Thank you! And yes, exactly, if anyone can survive the circumstances, it'll be the Slytherins, as you say. I really appreciate your comment about the Slytherin view of canon, because I know it's uncomfortable, but I was trying to put myself in their shoes and think about how it would look to them. I'm glad that worked for you.
And Greg's not as dense as canon makes out. After all, he did make it through his classes somehow. ;-)
