He's clearly at a costume party so why did the devil scare him? Devils don't exist. At least not in this form. They only exists as little creatures that appear on your shoulder. Everyone knows that.
Speaking of a costume party... I don't like how "cosplay" is used here. I mean, yes, Brutus is technically cosplaying but is it a cosplay party (are those a thing?) or is it just a costume party?
