Darwin is on shaky ground, but Hanssen pushes Sahira to get behind the cardiac trauma unit in an effort to save the department and keep her job safe at Holby. After a visit from Sir Fraser, Hanssen chooses to showcase a multi-disciplinary operation. In doing so he ignores the real challenge, and when the showcase doesn't go his way he is forced to make some ruthless decisions about a way forward for the hospital. Chrissie is determined to do better at her studies for the nurse practitioner assessment. She snaps up Malick's offer of help. When Dan hears of their budding friendship he makes an effort to pull her back into his arms. But will Chrissie be so easily swayed? When Sacha hears that Chantelle is no longer required, he offers to be the one to tell her, fearing that Eddi might not have the tact he does. But Sacha soon realises that telling Little Miss Sunshine that she doesn't have a job anymore is not quite as easy as he had hoped.
