Sam and Dean are messed up and wonderful in sonofabiscuit77's
All in the Game (http://sonofabiscuit77.livejournal.com/23985.html)

Summary: SPN AU, Dad was shot and killed by a police officer when Sam was five... Sam and Dean grow up in care on Baltimore’s Westside where drug-dealers and drug-pushers rule the streets, where kids face the reality of playing the Game or becoming a junkie, where two white boys have nothing to rely on except each other and their own smarts.
