When exactly was it he'd learned to play card games? No, not the type his parents played, but the kind where gambling was involved? He reckoned that James and Sirius had taught him somewhere along the way... likely passing the time on one of the many dark, cold Scottish nights they'd spent together in Gryffindor Tower. Of course, like every other potentially shady skill he'd acquired, it was learned partially out of the desire to join in the fun, but also in part, self defense. In times past, he'd played their games because he knew that if he didn't, then they'd tease him mercilessly until he did. But that was the past... now he played simply because he enjoyed the fact that he could bluff, and his two closest friends hadn't figured him out yet.
He sat quietly, staring at his cards, waiting, until the silence was broken by Sirius. "Even Voldemort what?" he asked, nearly speaking over Sirius as he asked about the beer. "Beer, yes please." he nodded, not looking up from his cards. "What were you thinking about?" he asked, laying his hand on the table, face down. "And perhaps some cheese and crackers, too." he said, standing, knowing Sirius wasn't likely to do even the smallest thing in the kitchen, and knowing if he wanted food he had to get it himself... and likely for the rest of them as well. "No peeking." he warned, pointing at James, giving him a half-teasing, half-serious look. "I'll not have your cheating ways robbing me of my jackpot." he chuckled.
