An early teenage girl (Chloe Walker) was playing a war game in her x- box. She stopped playing to get in his parents' bedroom where his father fell asleep with his weed joint still burning. Shortly after they both noticed the bed is soaked of mother's blood. Coming up at the crime scene, detectives point out the father as prime suspect: anyway he's sick (suffering from MS) and his disease unable him to hold a gun; besides, the shooting came from a long range. Forensic lead detectives to a shanty building placed across the street and frequented by hookers, dealers and junkies: the bullet accidentally winded up in the apartment. So Brooks and Devlin have to look inside the crack house, where young brats are used for carrying drugs and some are compelled to do that due to addicted relatives.
Devlin is so angry in this episode towards dealers and unsympathetic mothers. He grew up in a poor family as wheel, but he stated in the past there were always been a grandma or an aunt who led you to the right pattern; at the end something terrible happened to him.
