The Biggest Casualty Exits We Could See in 2026
After Ngozi’s tragic death and Charlie Fairhead’s emotional farewell, fans know one thing for certain: no character in Holby ED is ever truly safe. With Casualty set to return at Christmas before heading into its landmark 40th series, speculation is already growing about who could be next to leave. Here are some of the most talked-about potential exits in 2026.
Faith Cadogan
Faith’s storyline has been one of rise and fall. Her addiction struggles, turbulent romance with Iain Dean, and increasingly strained relationships in the ED leave her in a precarious position. Many fans believe her story may have run its course, and an exit could be the natural conclusion to her arc. Whether it’s redemption or tragedy, Faith is firmly on the list of possible departures.
Flynn Byron
Since arriving as Clinical Lead, Flynn has been at the centre of controversy. From inappropriate behaviour to medical mistakes, his future looks shaky. While Dylan Keogh has tried to guide him, Flynn’s demons could ultimately push him out of Holby. His exit — whether by resignation, dismissal, or something more dramatic — would not only shock viewers but also reshape the ED’s leadership.
Iain Dean
One of the show’s most enduring paramedics, Iain has endured trauma after trauma, from personal loss to suicidal despair. While fans adore him, questions remain about how much more the character can endure. Could 2026 finally bring Iain’s long-teased departure — perhaps with a bittersweet exit alongside Stevie or a decision to walk away from HART for good?
Stevie Nash
Though she’s currently thriving, Stevie is another character whose story could take a sharp turn. As a strong female lead, she has quickly become central to the ED. But in Casualty, central characters often face the biggest shocks. A dramatic storyline — whether professional scandal or personal tragedy — could set up an unforgettable exit.
Dylan Keogh
With Charlie gone, Dylan has stepped into a mentor role that fans adore. But William Beck has played Dylan for over a decade, and fans quietly wonder how long he will stay. An exit in 2026, whether temporary or permanent, would be seismic. Dylan’s departure would mark the end of an era and leave Holby searching for another anchor.
Why exits matter
Exits in Casualty are more than cast changes — they reshape the ED, open new storylines, and keep the show unpredictable. From Noel’s sudden death to Connie’s fiery leadership battles, departures force both characters and fans to confront change. In 2026, as the series approaches its 40th anniversary, producers may be tempted to deliver one of the show’s biggest shocks yet.
The verdict
Faith, Flynn, Iain, Stevie, Dylan — all are at risk as Casualty moves into a new era. While nothing is confirmed, speculation will keep fans buzzing until official announcements are made. One thing is certain: Holby ED never stays the same for long, and 2026 could bring exits as shocking as any in the show’s history.
