"It's my laboratory. I can smoke if I want." And since he really doesn't think Childermass is gonna be swapping cigarettes with him like they used to, he's already tapping out another one.

Once he's lit up again, Lambert tunes out of the magic debate. Instead, he sets about cutting cheese, apple, and bread again, glad to have something to do with his hands.
