History Recap / GravityFallsS2E15TheLastMabelcorn

** It nearly happens to Dipper when he finds out Ford was involved with Bill.

* TemptingFate: Before Ford calls the family meeting, Dipper and Mabel are about to play a ''{{Jumanji}}'' {{Expy}} literally named "What Could Go Wrong?".

* HeroicSacrifice: Wendy unwittingly does this with her determination to get the unicorn hair to protect the Shack; when Bill flashes through potential Gravity Falls citizens to possess, her image appears, meaning she could be his next victim.

* TakeThat:
** Celestabellebethabelle is an obvious parody of [[WesternAnimation/MyLittlePonyFriendshipIsMagic Princess Celestia]], a benevolent ruler of Ponyville who is a figure of wisdom and authority and possibly a TricksterMentor. As fitting the cynical Gravity Falls universe, Celestabellebethabelle pretends to be wise and able to look into humans' hearts, while just wanting to be left alone.
** The fact that Wendy is the first person to propose taking Celestabelle's hair through violence has some nice meta-irony to it, since [[WriteWhoYouKnow the girl who she was based on]] supposedly grew up to be Creator/LaurenFaust.

* GRatedDrug: The gnome wants butterflies as payment.

** The symbol of Bill that Ford found in the cave is identical to the tapestry image in the Northwest Manor.
** Dipper's trauma from Bill possessing him comes back in full force when he thinks Ford has been possessed, causing him to fire the memory gun at his great-uncle.

** [=McGucket=] warning "fear the beast with just one eye..." revealed to Ford that Bill couldn't be trusted.

** Stan's still trying to get rid of the pugs mentioned in the last episode.
** Mabel and Dipper recount how they beat Bill with "kittens and tickles" to Ford when he asks if they recognize Bill's symbol.
** Dipper's mind sings "Disco Girl".

** Dipper still misses Tyrone as seen on the screen.

* DidYouJustPunchOutCthulhu:
** The memory gun can do this to Bill if he possesses someone, according to Ford. It will "erase" him from a victim's mind.

** Mabel delivers a strong hook to Celestabellebethabelle's nose, making the unicorn bleed. At first everyone is shocked, but then the confrontation leads to Mabel and the girls fighting the unicorns for their hair and winning.

* ExactOverhearing: It turns out Ford heard Stan call him "a dangerous know-it-all" and it was on his mind when Dipper read Ford's thoughts. While Ford and Stan aren't on speaking terms, it shows that Ford did care what his brother said.

* ArbitrarySkepticism: Despite having encounters with the supernatural in previous episodes, Wendy insists that unicorns aren't real.

* HiddenDepths: Grunkle Stan can speak fluent Spanish.

* JerkassHasAPoint: While she turned out to be a huge dick and didn't mean a word of her "pure of heart" shtick, Celestabellebethabelle wasn't wrong about one thing: doing good deeds to make yourself look good isn't all that noble.
** In addition, Mabel was making the good deeds about self-validation instead of a way to get hair to protect the Mystery Shack. Only when she [[ViolenceReallyIsTheAnswer beats the crap out of the unicorns for their hair]], picking the bigger-picture good over looking good, does Ford tell her that she really is a good person.

** Dipper still misses Tyron as seen on the screen.

--> That said, he ultimately compliments Dipper on his paranoia, wishing he'd been as cautious when he first met Bill. This could indicate that he still hasn't learned his lesson.

As fitting the cynical Gravity Falls universe, Celestabellebethabelle pretends to be wise and able to look into humans' hearts, while just wanting to be left alone.

* BigSisterInstinct: Wendy is shown to be very protective of Mable in this episode.

* [[BigBrotherInstinct Big Sister Instinct]]: Wendy is shown to be very protective of Mable in this episode.

* LastOfHerKind: Celestabellebethabelle introduces herself as this.

* CharacterDevelopment: Mabel comes to terms with the fact that just because she has flaws, doesn't mean that she's a bad person.

** The title of the episode is an homage to ''Literature/TheLastUnicorn''.

* YouAreTooLate: Invoked by Bill when Ford confronts him; the portal has been built, and one way or another it will soon open. Ford tries to destroy his instructions of how to run the portal, so that no one else can open it, but Bill's words come true when the fight between Stan and Ford leads to Ford going through the portal, and Stan creating a rift by saving his brother. Ford's Plan B is to make sure Bill never gets his hands on the rift.

* OhCrap: Ford gets this during his nightmare with Bill.

* FreezeFrameBonus: Mabel's list of good deeds.

* GettingCrapPastTheRadar: Grenda conducts a drug deal ([[GRatedDrug for fairy dust]]), drugs a unicorn, and chloroforms a satyr who tries to sound the alarm.
