Yeah....Ron. To be honest, I don't think he'd always react as he did, but in this universe, where he and Harry probably haven't spent much time together since the war, with what he might see as Harry 'putting Ginny off', I think it was more intolerance than immaturity. I generally think that Ron gets a bum wrap in fanfics, because I don't think he's stupid at all. But being a redhead myself :), I think he flies off the handle sometimes, leaving his brain to catch up later....
I appreciate your comment--thanks for sticking through to the end.
