"My Last Day - Part One" is the 656th episode of Casualty and the 18th episode of the 23rd series.
Jessica is stunned when Sean confronts her about the affair with Adam. She confesses all and tells him the baby is definitely his, and is relieved when he forgives her - or so she thinks. At the hospital, a journalist arrives to talk about an old man found badly beaten in the street, but soon takes more of an interest in Toby's apparent incompetence in treating the patient. Meanwhile, Zoe gets to the bottom of the hit-and-run and Ruth refuses to treat a patient because he has bought a mail-order bride from Thailand.
