A black television personality and preacher. Most of his work consists of activism to raise awareness for black people who are either wrongfully convicted of crimes or are murdered by police. Ruth finds him too angry, while Adisa thinks that he's the only person capable of making sure white people hear how angry black people really are. As Ruth's trial begins to move forward, Mercy offers to help her. He and Adisa organize one march but Ruth ultimately declines his help after Kennedy points out that the media attention won't do them any good. Despite this, Mercy and his followers still assemble daily outside the courthouse during Ruth's trial. Kennedy contacts him for help when she discovers that Davis was a carrier for sickle cell anemia, a disorder that mostly affects African Americans. With this information Mercy is able to find Adele, Brit's mother, and subsequently shatter Turk's conceptions about Brit, Francis, and love itself.
