In the two-part season finale, "Citizen Trundel" (written by O'Connor, Cynthia Deming, and William J. Royce), Harriet DeLong's sister Natalie is murdered by order of her secret lover and the married father of her nine-year-old son, millionaire businessman V.J. "Vidge" Trundel. The situation causes Harriet a tremendous amount of anguish, rage, and frustration, not only because of Natalie's murder but because Chief Gillespie is reluctant to pursue the powerful Trundel as a suspect. These are the first episodes in which we see Bill and Harriet's relationship begin to blossom. During this period, he is able to see beyond her hardened exterior and finds a vulnerable and sensitive woman behind it; she discovers his compassionate side. From this point on, a camaraderie is formed between the two.
