I agree with senjy. And I'll add that I liked this insight into such an IC Snape's mind. Also, I don't know if you meant it or not, but I read it as a trick of Harry's. I don't know why but this is the second fic this week (and it's only Monday) that I've read that I imagined Harry to be up to something. For example with this fic: I imagined that Harry may have forged the note from his mum and all the rest and slyly suggested the marriage. It was his intent all along. And he figured playing calm was the best way to get to Snape. See what I mean? Anyway, great little fic you have here!
