Frank Furillo Jr. (Frank and Fay's son) makes only his second (and final) appearance here. Although he is frequently referred to throughout the series , the character only ever appears twice, once in this episode, and once previously in the 1982 episode "Officer of Year" (S03 E05). On both occasions, Frank Jr. was played by Jesse Bochco, the real-life son of Barbara Bosson (Fay Furillo) and series creator Steven Bochco, and these two appearances in "Hill St Blues" mark his only credited screen appearances as an actor.
