Last but certainly not least, during the last few minutes of the finale, Preach (Kareem J. Grimes) is greeted behind bars by an old friend he calls "Mo" (Erica Peeples). Fans learn that "Mo" is Tyrone's (Demetrius Shipp Jr.) older sister when she says, "Did you really think that I would let someone murder my baby brother and I wouldn't come back to town?" Although she doesn't explicitly say she wants revenge, she says, "Ruth Scott may have pulled the trigger, but she didn't take him down alone." Previously, we saw Coop (Bre-Z) try to take down Tyrone time and time again. Not to mention, at the very end of the episode, as Coop is heading off for tour, fans see Mo sitting in a car with her sights dead set on Coop, as she says goodbye to the James family.
