"I don't know." Q thinks for a moment, then shrugs. "To taunt him maybe?" Not likely, but he's not really sure of anything about that time anymore.
"Well, I did try to kill him once he was there. And I knew he would be, or at least I was fairly certain. Gryffindors are terribly predictable." He hunches in on himself. "He was only eleven," he mutters.
Q takes the paper and scans it avidly, squinting a bit at Severus cramped handwriting. Now it's his turn to roll his eyes. "That is so you Severus," he tells him. "You sat down and made a list of everything that might happen and you prepared yourself for any eventuality." He hands the paper back. "I know what you mean. I miss the library at Hogwarts terribly, not to mention that all of my own books are gone." He has an idea about getting ingredients for Severus, but he's not sure how to bring up the subject. "I have," Q smiles broadly. "I'm the groundskeeper for the spa here."
