To be fair, Scud didn't know why he'd come either. Okay, no. That was a lie. He'd heard there was going to be a party, liked the idea of booze, and didn't have enough inhibitions to not show up to a party, even if he didn't know the people.
He'd just done a pretty great kegs stand with a bunch of people he didn't know, and now he was sneaking off to the side to light up a smoke and grab a drink that didn't require physical exertion. "Oh, hey," he said to the other man, because Scud kind of just spoke to anyone.
