As Matthew and Isobel, the newly-arrived Crawleys settle into life in the village, Isobel offers her experience with modern medical techniques at the hospital, to the considerable consternation of Violet. Both Matthew and Mary bristle at the prospect of being matched to one another; still, Matthew indulges Mary’s clever barbs even as a suitor in the form of Evelyn Napier is invited for a foxhunt, accompanied by the handsome attaché at the Turkish Embassy, Kemal Pamuk.
Downstairs, secrets reflect the ambitions, shames and desperate hopes of the servants, as housemaid Gwen tries to hide the contents of a heavy box set atop the wardrobe in her room; Carson abandons his customary dignity as he skittishly raids the pantry; and Bates refuses to share the source of his debilitating pain to his co-workers. Their concern and camaraderie markedly contrast the festering discontent of Thomas and O’Brien.
A sinister stranger barges into the house, demanding to speak to Lord Grantham, and an attractive stranger captivates Mary before setting into motion a chain of events that put the fate of Downton Abbey on even less stable ground.
