With the house no longer a hospital Thomas hopes to make money on the black market but is ruined after being cheated by his supplier. Mrs Hughes helps Ethel to confront Mr and Mrs Bryant, the parents of her baby's late father but, whilst his wife seems moved, Bryant dismisses Ethel as a liar and fraud with no proof of paternity. Carlisle tries to bribe Anna to spy on Mary but she refuses and tells Mrs Hughes and Carson, the latter consequently withdrawing his offer to work for Carlisle, whom he sees as underhand. Robert, disillusioned by the war's failure to accomplish anything, makes a play for Jane but quickly apologises whilst Sybil, liberated by her war work, elopes with Tom Branson, though her sisters follow and bring them back. John is concerned that, whilst Vera officially killed herself by taking poison, it was rat poison bought by him and fears he may be incriminated. The big news, however, is Matthew regaining the use of his legs. He announces his forthcoming wedding to Lavinia but Violet tells him he is marrying the wrong woman.
