The last time Wilson played poker with House, it had been at some party at random somebody's apartment. He remembered thinking that was remarkable, because House isn't sociable (understatement! he thought) and he remembered tagging along because otherwise House was going to get drunk and spew vitriol all over the damn place unless someone amused him with some suitable distraction. Poker, for instance.
The last thing he remembered about that night is that when he woke up the next morning, his head felt more than a little fuzzy, his wallet was definitely emptied and he couldn't find his pants anywhere.
