Okay, I've scoured tags for this, but I just can't find it.

In this fic I think Sam dies at Cold Oak - same as in the series - but instead of Dean selling his soul to bring Sam back, the demon sends him back to when he was a child and tells him that as long as Sam doesn't love him, he won't die. Basically, Dean was a total ass to Sam his whole life, but was really the same Dean he'd always been underneath.

Anyone remember this?

Thanks in advance for any help!
