I sort of thought you might say that.

You know, someone might think that spending time with Gryffindors is rubbing off on you. I mean, Miss P C has tried to kill you twice now, and you want to keep on because you could learn stuff that could help Terry fight back. Oh, sure, you say it's about the books, but what you really mean is you're planning to risk your neck for somebody else. See? There's hope for you yet!
