 This episode is Sherry Stringfield (qv)s final appearance. She  left before writers could write a storyline for her character to  leave the series. Stringfield was the last original cast member to  still be on the show at this point (although she left between 1996  and 2001). As of her departure, all main cast members from the first  two seasons are gone (though Laura Innes (I) (qv), who joined in  season 3, was a recurring guest star in season 2).
