Hi, my first post here. :)

I remember reading a fic which was a different ending of "Nightmare", where Max Miller didn't kill himself. He ended up travelling with Sam and Dean and he helped Sam to control his abilities. I also remember that Dean didn't like Max and he was very jealous of him.
I think it was Wincest, but that could just be me making things up again, lol.

Thanks! :D
