Childermass could just as easily cast a spell against this man. Do him harm, play a trick on him, or anything besides. But he does not. He is not in the habit of creating trouble for himself if at all possible. If given the opportunity to leave peaceably rather than have this end in some sort of a duel, Childermass understands what the smarter option of the two is.

He quirks something of an ironic smile at the other man. "You'll let me," he repeats, as though he thinks it's a funny way to put it. Maybe he does, it's hard to tell with Childermass, just about everything he does is sarcastic and sardonic. "Very well then." He tips his hat at the other man, aware that he's pushing it, even as he turns to take his leave. And literally disappearing into the shadows before him.
