Preacher Vernon is a black church preacher whom Denzel has known since he was little. Years later, Vernon suffers from snake venom-related brain damage due to being bitten many times by rattlesnakes as well as sticking them inside his pants. His left eye now has a cataract and a scar on the left side of his face. Denzel hired Vernon to exorcise Donnie Cunaman. He holds a Bible with all blank pages.
