When Casualty returns on January 10, Dylan Keogh is predicted to find himself at the centre of a crisis that no amount of experience can fully protect him from. Known for his sharp wit and resilience, Dylan enters the shift already drained — and the pressure never eases.

Early signs suggest Dylan makes a critical clinical call under extreme time pressure. At first, the patient stabilises, and the ward moves on. But as the episode progresses, it becomes clear something vital was missed. The real danger isn’t the mistake itself — it’s the moment Dylan realises reporting it could cost him everything.

Instead of immediate confession, silence sets in. Guilt builds. And the weight of knowing one wrong decision may have irreversible consequences begins to fracture the doctor who once held Holby together with humour and grit.
