Set circa July 1917. The village hospital is not large enough to accommodate the large influx of wounded soldiers coming back from the front so Downton is turned into a convalescent home for many of them. O'Brien is shocked that Isobel Crawley seems to be giving most of the orders while Cora is relegated to the background and suggests that Thomas might be able to aid her from his position at the hospital. Violet strongly believes that Mary and Matthew are still very much in love and so, with the help of Rosamund, tries her best to end Matthew's engagement to Lavinia. She is also still convinced that there is much more to Lavinia's relationship with Sir Richard than meets the eye. Meanwhile, Anna runs into Mr. Bates in the village and they feel they may have a future together but, back at Downton, things are more highly charged as William asks a question of Daisy just before heading off to war and Mrs. Patmore reacts very badly to a chance remark. And what exactly is Branson up to? Whatever it is, it looks like it may cause trouble for Lord Grantham.
