Trivia

 * This episode confirms that Billy was killed by The Lich's possession in "The Lich."
 * It is confirmed that Finn's real father is alive. He is located in The Citadel, according to Billy.
 * However, it is unknown where Finn's mother lives, or if she is still living.
 * Finn finally conquered his fear over the ocean.
 * Billy was able to communicate with Finn by appearing as a constellation.
 * When Canyon left, she exited through the river meaning she is most likely a water elemental.
 * In an unused storyboard for "The Lich," Billy tells Finn about Finn's father. He was trapped in The Crystal Citadel where he lives and fights off inmates that reside there. The Citadel is also where the Billy constellation tells Finn his father is located in this episode. []
 * Finn slays the fear feaster in this episode.
 * When he does so, the Grass Sword seemed to be controlling his arm, as he slapped himself in the face before doing so, and asks the sword "Was that you, or me?"

Cultural references

 * On Billy's list, it says "Make some Kombucha."  is a lightly effervescent fermented drink of sweetened black tea that is used as a functional food which originated in Northeast China and later spread to Russia and the rest of the world.

Episode connections

 * On Billy's list, one of the things listed is "Fix an Old Car." Finn did this in "We Fixed A Truck."
 * Another item on his list is to learn to play the flute. Finn was first shown to play a flute in "Prisoners of Love."
 * A bullet on Billy's bucket list states that Billy made a website. This may be referring to the fact that there is a website in The Lich (episode) that displays the Cosmic Owl on the screen, although this could be false, since it was in Finn's dream.
 * Finn's fear of the ocean is seen again as in the episode "Ocean of Fear."

Errors

 * When Canyon removes her arms from Finn's shoulders, the Grass Sword isn't seen on Finn's wrist.

Production notes

 * This episode is the 5th season's finale.
