I absolutely loved this; the ending almost had me in tears. It's very understated and subtle, but I think that's why it managed to affect me. I loved they way you wrote about "the arguments they didn't have" (and there is much in this fic that you leave unsaid, just hint at, which is what makes it so interesting). I also loved how Ginny feels that she's taking on a role, which immediately falls apart when someone brings back her old role. It leaves the question "where's the real Ginny?"
