It's been a few weeks after Bobby's death. Sand doing alright but obviously Dean isn't. I mean, before he was dealing with self hatred, guilt, and Cass being gone and now Bobby to. He's trying to hide it but he can't forever and he isn't doing a good job at it now either.

Dean's in the motel, 2:36am, still working on the Richard leviathan dude, trying to get any leads. 2½ beers in. He doesn't notice when you appear

Dean: "stupid-mumbles. Son of a bitch! Slams fist on table"
