Sweet P. deals with possible Lich related nightmares, while Fern begins to crack under his own insecurity.
Tropes:
- Alternate Universe Reed Richards Is Awesome: Heavily implied. The Lich has mentioned how Finn has bested him in many worlds. Recall how the Lich's hand was scattered across the Multiverse in "Crossover." This seems to mean that the Finn of each universe defeated their invasive and/or home Lich. Definitely adds a lot of weight to the meaning of the Lich as Finn's archnemesis.
- Be Yourself: Finn's advice to Fern, who's having trouble with, well... everything. It doesn't work and Fern decides he doesn't want to be himself, he wants to be Finn!
- Beware the Nice Ones: Who would have thought that the Lich would be destroyed once and for all by sweet little Sweet P? Granted, he's technically the Lich's former body, and he is physically strong, but still...
- Big Damn Heroes: Finn is rescued from the Lich by none other than Sweet P.
- Bittersweet Ending: The Lich is defeated again seemingly for good and Sweet P doesn't become evil, but Fern decides that he needs to become the only Finn after one too many failures.
- Call-Back:
- Clone Angst: Fern is taking all of his failures very hard, so he concludes in the end of the episode that the only way to be a success is stop being himself and be Finn; so he decides to get rid of Finn and become the only Finn.
- Despair Event Horizon: Fern hits this when he fails to stop the hand.
- The Dog Bites Back: Sweet P. is able to break from the Lich's control and slay him.
- Failure Hero: Fern, and he's not taking it well.
- Flat Character: Finn accuses the Lich of being this; the Lich counters that this means he knows exactly who he is.
- Green-Eyed Monster: Fern is very envious of Finn, and is willing to take the next logical step.
- I Have Many Names: The Lich gives two: The Ceaseless Wheel, and the Last Scholar of GOLB.
- I Just Want to Be You: The episode ends with Fern deciding that he wants to replace Finn.
- Is This Thing Still On?: Finn is leaving a message on Jake's voicemail when he attacks the Lich. Apparently he left the phone on and it recorded the entire battle, as a confused Jake is listening to it near the end.
- Lampshade Hanging: As Finn chases the Lich hand he yells at it to get ready to die... for like the fifth time!
- Not Now, Kiddo: Everyone thinks Sweet P is just having nightmares when he says someone is whispering bad things while he's sleeping. Turns out it's the Lich's hand.
- "Not So Different" Remark: Played with. Sweet P acknowledges that he has destructive potential slumbering within him...but he doesn't have to use it the way the Lich does.
- Sequel Hook: Fern ends the episode stewing over his failures at everything and decides he needs to kill Finn and replace him.
- Shut Up, Hannibal!: Finn cuts off the Lich's Evil Gloating with Blah, Blah, Blah.
- Wham Line:
- The Lich reveals that he is the "last scholar of GOLB." This not only confirms that GOLB is a malicious entity if not downright The Anti-God, but it points out that there is an even greater villain beyond the Lich and grants a a minor bit of information on who the final threat of the show will be.
- Courtesy of Fern: "It doesn't matter how hard I try, I'll always just be in the shadow of the real Finn. Unless I could become... the only Finn."
- Wham Shot: Sweet P. stabbing the Lich's hand.
- Would Hurt a Child: Fern suggests severing Sweet P's tendons to stop him from running.
