"That's too bad," says Castor mildly. "Magic is pretty neat."

All right, that's just about enough one-sided pleasantry. His chill only extends so far. He looks up at the guy, folds his arms, looking probably comical, sitting all stern in his pile of garbage. "So who are you?" he says. "Are you just here to interrogate me, or what?"

Interrogate is a strong word, chosen because maybe it'll get a strong reaction. Castor can't read this guy, and he doesn't know how to deal with people he can't read.
