"Oh," Billy said, really not sure where else to go with the conversation now. Obviously Remy was doing something, and it probably as just as simple as playing with a deck of cards. He he'd managed to find a deck that had all the cards in it - especially ones that looked so artistic - at the school, was beyond Billy's ability to reason. He knew that several of the puzzles that the school had were missing at least three pieces. Which was the main reason why Billy had stopped doing puzzles in the first place.
Speaking of busy hands, Billy picked up the half a sandwich he was chewing on earlier and continued to do so. No sense in letting it go to waste. He figured if Remy wanted to be left alone, the other guy was comfortable enough to tell Billy to leave.
