Sam knew it wasn't healthy, but he was battling against a predisposition to alcoholism that was the result of generations. It was hardly his fault that drinking had always been a patented Winchester coping mechanism, when the shit hit the fan they hit the bottle and they hit it hard. He wasn't quite at the stage his father had been at, or even his brother for that matter. John had basically been an alcoholic from the day Mary had died, and Dean drank most days though only to excess if something had happened or was playing on his mind. Sam rarely drank day to day, but when he was going through something trying he tended to binge. Unsurprisingly the incidences of drinking had increased significantly since his arrival in Marrowood.
Death by zombie definitely counted as 'something trying', but even he could recognise he'd overdone it lately and he needed to put a stop to it.
As far as jokes went he supposed there were worse things his friends could tease him about, so he was more than willing to take it in good humour. Mostly. "That's still so funny." He said flatly. Sam nodded, he hadn't spent as long as Derek had acting as a guardian and he hadn't had as many kids to deal with, it was pretty much just Claire and Thalia and then Claire's sort of boyfriend Jeremy. That had been enough hormones to last him a lifetime though. "I get that. You're welcome to hide out here, but I can't exactly offer you a drink or anything." Sam smirked slightly and somehow managed to look sort of sheepish at the same time. (Reply to this)(Parent)
