I'm looking for a story and I'd not quite sure how to tag it but I'll do my best.

It a story where Sam died, it might have been when he jumped into the cage. Dean goes to Lisa and they eventually have a baby boy and name him Sam. When Sam is young, he starts talking about hunting and such things, "Daddy, do you remember when we fought that werewolf?" stuff like that. Dean realizes, in a way, this is his Sam. As "new" Sam starts getting older, he kind of forgets it all and winds up going to Stanford and becoming a lawyer.

Please and thanks.
