Snow!

Snow! It came on suddenly, didn't it? But maybe that's normal here. It had been snowy when Feuilly first arrived; he remembers barreling around outside in it, in his June clothing, hugging himself with his hands tucked up under his arms to keep warm, too excited by the strangeness to go inside--

That same excitement simmers in him all morning while he goes about his self-imposed schedule of work, and only after he has finished his Latin lesson does he hurry over to Harry's room. No Harry there, but the dogs are in: Feuilly gets their leashes on and bundles along outdoors. It seems very likely that Harry's already there.
