Three episodes in, and the Chatsworth estate continues to have a livelier feel than in recent series. Tonight, while the rest of the estate thinks Kelly (Sally Carman) is coping well with the loss of her baby, only Marty (Jack Deam) sees how her refusal to grieve is making her unstable. Elsewhere, Billy (Michael Taylor) reluctantly accepts Mimi's (Tina Malone) insistence on an open marriage.
