When Tristan Wood’s mistress Jemima was brought to Holby last week with a head injury, Dr Zosia March suspected the hospital chairman of abusing her. But Zosia’s bid to help Jemima this week has devastating consequences.

Tristan and Zosia’s dad Guy Self are in high spirits as they plan to unveil Guy’s new neurosurgical unit at a glitzy gala that evening. Acting CEO Ric, meanwhile, wonders what the new unit means for other departments. And he’s right to worry when Tristan gives him an ultimatum…

Tristan’s buoyant mood changes when Jemima says she’s leaving him, and an angry Tristan physically assaults her. Jemima is then brought onto Darwin – but when tests reveal Jemima’s pregnant, Guy soon works out Tristan raped her. Guy tells Jemima she can’t stay with a rapist… and Zosia overhears!

Later, while Tristan and Guy are at the gala, Jemima confides in Zosia that she was trying to flee to France, but Tristan took her passport. Zosia goes straight to Tristan’s office to retrieve it – but when Tristan catches her in the act, he tries to stop her with brute force. Can Zosia defend herself?

Also, Serena has a one-night stand with old flame Robbie and is shocked to discover he has a suspected cancerous lump. It almost looks like Serena might consider giving things with Robbie another go – but will her feelings for Bernie scupper any chance of a reunion?
