Frank Furillo Jr. (Frank and Fay's son) makes the first of only two appearances here. Although he is frequently referred to throughout the series , the character only ever appears twice, once in this episode, and once more in the 1985 episode "Davenport in a Storm" (S05 E15). 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" also mark his only credited screen appearances as an actor.
