After catching her husband Reece cheating, a woman collapses emotionally and refuses when he comes to pick her up. She cries all night; their daughter Celia comforts her, saying, "Dad's in the wrong. You don't have to forgive him." She later reaches out to Dorothy and Niamh and confesses, "Reece cheated on me." One of them admits they already knew. The revelation deepens her shock: a decade of marriage feels undermined, and the episode ends with her isolated and facing an uncertain next step.
