Biography
Other than being a member and second in command of the RSK, not much is known about Q-Dubs or his past life. However, after the death of his cousin Rolla at the hands of Ghost, Q-dubs took over as the leader of the RSK gang. He later met up with Ghost to discuss things going on with the drug business and the changes after Rolla's death, which seem to have ended pretty well. However, Q-Dubs later had a confrontation with Tommy and Kanan, which got out of hand as Q-Dubs didn't trust them or Ruiz and his gang as he found out who killed Rolla. Q-Dubs and his men were then killed by Kanan and Tommy.
