Before the One You Serve (слэш)

When Dean comes to get Sam at Stanford, he finds him living with Brady. And Dean doesn't trust Brady, even though he can't quite put his finger on why. Not at first.
written for the 2014 Antichristmas Gift exchange for delanach for the prompt:
AU from the beginning of the Pilot. Dean finds Sam with Brady, not Jess, when he goes to get him from Stanford. Brady has been drawing out Sam’s darker side and preparing him for his role as the Boy King of Hell, but Sam belonged to Dean first, and Dean wants him back, even if that means accepting his darker side.
