Season 5 of the period drama begins in early 1924; and sees the Crawley household upended by changes roiling British society as a whole. The election of a working-class prime minister, for instance, precipitates Robert (Hugh Bonneville) being snubbed by the townsfolk when a committee is formed to build a war memorial. In years past, of course, he would have been its chairman?as Carson (Jim Carter), who's asked to lead it, knows. It's an uncomfortable position for both men to be in. The memorial brings with it another storyline: Mrs. Patmore (Lesley Nicol) wants her nephew, who was shot for cowardice, to be included, but Carson thinks not. Edith (Laura Carmichael), meanwhile, tries her best just to cope: As the season begins, there's still no word from or about Gregson, her married beau who left for Germany in 1922; and, due to the scandal an out-of-wedlock child would bring, their daughter is being raised by a tenant farmer and his wife. Thomas, as per usual, plays a part in some of the drama: His threats lead Miss Baxter (Raquel Cassidy) to confess to Lady Cora (Elizabeth McGovern) about her past. The ill-will between them doesn't stop her from intervening when she suspects he's harming himself, however. She also finds herself a witness in the ongoing Scotland Yard investigation about Mr. Green's death; and is wooed by Mosley (Kevin Doyle). Romance is in the air for others, too: Mary (Michelle Dockery) enjoys a getaway with Lord Gillingham, but has second thoughts about their relationship; Rose (Lily James) falls for a dashing young man named Atticus Aldridge (Matt Barber), though his being Jewish doesn't sit well with some; Tom enjoys the company of Sarah Bunting (Daisy Lewis), a teacher whose radical views upset Robert; Violet (Maggie Smith) is reunited with an old beau now facing hard times; Cora is hit on by an art historian; and none other than Isobel (Penelope Wilton) receives a marriage proposal.
