When Helen Rosenthal and Ellen Craig are talking in the nurses' lounge, Helen mentions that her first husband, Edgar Eisenberg, recently died. Actor Dick Shawn, who played Edgar in The Equalizer (1986) had died on April 17, 1987, approximately five months before this episode aired.
During an argument, Ellen smashes a grapefruit half into Marks face. This is a homage to a famous scene in the movie "The Public Enemy" wherein James Cagney did the same thing to Mae Clarke!
Fiscus, who always wears Boston sports gear, shows up wearing a New York jacket. Real life Boston fans wouldn't be caught dead in NY gear.
Ronny Cox joins the cast as John Gideon for the final season.
First time Sagan Lewis, France Nuyen, and Jennifer Savidge are included in the opening credits.
