Gosh, Roo. Even though it seems like Harry'll be all right in the end, this one makes me sad. I like the way you've portrayed Dudley here, but I'm especially in love with your characterization of Hermione- the line about her "thinking line" is excellent, and the way you've described her as a self-confident healer who knows what she's doing and how to handle patients is wonderful. And the line about them not even having the conversation if Harry wasn't her best friend... *sigh* You've just done an excellent job with her, here.
And gosh, I can't even bear to talk about Harry and Severus. Just...it's so sad. I get that it's meant to end on a hopeful note, but especially with what you said about Severus constantly researching and trying to find things out... It just makes it that much sadder. *sigh* Excellent job, dear. Broke my heart.
