike vine appendage. Using this vine arm, Finn cuts the comet free, and slashes several slits through Orgalorg, causing an ejaculation of cosmic power that contains the promise of new life if Finn accepts it. The seed of this change is the purple three-eyed sphere that is the comet’s core, and it offers enlightenment to Finn, showing him his past life as one of the incarnations of the comet. The comet became a butterfly and many other things including the Lich, as was previously revealed in "The Vault." All of this leads to Finn in space at this exact moment, choosing if he wants to go with the Purple Comet to “the end and beginning” or if he wants to stay a human back on earth.

“This is your crisis,” says the Purple Comet as a rainbow radiates from Finn’s head, projecting images to accompany all the words in the forthcoming list. “As you stand on the edge of freedom from love, hate, friendship, isolation, jealousy, secrets, violence, video games, ice cream waffles, sadness, madness, power, honor, loyalty, saucy, mothers, fathers, scoundrels.” Finn cuts the comet off and asks how long it's going to keep listing things, but the comet replies that it's a very long list. That's because a life is made up of a million and more different things: relationships, emotions, possessions, experiences and many others.

Finn points out that is not making that option sound bad, and the comet answers that it's not supposed to be; the comet continues by saying that it is just giving Finn the choice of a new existence. Finn says that he's put a lot effort in his "meat existence" and would like to see it through to which the comet is content with Finn's choice. Martin, on the other hand, is excited for the future, and would love the chance to enter a new mode of existence. Finn is initially disappointed that his father is going to run off again, but he finds comfort by realizing that Martin was never going to change and that this ultimate act of abandonment is what his father's life has been leading to and Martin is "glad" that they "finally understand each other." And then Martin asks the comet to "start the engine" and Martin and the Moth are gone, transported by the Purple Comet to a new state of being while Martin biding his son farewell.

Finn finds Jake's suit but gets terrified when he doesn't find him in it. Jake suddenly appears with Banana Man in his rocket from the back. They ride it back to Ooo. Orgalorg's remaining form grasps on to the rocket ship with his tongue as it speeds into the earth's orbit. Orgalorg gets compressed by earth's gravity and gets crushed back into Gunter. The rocket crashes into Lake Butterscotch where Princess Bubblegum and Peppermint Butler observe from the side next to their cabin. Finn, Jake, Banana Man and Gunter emerge from the ship unharmed and satisfied. Peppermint Butler is holding a fish that was flown out of the lake as the rocket crashed. The fish claims that it'll croak now.

Trivia

 * This episode reveals that Finn is 16 years old.
 * Orgalorg is still alive after the events of the episode, despite being sliced by Finn and burst by the Purple Comet. Orgalorg is also able to fully compress into Gunter despite massive injury and loss of flesh from the exploding comet.
 * It is revealed that the thorn in Finn's right hand, after it regrew in "Breezy," was actually a remnant of the "Grass Sword," and that Finn's right arm is actually a vine-like appendage hidden underneath his skin.
 * When Finn remembers his past lives, a sound of an opening metal door is heard which is Finn's "vault."
 * The King of Ooo is still princess of the Candy Kingdom at the end of the episode as PB is still at her Uncle Gumbald's cabin with Peppermint Butler. It is unknown if this change will remain permanent.
 * Finn sings his song with Auto-tuning. The last time he did this was in "Davey."
 * It is suggested that Finn may still have feelings for Flame Princess, as when the Catalyst Comet was giving Finn the speech about giving up everything and a opportunity to start over a new reality, the comet categorized Flame Princess as his "love."
 * Finn's arm appears to have gone back to normal at the end of the episode. When he waves to Princess Bubblegum, his arm is no longer made of vegetation.
 * The panic of the candy people doesn't seem to make them explode like in "Slumber Party Panic." It could be that Princess Bubblegum somehow fixed this problem for the candy people. It may also be that them exploding is just very rare, but still possible, as it has only happened a few times before this episode.
 * Orgalorg's fully unfurled form, in both anatomy and locomotion, bears a considerable resemblance to a vampire squid (Vampyroteuthis infernalis).

Episode connections

 * Martin first found the Space Moth in "On the Lam" and was last seen travelling in space riding in it.
 * Jake's croak dream from "The New Frontier" was successfully fulfilled, and was revealed to be not foreshadowing his death like Finn and Jake assumed, but foreshadowing Banana Man saving his life.
 * Finn's identity as a comet and a butterfly was previously revealed in "The Vault" as a past life.
 * The thorn in Finn's hand seen in "Breezy" and "Is That You?" appears again, revealing itself to be the grass sword first shown in the episode "Blade of Grass."
 * The ship Orgalorg modified is the same one used by Princess Bubblegum in "The Tower."
 * The Purple Comet uses Betty as the image for madness since she gained wizard powers and went crazy in "You Forgot Your Floaties."
 * Finn's premonition dream from "Hoots" is fulfilled this episode. Some elements of the dream can be seen:
 * The environment where they are is purple, similar to the how the Land of Ooo's sky and environment gained a purple hue because of the comet's presence.
 * Jake said "say goodbye" in reverse. Finn had to say goodbye to Martin after he took the comet's offer.
 * Martin abandons Finn to a place where Finn can't reach him.
 * The Bird Woman opened a door, goes up in a ladder and takes a disco ball. In this episode, Orgalorg created the opportunity to use a spaceship to take the comet.
 * Sweet P appears in the dream due to the Lich's connection to the comet, and the fact that Finn's past life was also a cosmic entity, even though the Lich himself wasn't actually present in this episode.
 * The bear with the clock as a right arm represents the return of the grass sword as Finn's arm.
 * The only character that was not in the dream but was in the real events is the Cosmic Moth.

Production notes

 * This episode, along with "Hot Diggity Doom," is the season 6 finale.
 * This two-part episode is the first season finale since Season 1 to not end with a cliffhanger.
 * This episode had an official ghost preview weeks before it's release date to promote Cartoon Network's "It's Adventure Time at the ." The preview contained no information of the episodes it was going to be featured in.

Storyline analysis

 * This episode revealed that Finn is not entirely human, but a cosmic entity, who over time, became a human being, making him one of the oldest things in the universe, and explaining his incredible durability and toughness. It is unclear though if Finn's Blue Comet self is the same comet that appeared in Evergreen, and if all the other subsequent Catalyst Comets were creations of Finn, or if they are alter-egos of Finn, or independent entities from Finn and are just members of the same comet race.
 * The Purple Comet reveals that it has been around since forever, and in doing this experienced all kinds of things, among them embodied all that is good and evil, including The Lich, however as we know The Lich is currently inside Sweet P as shown in Gold Stars, meaning that the comet can exist at two places at the same time, or at least that it doesn't needs to come to the end of a life in order to start again as a comet. We also know that despite its knowledge and experience, the Purple Comet doesn't know about its own origins, and asks Finn if he may be its creator, to which Finn responds "Maybe, I don't know, probably not," showing that the knowledge which Orgalorg desired is not omniscient.
 * The Catalyst Comets, bring the opportunity to start over a new reality, but this doesn't means that the change is good or bad, it is just an option, however in the past the change that these comets bring has presented itself as an undesired and forced event analog to damnation.

Errors

 * Even though space is a vacuum, Finn and Jake managed to communicate with Orgalorg and Finn to Martin. This may have something to do with the Space Moth and Orgalorg being cosmic beings, however.
