S03E08 Episode #3.8
Carson promises Thomas that if he resigns, citing John's return as the reason, he will give him a good reference. However, O'Brien persuades Jimmy to tell the butler that he will call the police unless the reference is withdrawn. Violet's great-niece Rose comes to stay, apparently bored with London, though she is keen to accompany Edith to town for a day, staying with Rosamund. However, she gives them the slip to go to a club with her married boyfriend who was the reason her mother sent her to Violet, and, along with Matthew, they lean on her to return.
