B opens his mouth to say no. He really should get back to his own cabin. Stop bothering Lark. Lark's cabin is in shambles, and Alec could come back any time. And Lark is probably just as tired as he is.

Nothing comes out. He swallows, and says more honestly, in a smaller voice, "Maybe." Dogs are safe. Wolves are safe, too, even if technically they're people. He can't promise he'd actually nap, or that he wouldn't wind up bawling into Lark's fur, but it's not like it'd be the first time.
