Mess With Sam, Sign Up For a Painful Death

Dean is tired of waiting. He's going after the bastards that when after Sam if it's the last thing he does. Unfortunately, though he has had to make a few deals with an old enemy. Dealing with revenge, taking care of a traumatized little brother and a kinda pissed off prophet and his mother is harder than it seems. AU after Southern Comfort with some canon parts. Warning inside.
