** The Box Ghost is a brutal SerialKiller, who ''also'' cannibalized his victims when he was alive. In the show, he was a HarmlessVillain who rarely hurt anyone, though mostly because he was barely a threat.

* ParadoxPerson: Since one of Danny's ancestors cheated death to save his pregnant wife, Danny's entire family line is like this. This is what allows Death to send him back with the ability to be possessed by the said ancestor to gain ghostly powers.

* 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''.

** This also allows the two of them to exchange information and learned skills with each other. For example, in preperation for their first fight in chapter 6, Alistair gives Danny his extensive knowledge of combat...in exchange for the latter's knowledge of video games.

** The Boxcar Ghost was once Wayne Jefferies, who was struggling during the Great Depression and resorted to killing and eating body parts from his victims. Since he's the second cannibal ghost they have to fight in a row, Danny lampshades this.

When she's summoned back, the group has to stop her from cooking the school janitor.
