that would be awesome cause in many sad ways if you look at deans story from s1 to s7, he has in many ways just cleaning sams messes, the only major stories he had was his countdown to hell, michael destiny and his normal life with lisa and ben and sam has had more storylines than him. So yeah maybe him and this new monster dean meets come out of purgatory and this monster has a bad influence on him.
