Thomas, the footman, continues to work with Cora's maid O'Brien to try to undermine the valet Bates, first attempting to frame him for stealing a snuffbox, and later for stealing a wine bottle. Bates is cleared of those crimes, but Anna, the head housemaid who is in love with him, discovers that he was arrested for stealing in the past. It turns out, however, that Bates' wife had actually committed the crime, and he took the blame for it. Bates seems to return Anna's affection, but the two have yet to act on it. Thomas attempts to steal the butler Carson's wallet, and Carson finds out. Rather than being fired, Thomas joins the Army Medical Corps, anticipating that World War I will soon begin.
