It's all so awesome that I had a hard time picking only a few things to comment on. I love the way that Ron and Hermione (and Harry) interact - we don't often see them just fooling around in canon; it was nice :). As was the includion of Neville, of course.

Luna...interesting to see where you'll go with their relationship. I know I'm not the only one that has a new OT3...

Good incorporation of HBP info into the fic without making it boring for people who've already read the scenes. Hepzibah really is terribly tragic in her innocent infatuation.

And does evil!locket mean that RAB didn't succeed in this timeline?

Cliffies are good, because they lead to resolution in the next installment! Looking forward to what comes next :D...
