Plot
Locos show up at Brother Sam's garage
Julio headed to Brother Sam's garage to try to intimidate Brother Sam with a gun into getting Nick back into the Locos. But Brother Sam just looked him in the eye telling him to either kill him or get out. Julio was about to pull the trigger when Dexter, who was with Sam at the time, revealed he worked with Miami Metro and advised them to walk out. They took that advice, but not before Julio gloated about killing Nunez to Dexter which prompted Dexter to target and kill him.
The Locos blamed Brother Sam for his disappearance and eventually Leo was selected to replace Julio as leader. Nick later came back to the gang wishing to get back in but Leo wouldn't accept him unless he killed Sam and brought proof he did. Nick then went to Brother Sam's garage and shot him three times and stole the security disk to show Leo. Leo had a party celebrating the event, but after Miami Metro showed up at his house where Leo was shot and killed in a shootout where they believe he killed Sam. Dexter eventually found out Nick killed Sam and tried to forgive him, but ended up killing him instead.
