Dean Adopted And Taking Off After He Finds Out

[seren-mercury.livejournal.com]

Asking for your help yet again...

A request made reminded me of a gen fic I read a while ago. Sam and Dean encountered a demon (pretty damn sure it was a demon could be something else evil) and Sam gets pretty messed up. I believe the injury was centered around his leg he had to stay in the hospital for a few weeks and needed a cane when he finally left. Anyway, Dean digs into his past because of what the demon said to him and discovers that he was adopted and he starts to unravel. He sells the Impala, he hocks most of their weapons and leaves a bag with whatever was left and some cash in the motel before splitting. Sam and John eventually discover that Dean had ripped the journal to shreds in the room he stayed in, purposefully separate from his brother. They try to find him and Sam starts dreaming about a father who turns out to be Dean's biological one. The whole family had angelic names and the father was thought to have died in a car crash where baby Dean was said to have died but another son survived.

I know I read it on ff.net, and that it wasn't finished so I'm kind of hoping that someone knows where I can find a full version if there is one.

It was a great story and I have no idea where to start. I can't remember the author or the summary.

Any help at all would be wonderful.

Thanks in advance.
