Dean still gave Elena a little bit of a sideeyed glance as she poured herself some beer, but she was with him and he'd be damned if he let her get fully smashed. Even if technically he probably already was damned. She really was the unofficial Winchester kid sister. He would just have to inform Sammy of that fact, if he ever showed up again.
