The simmering dispute between Isobel and Lady Cora comes to a head. When Isobel learns Cora has re-arranged the meal times for the servants and the work schedules for the nurses without consulting her, she suggests that if she is not to have a meaningful role, she will leave. Cora tells her that may be a good idea and Isobel heads to France. With Isobel away, her servants try to keep themselves busy. Her cook takes to feeding unemployed ex-servicemen but O'Brien, always bent on causing trouble, it seems, tells Lady Cora but she doesn't quite get the reaction she was expecting. Robert meanwhile learns that Bates is working in a nearby pub and pays him a visit. Branson the chauffeur tells Lady Sybil that he is in love with her and he will only leave when she is ready to leave with him. Lady Mary decides that she will marry Sir Richard Carlisle. When housekeeper Mrs. Hughes finds Ethel in bed with one of the patients, she fires the housemaid on the spot and sends her packing without a reference. Everyone at Downton Abbey is worried when Matthew and William are reported as missing in action.
