Mary's new alliance has aroused Violet's interest in matters of suitability and love. With Sybil in mind, the Dowager Countess declares, "war breaks down barriers and when peacetime re-erects them, it's very easy to find oneself on the wrong side." Indeed, among war's greatest casualties at Downton are the prescribed roles and class boundaries. Thomas is exerting his authority over the servants with aplomb; Mrs. Patmore, Daisy and Mrs. Bird are cooking up a little something on the side; and Ethel has discovered an age-old way to support the war effort. But between Robert and Bates, faith and loyalty transcend class, offering hope when Robert needs it most. Because now, the war has threatened a far more serious casualty.
