While Joanna is extra careful to make sure that her and Statham aren't seen arriving together, Caroline isn't quite so lucky when she is spotted turning up with Guy after having spent that night at his place. Despite Caroline assuring everyone nothing happened between them, Guy is happier to play up to the rumours spreading around the hospital until Caroline forces him to admit the truth by digging up some dirt to blackmail him with. Meanwhile Martin is on the hunt for his missing soya yoghurt after it has been moved by the cleaners, Mac discovers that his old girlfriend is getting married, Statham spends the day enjoying how his white coat swirls around him, Sue tries to get her hands on Mac's hair and Harriet loses one of her many children.
