The second part of season four invites viewers back to the couch, where Dr. Orna Guralnik navigates a thorny brew of recriminations, conflict and painful truths with four new couples. Guralnik delves into the crisis of a deaf man and his hearing partner torn between sexual freedom and commitment, a young couple haunted by trauma and buried secrets, a long-married pair trapped in cycles of bickering and avoidance and a therapist-writer duo locked in a zero-sum battle of sacrifice and grievance that pushes Orna to question her own methods.
