He had heard voices outside, and since he was done with his brewing for the night anyway, he decided to investigate. The sight that greeted him made him smirk: one Ravenclaw boy and one Hufflepuff girl, both out past curfew. The only question was, would they make it worth his while not to take House points. "I do believe the same could be said of you," he said, smirking, as he made his way up the corridor toward the pair of them.
