November 1918. Believing her marriage to have been a sham, Daisy is reluctant to accept a widow's pension whilst Robert writes to the father of Ethel's child, only to learn that he was killed in the war. As the Armistice is announced a Canadian soldier, suffering terrible burns, comes to recuperate and declares that he is Patrick, the heir presumed dead on the 'Titanic' and until recently an amnesiac. Only Edith believes him. Carlisle plans to buy a house near Downton and poaches Carson as his butler. He also notes Mary's devotion to Matthew and threatens to expose her affair unless she proves a loyal wife. John returns from a meeting with Vera in London, with a cut on his face.
