Office Halloween party. Everyone is invited, even people that may technically be dead in canon. (Ben, Elena. And of course Matt, Foggy, Karen, Claire, Brett, Marcey, etc.)
Costumes are mandatory. What does everyone dress up as?
Does someone spike the punch and subsequent drunk card games? Is there blind pumpkin carving? Who dresses up as Daredevil as a joke?

Literally, all the adorable Halloweenness.
