Downton Abbey

1925. Big changes are afoot. Robert anticipates having to cut costs, and reduce the size of the staff, which worries Carson. Mrs Hughes is nervous about being embarrassed when performing her wifely duties when married to Carson, and asks Mrs Patmore to sound him out; after much embarrassment, Carson says he expects them to have a full marriage, which reassures Mrs Hughes. The local hospital is threatened with a take-over by the larger County Hospital; the board is split, with Violet objecting, and Isobel approving in the name of efficiency. A former chambermaid, Rita Bevan, turns up trying to blackmail Mary by revealing her tryst with Lord Gillingham. Mary refuses to pay, but Rita confronts Robert, who buys her off with £50 instead of the £1,000 she wanted, and gets a signed confession to prevent further blackmail. He admires Mary's pluck, and approves of her taking over Tom's job as the estate's Agent.Sergeant Willis tells Bates and Anna that a woman has confessed to killing Green, and the matter is closed. Anna is upset at not having a child; twice she was convinced she was pregnant, but it was a miscarriage each time. Edith plans to spend more time in London, and be more hands-on with the publishing business. The family attend an auction at a neighbouring estate which is being sold off. Daisy unwisely confronts the new owner because her father-in-law Mr Mason may lose his farm, but this backfires, and she only succeeds in angering him. Although she is liable to dismissal, Cora keeps her on. The owner tells Robert that great estates like theirs are on the way out, and advises him to sell up too.

1925. The acid-tongued exchanges between Violet and Isobel over the hospital get sharper; Cora sides with Isobel. Mary chides Robert for offering Carson the servants' hall for his wedding reception, and offers upstairs instead; Mrs Hughes insists on a separate venue, which leads to friction between the couple. Thomas looks for another job; he thinks it's clear that people are avoiding him, and want him gone. Edith argues vehemently with Mr Skinner, the publisher of her magazine, who dislikes all her ideas. Mary takes Anna to a Harley Street doctor, who proposes an operation during her next pregnancy.Mary arranges for the pigs to be entered in the local livestock show, but unwisely takes Marigold when she goes to inspect them on the farm, which upsets Mrs Drewe tremendously. During the show, she kidnaps Marigold and takes her home; her husband persuades her to give her back, and decides it would be best if they moved away. Robert is distressed, because of their long and loyal service, but reluctantly agrees.

May 1925. Cora, told by Mrs Patmore that Mrs Hughes is unhappy with having her wedding breakfast in the hall, forces a meeting with the family so that Mrs Hughes can explain, and supports her, so Carson gives in. Violet tries to get Robert to support her view on the hospital merger; at a meeting of the Board things get nasty, and Isobel is annoyed enough to be rude to Dr Clarkson. Edith has more arguments with the publisher of her magazine, and he walks out. Fortunately, she meets an old acquaintance, who helps her produce the next issue. Anna is pregnant, so Mary plans to take her to the doctor in three months time. Thomas travels to be interviewed by an eccentric widower, Sir Michael Reresby (Ronald Pickup) in decrepit Dryden Park, but declines the position.Violet's butler, Spratt, is behaving strangely, which catches Denker's attention.

At the wedding breakfast in the village school, Tom Branson and his daughter arrive unexpectedly from Boston; he announces he feels Downton is his home, and wants to stay.

1925. Lady Shackleton visits with her nephew Henry Talbot, a racing car driver and another old friend of Mary's. Violet wants her support in the dispute over the hospital, and explains that her reason for opposing the merger is her resentment at the government taking over more and more things instead of leaving it to the locals, which rather mollifies Isobel. Lady Rosamund also visits, and is visited by Mr and Mrs Harding in connection with a women's college of which she is a trustee. Mrs Harding turns out to be Gwen, the former housemaid who left to better herself; the family are pleased for her. Sergeant Willis asks Miss Baxter to testify against the man with whom she was involved when she stole from a previous employer; she is afraid, but Molesley encourages her, and she agrees.

Carson is not happy with Thomas, while Mary and Edith hope to overcome their past and find new happiness with the men in their lives.

A suspicious Violet goes to confront Amelia, and accuses her of wanting Isobel to marry Lord Merton and look after him in his old age. The family watch Henry in a motor car race, but his friend Charlie is killed in a crash. With the entire family in shock, Mary takes a call from Henry, who implores her to give her an answer to his advances; she says no, as he is not the right type for her. Daisy and Molesley sit their exams; the latter does so well that the headmaster offers him a teaching job at the school. He also offers to help Andy learn to read, when his problem is revealed.
