Season 15, Episode 39 - Mens Sana in Corpore Sano
As Oliver and Harry prepare presentations to compete for the next rotation on Darwin, Oliver reaches rock bottom as he stoops to stealing Tara's work and passing it off as his own. He finally faces up to his grief and his guilt over Tara and comes clean, exonerating Gemma in the process; he then bids Elliot and Holby a fond farewell before heading off to face his future.
Harry is indignant to hear how Gemma has been stitched up by Oliver. When an angry patient's relative forces him to look at his own approach to life, he discovers his better side when he offers to renounce his claim on Darwin in return for Oliver clearing Gemma's name.
Malick returns, planning to keep a low profile but immediately antagonises a patient and loses his nerve. But a comment from Arthur gives him the opportunity to give his patient a new lease of life - The Malick is back!
