I'd imagine he has a fun time dressing up for Halloween if given the opportunity. Guessing in a modern AU, yeah he'd definitely go to a Halloween party.. and he dresses as a vampire (self indulgent fantasy for myself hehe).
Also nah he's not doing shit for the kids unless its something he has to do for work.
He's definitelyyyy spiking candy with drugs and giving them to (You) because he's expecting you to be the naive fool that'd take candy and drinks from him without questioning it.
