"The Good Samaritan" is the 1030th episode of Casualty and the 26th episode of the 31st series. It was preceded by "It Starts With the Shoes" and followed by "Mobile". The episode was directed by Jo Johnson and written by Mark Catley. This episode marks the first appearance of the new, revamped entrance of the ED.
The Holby staff become increasingly concerned about David's manic behaviour when he impulsively buys a fancy car on the way to work, and behaves inappropriately at the pub. Concerned for his safety, a heavily pregnant Robyn takes it upon herself to intervene, and orders him to take her for a drive in his car.
Meanwhile, back at the ED, a man with potentially fatal burns is admitted after rescuing a fellow driver, Sally Hodge from her crashed car, and the gang prepares to throw a 60th birthday party for Duffy - even though she's actually 56.
Connie continues to struggle with Grace, who is unwilling to co-operate with her mother. Connie finds comfort in talking to Grace's friend Hugo. She turns her attention to him and even agrees to meet with him at the school, whilst Grace is with the childminder at home.
