Spike had been down in the greenhouses, as evidenced by the smears of dirt on his face and over his hands, and a confused look flickered across his face as he saw all the 'Claws outside the Common Room. That look soon turned to worry, since if they couldn't get the knocker's riddle, he didn't stand a chance of helping either. Spike and the knocker had had a stormy relationship since day one. He was sure the thing hadn't accepted how he'd made it into Ravenclaw, and gave him a particularly hard time about it.

"Whatchu all doing out here?" Spike asked generally to the crowd. "The knocker being mean with its riddle again?" ...or had something else happened?
