Strange is quickly learning that he needs to A: be obnoxiously specific with the requests he makes and B: buy a goddamn ashtray because he's got a feeling Childermass'll try to smoke in here again just to be obnoxious for the sake of being obnoxious. Still, he's on a little bit of a power high because the order actually worked. Sure, there was now a little scorch mark on the floor that'll probably come out of his deposit, but Strange is just now realizing that Childermass actually listened to that order. So naturally, he's going to do give another one.

"The trashcan is underneath the sink in the kitchen. If there's any of that cigarette left, pick it up and throw it away there." But if Childermass had already managed to grind the cigarette into the wood...well, that just means that Strange would have to pick up cleaning supplies from the store later.

"I honestly don't see why you're being so difficult, changeling. This would be easier for you if you just behaved."
