** Played straight with Dipper and Mabel. In ''Gravity Falls'', the Pines Twins were just staying with Stan for the summer. Here, their parents died in some kind of accident, and Stan was the only relative available to take them in.

* DeathByAdaptation: Dipper and Mabel's parents were killed in an accident, resulting in Stan adopting them. It's also implied that Ford is dead since Stan says he's "no longer with us."

** Jazz is confirmed to be a lesbian, in this verse.

* {{Cliffhanger}}: Chapter 10 ends right in the middle of the fight with the Lunch Lady, with Rhody bringing her cleaver down right as it ends.

* CrossoverCouple: Dash Baxter and Courtney Babcock.

* {{BFS}}: In this story, Wendy has a double-edged sword for a weapon that Danny describes as being almost ridiculously large.
* BigSisterInstinct: Jazz noticed that Danny was talking to Ember by the school gates and asks him who she is, out of concern for him.

* MythologyGag: When talking about living in a macabre town like Blithe Hollow, Tucker says "some people turn goth, I research murders." Possibly a nod to their goth friend Sam Manson from the series, who has yet to appear this story.

* Catchphrase: The Box Ghost repeatedly whispers, "''Beware...''" in a CreepyMonotone.

* Valkyries: Brunhilde the Valkyrie is one of the Reapers.

* JacobMarleyApparel: Anyone who shows up in the afterlife waiting room displays signs of what killed them. Danny looks as beaten up as you'd expect someone who got rammed by a bus to look, the receptionist has scarred wrists, presumably from suicide, and the man who briefly fights Danny for a ticket has a bullet hole in his head.

* ShipperOnDeck: Ember, Tucker and [[NotSoAboveItAll Alistair]] all think that Wendy Corduroy would make a good girlfriend for Danny.

* BadassGay: Ember [=McLain=]. She's a lesbian banshee and agent of the Fates armed with a magic guitar who fights [[GhastlyGhost ghostly monsters]] as well as the rest of the crew.

* BadassGay: Ember McLain. She's a lesbian banshee and agent of the Fates armed with a magic guitar who fights [[GhastlyGhost ghostly monsters]] as well as the rest of the crew.

* InnocentlyInsensitive: Dash innocently makes Courtney uncomfortable by calling Norman weird in chapter 6, and again when he tries to defend Mitch and Scott from a group of homophobic jerks. He says that Courtney is twice as hot as their girlfriends.

* IAlwaysWantedToSayThat: Danny says this right before performing a 'kick open the doors'-style DramaticEntrance.

** CurseEscapeClause: In this story, the Witch can only be resurrected if it's both Halloween and the town is filled with fear.

* Additionally, Danny appears to be growing a crush on Wendy Corduroy.

* SealedInsideAPersonShapedCan: Since banishing the Lunch Lady didn't work, Dipper looks in one of Ford's old journals and finds a spell that allows a ghost to be sealed inside a person, but leaves them at risk of DemonicPossession. But since Danny can undergo SymbioticPossession with Alistair without being taken over, Dipper brings up the possibility of sealing the ghosts inside of ''him''. It works with no apparent side effects for the Lunch Lady and Box Ghost.

* PoliceBrutality: Apparently, when the Boxcar Butcher, Wayne Jeffries, showed up at Blithe Hollow, the police shot him because he was too dangerous to be left alive.

** When being chased by one of the Lucnhlady Ghost's minions, Dipper tries to use a banishment spell that sounds like the one from ''Film/ArmyOfDarkness''. He even flubs the last word, but with a thankfully more beneficial outcome.

* Disabled in the Adaptation: In Gravity Falls canon, Manly Dan Corduroy has all four limbs intact. Here, he has an artificial leg, presumably from losing his real one at some point in his career in the Society of the Blind Eye.
