Seems like I always need help finding something, haha.

Does anyone remember a fic that was about, I *think*, the daughter of Dr. Quack? It was ten years after Nack the Weasel disappeared, Sonic was dead, and Nack suddenly turns up at the hospital, having gone through a time warp or something. He had killed Dr. Quack in the past, something that deeply affected the daughter. They got talking and he told her he wouldn't change having killed Dr. Quack, because it was a big part of what made the daughter who she is today. And ... I don't remember some of the other details, but he ends up going back to the past and making it so Sonic doesn't die. Then in the present, he has sacrificed his life. Don't remember how, but it had something to do with getting Sonic back. And I think Sonic and Sally were at his grave.

I remember the story so well, probably because it's one of the only things I've read that shows a better side to Nack the Weasel. Yet of course I don't remember the author or the name. Anyone?
