Hi ! I'm sorry to bother you but there's a great fic that I read some time ago and can't seem to find anywhere despite no small amount of looking.

It was a wincest fic and John found out pre-series. He wasn't thrilled, to say the least. He then kicked Dean out. I'm a bit hazy on the details but I think he threatened him with a gun to get him to leave.

John then leaves with Sam and Dean can't find them. He never gives up on his search for his brother and somehow ends up as a professor (at Stanford maybe). One day Sam comes in his office to ask something to the teacher he doesn't know is his brother. Follows an angsty reunion where Dean discovers that John drugged Sam that night and told him that Dean left on his own.

That's all I can remember I think. Thanks in advance to all those that took the time to read this post and sorry to bother you. By the way, if this fic doesn't exist and it somehow created itself in my head, may some talented author write it because it is awesome.

Thanks again.

Ciao.

P.S.: Fixed the strange font running across the page it really wasn't intentional.-_-" Thanks to the awesome mods !
