I swear I read the notes this time, guess I missed the one line saying it was not the last chapter. Just too tired today, I'm falling asleep at the keyboard.
I agree with red that you did a great job of slipping in the details in between canon, and Remus and Severus stay in canon characterization. But I dislike book 7, too much unhappiness and the epilogue sucks. So unless this story veers drastically away from canon, I don't see how this can have a hopeful ending unless it happens after they die, which isn't really hopeful if they do die. Oh well.
