NCIS New Orleans actress CCH Pounder made a guest appearance in an episode of Quantum Leap in 1990. The episode, titled "Black On White On Fire," saw Pounder play the character of Mama Harper, the mother of a black medical student named Ray Harper. The episode revolved around Ray's interracial relationship and the racial tensions of the 1965 race riots in Watts. Pounder's appearance in Quantum Leap showcased a different look and character compared to her role as Dr. Loretta Wade in NCIS New Orleans. Pounder has since been busy with other projects, including The Good Fight and the Avatar films.
