Arthur has a knack for remembering faces, but that doesn't mean he knows every single face of every single being (supernatural or not) that calls Hillingdon its home. They don't exactly keep a membership list, so it's not uncommon for Arthur to seem someone in the House's halls that he's never seen before.

Some people, though. Some people catch his eye and he can tell they're out of place. Ghoul is one of these people. Arthur spots him wandering down a hallway that he's about to bypass, and he's in a cranky enough mood that he decides he's going to insert himself into whatever fishy situation this is.

"Hey," he says, like a teacher who's found a student out of class and is just So Fucking Done. "Who are you."
