Greg has entered the room and looked about, slightly impressed but deciding not showing it. He was in a sour mood still. The train ride had been boring as hell and to his dismay, many of his fellow slyths were not on it, opting to stay at home until absolutely necessary to return. Greg understood now why his brothers had been so eager to get him on the train; they'd had their fun and were tossing the dead weight (which Greg was certain was himself.) Greg had made his way up to the castle, and then down into a fairly deserted Slytherin common room. Unfucking believable! he'd thought to himself at the time. It was almost as unbearable as the visit to Theo's.
He had heard the announcement at dinner and decided that if he couldn't sneak out to Hogsmeade, at the very least he was going to go and hang out in the Great Hall.
Thus, he found a seat and sat, watching the mixing crowd and feeling completely out of sorts.
