The theme for Season Three is family. The PHD has now come together as a unified division, and their stories center on how they function as a family that must cope with a budget crisis. Episodes this season explore issues of family, beginning with a tale of bigamy, and ending with two stories of family pitted against one another. The season also explores the elements of family life in America, the secrets a family keeps and the horrors a family must face. In Brenda's personal life, we meet her father for the first time along with Fritz, with some interesting results. Brenda faces a personal health crisis even as her relationship with Fritz takes a large step forward.
