I loved this story so much, and for so many, many reasons, that I could not (and still cannot) form a response that adequately explains what it does to me. I apologize for having to ride on cluegirl's coat-tails, but she captured perfectly what I wanted to say about the use of Ron in this story. It's such a fresh perspective, one I don't read often (at least not done like this), and I adore it. This is the Ron I know, the one in my head, the one I saw in the books. I'm not sure why people like to bash him so. He's complex, just like the rest of us, and it took a rash, angry decision to help him see the error of his ways. I think he more than made up for it. I can't say I wouldn't have done the same thing in his shoes, especially if I, too, was under the influence of a Horcrux.
So thank you. Thank you for redeeming Ron for me (and hopefully for many others!) and for writing a singularly beautiful and triumphant story.
