you were an au traveler, and you know error pretty well, you always go to him when yyou're bored or want to talk

today was Halloween. And you had decided to go to the anti-void to tease him about it, since he always said he hated all holidays

once you got there, you saw him in his beanbag chair, and he was wearing...a Halloween devil costume?? You got closer to him, and once he noticed he let out a glitched yelp, before quickly turning away to cover himself

"AH-! w-why are you here-??"
