Walter's got the presence of mind to stomp at least some of the snow off himself while Caro runs past him. It doesn't take him long to follow behind because who the fuck stays out in cold like that. Murph gets a nod for a greeting but that's mostly to be expected.

He shuffles in and ignores the dogs beside taking a very brief headcount. His gruff appearance is probably immediately destroyed by the small, quiet mew from somewhere inside his jacket.
