Biography[]
Season 1[]
Diamond is first seen in Prison cutting someone's hair. Rojas tells the rest of his crew to let Diamond first get comfortable on the outside, then make the call. Jenard picks him up and Diamond tells his brother that he isn't the same person he was before prison.
Diamond finds out about Tommy saving Jenard and Vic in a warehouse and he sees Tommy in his barbershop the next day. Tommy and Diamond are both kidnapped by two members of Rojas' crew and forced to get them money within three hours. Having just got out of prison, Diamond is cautious of the city being heated with cops. An officer pulls out a gun on him and almost shoots, but Tommy arrives and the tension fades.
Diamond goes with Tommy to a meeting with Vic, Walter and Paulie regarding Tommy's plans for the Chicago drug game. Walter refuses to work with Diamond because of their history, blaming him for an attack on Paulie's wife. Diamond claims that wasn't him and walks out. After Tommy kills Tatiana and Vic kills 2 Serbians, Vic, Tommy and Diamond all agree that they should take out the Serbians to gain a bigger pipeline in Chicago. They bring Jenard, Simon McDougal and Elijah in on it as well. The attack on the Serbians is well executed and Diamond shoots one of them.
Seamus Bennigan approaches Diamond whilst he's jogging and tells him to get in a vehicle. Diamond says that him and Bennigan don't have any history. Bennigan asks if he knows the name Keke Watkins and says that her life will never be the same because of him. Diamond tells him that he has made amends and threatens Bennigan about Vic paying him in exchange for information. Diamond meets a woman named Adrienne at his local diner and immediately bonds with her. The two engage in sexual activity but Adrienne seems to have some kind of agenda. Officer Bennigan later robs the safe in Diamond's barbershop as he is in need of 100K after being blackmailed by Lieutenant Warshawski, and Diamond obliges because he feels bad about what happened to Bennigan's sister and because he is held at gunpoint.
Diamond finds out that Jenard and Blaxton are plotting to kill him because Jenard wants to run CBI. Jenard runs into the barbershop and tries to kill him but he and Adrienne manage to get away. Diamond later kills Blaxton because of this and his body is found by Jenard. He doesn't know what to do about Jenard. He and Jenard have a brief fight but he decides not to kill him, instead they agree that they'll go their separate ways with some CBI soldiers teaming with Diamond and some possibly teaming with Jenard.
