"The Final Word" is the 107th episode of Casualty and the third episode of the 8th series.
The funfair's in town and there's trouble looming. Jackie Walsh, a pregnant woman, is apparently a victim of muggers but when her brother Kevin turns up, it becomes clear that he is the mugger and she isn't the only victim of his twisted rage. The other problems appear to be in administration, where Mark's feeling the pressure Helen's settling in well and impresses both Charlie and Duffy. Ash finds it hard to accept Ken's appointment and Duffy doesn't know whether to tell Charlie that Ken is gay!
