May 1914. Encouraged by politically aware chauffeur Tom Branson, the socially conscious Lady Sybil espouses politics as a means of aiding equality for women and the lower classes, to her father's anger. At a political meeting she is injured in a scuffle and rescued by Matthew. Lady Mary tells her mother she has received a marriage proposal from Matthew, but tells her mother she feels she should come clean about Kemal to him. Rumours about this indiscretion are now rife and Cora tells her mother-in-law how she helped Mary move the body. Edith continues to see more and more of Sir Anthony whilst O'Brien and Thomas continue to persecute John. They tell Carson they saw him steal wine and get Daisy to support them. However, Daisy does the decent thing and admits she was put up to it. Bizarrely, John, though he knows Thomas to be the wine thief, offers no explanation, confessing to being a former alcoholic and offering his resignation.
