Robert is summoned to America to bail out his reprobate brother-in-law Harold but, after Mrs Hughes has given her the 'official' version of Anna's rape, Mary steps in to let John stay with his wife with his place being taken by Barrow. Barrow is curious as to the change of plan, asking Baxter to find out more, which Molesley overhears. Isobel plans to go with Tom to a meeting addressed by a Liberal MP but stays behind to nurse flu-stricken Violet, and he goes alone, sitting next to Sarah Bunting, an attractive young woman. In London Edith decides she wants an abortion whilst Rose continues to see Jack Ross. Back at Downton, the pigs arrive and Mary takes Charles Blake to view them. He proves invaluable when the animals seem to be in trouble and he and Mary combine to save them, getting covered in mud in the process. Meanwhile Anthony Gillingham returns with Green, who faces Mrs Hughes' anger.
