Across the series

Beatrice arrives from rehabilitation in the opening episode and repeatedly disrupts Peter’s ordered life. Pregnancy and motherhood give her story greater responsibility without removing the volatility that makes her relationship with Peter so distinctive.

Relationship lens

Beatrice and Peter are bound by affection that neither experiences as simple. Her volatility challenges his preference for order without making her merely an obstacle.
