Richard T. Jones is listed as "credit only" for this episode but Sgt. Gray is in the first scene in the police station as he speaks to James about James' and Harper's daughter. With spoken lines, Jones should be credited as appearing in the episode.
Guest star Bridget Regan and series regular Shawn Ashmore, who play ex-lovers here, previously starred in Devil's Gate (2017) together with him playing a FBI agent tracking a missing woman (Regan).
