Bosch: Legacy has a lot of plot threads that run over from the original Bosch series on Prime Video, and villains that keep turning up to haunt ex LAPD cop turned private investigator Harry Bosch and defense lawyer, Honey Chandler. One of those villains is Carl Rogers, who, despite being killed by the Russians in season 1, is still causing trouble from the grave via an FBI investigation into Bosch and Chandler in connection with his murder, led by Agent William Baron, who is played by former Brat pack star, Anthony Michael Hall in season 2.
