Casualty 2025 — January

Off Duty — Saturday 28 December 2024, 9.15pm, BBC1 and BBC iPlayer

Okay, technically Off Duty is not a 2025 episode, but as the opener of the latest 11-part boxset Public Property came within spitting distance of the New Year, we’ve decided to include it here for coherency.

The first half catches up with professional pressures and personal conflicts at the ED – including hostilities between Siobhan McKenzie and Stevie Nash over the clinical lead position. The second part involves the powerful juxtaposition of Jan giving trainee paramedic Indie (show newcomer Naomi Wakszlak) a reality check, while an off duty Dylan Keogh and Jodie Whyte are caught up in a tragic incident at a restaurant.

With hard-to-watch frontline emergency medicine and something to say about the expectations placed on medics at its core, this is Casualty at its finest and a great start to a new chapter in the show’s history.

Guest stars: Jack Wilkinson, Allyson Ava-Brown, Omolabake Jolaoso, Norman Murray, Isaiah St Jean and Harriet Luker.

Out of Time — Saturday 08 February 2025, 9.10pm, BBC1 and BBC iPlayer

Picking up directly from last Saturday’s arresting development, tonight Dylan is hauled into Holby Police Station in handcuffs and given a grilling over multiple patient deaths, his sobriety, and Thea Bayliss’s catastrophic car crash injuries. Incandescent with indignation, Dylan (never change!) doesn’t exactly help himself and ends up being held for 24 hours. Meanwhile, a lot is happening outside the clink. [Deep breath] Sophia books a termination, Nicole is sectioned, Rich and Siobhan’s son hits on Stevie (no, not a typo!) and drama-magnet Jodie dines on some just desserts in deliciously dramatic scenes – and that’s only the half of it!

Elsewhere, Stevie Nash makes peace with her head and her heart, but what does that mean for the consultant’s future in Holby? And Rash Masum tries to keep family ties from fraying permanently, but no good deed goes unpunished…
