A bounty hunter who kidnapped the wrong mark during his first assignment. After Bull learns their client received an anonymous tip that led him to nab the wrong person, he decides on a "Mistake of Fact" defense, which asserts their client's actions were based on factual error.

Bull helps mount a defense for Taylor's brother-in-law, Ralph Kelly, a prison guard charged with manslaughter for the drowning deaths of two inmates in the middle of a hurricane. During the trial, Bull aims to convince the jury that his client tried to prevent a "greater harm" when he abandoned his prison command to evacuate his own family.
