Momentum was the thirty-fourth episode of Series 25 and the 764th episode of Casualty overall.

Plot

Polly has been stabbed by the unstable Hannah and is bleeding in the basement. Hannah finds Dylan to explain but he won't listen. And he's hidden his dog, Dervla, in the basement, so is reluctant to let anyone go down there.

Dylan becomes concerned when Polly fails to return his calls and, when her phone is found in Hannah's cubicle, Dylan confronts Hannah, who pulls a bloody knife on him. Alarmed, he orders Jay to go down to the basement... Polly's been hurt.

Will the medics find Polly before her life ebbs away? And how will the day's tumultuous events impact upon Jordan's career prospects?

Chronology

Behind the Scenes

Real-time

This episode is unique in the fact that it took place in 'real-time'. This means that instead of episode cutting between points of time in the day, it covers a continuous period of 50 minutes (the length of the program). Because of this unique perspective, the camera had to follow characters as they walked though the department, allowing viewers to see certain areas of the hospital for the first time. One such area is the corridor linking the main ED to the Clinical Decisions Unit (CDU).

Time of Airing

It is believed that this episode was intended to air at 21:00. This is because Polly's time of death is declared at 21:42, exactly 42 minutes into the real-time episode. The episode in fact aired at 21:20, meaning the in-universe timings were behind by twenty minutes.
