Lady Sybil expresses her interest in politics to Lord Grantham, who isn't at all pleased to hear of her venture to the debate, and things take a drastic turn when she's injured at the bi-election results. Meanwhile, Lady Mary and Matthew continue to get closer, leading to a proposal of marriage, much to Cora and Violet's delight. However, the events surrounding Mr. Pamuk's death may put a spanner in the works.
Thomas continues his campaign to get rid of Mr. Bates from Downton with the help of O'Brien and a misguided Daisy by accusing him of stealing the wine from the cellar.
Two men vy for Daisy's affections, wanting to take her to the fair, while Sybil helps Gwen in her search for a new job. Violet has a favour to ask of Matthew. Mrs. Hughes takes an evening off to spend time with an old flame.
News of the Titanic's sinking has just reached Downton Abbey, causing much chaos within the family as Lord Grantham has three daughters and no male heir. His only two heirs went down with the ship, including Patrick Crawley, who was to marry Lady Mary, the Earl's eldest daughter. With both heirs now dead, the Crawley girls must find husbands of their own as the entire estate is entailed away from the female line; however, perhaps there is hope after all as Matthew Crawley, a third cousin, once removed is now heir to the title and the estate. The Dowager Countess of Grantham and Mary's mother, Cora, make it quite clear that Mary is to try her hardest to secure cousin Matthew as a husband in order to save everything.moreless
