Julius shut the door behind him firmly but quietly, not interested in letting anyone in the common room or who might be down in one of the empty class rooms know just what was happening. He guessed that some of them probably suspected, that a few of them had the same sort of agreement with Slughorn but that didn't mean he wanted this to become talked about.
"I wouldn't be here if I hadn't." He said, waiting to be offered a seat or at least something to drink. Last year Slughorn had been so obsequious - offering him sweets and glasses of wine. Now that Julius was returning, was already won, it looked as if Slughorn wasn't going to bother with seduction.
