Violet is shaken when Kuragin confesses that he loves her and wishes to remain with her rather than locate his missing wife. The family then goes to London for Rose's wedding where her sour mother Susan makes it clear that she and estranged husband Shrimpy are only putting up a show of togetherness for the wedding and she is as disapproving of the match as Lord Sinderby. On his stag night Atticus is tricked into appearing shirtless with a prostitute and the photo sent to Rose. Anna and John are summoned to Scotland Yard and told that Green was well-known as a sexual predator though they feign innocence. Anna takes part in an identity parade and is released but later arrested, as she was seen at the spot where Green died. The others return to Downton for the unveiling of the war memorial.
