In a devastating turn of events that will shake Holby City Hospital to its core, next week’s Casualty will see Clinical Lead Flynn Byron unravel under the weight of secrets, staff mutiny, and one deadly lie that could cost a young woman her life—and Flynn everything he built.

The episode, titled “Supply and Demand,” will air this Saturday and promises the most explosive Flynn storyline since his arrival.

💥 The Collapse Begins: A Dead Teen and a Cover-Up

The crisis starts when a 19-year-old patient, previously treated and discharged during the overdose surge, is rushed back into ED in full cardiac arrest. Despite efforts from Faith, Dylan, and Ngozi, she dies within minutes.

The truth is horrifying: she was cleared under Flynn’s new rapid-discharge protocol, a desperate attempt to ease bed shortages and drug use congestion.

“She wasn’t ready to leave,” Faith screams. “You sent her out there to die!”

Flynn, under pressure, tries to deflect blame—claiming it was a team decision. But CCTV footage, logged vitals, and witness testimony point clearly to him overriding standard procedure.

🧠 Dylan Confronts Flynn: “You’re Playing God”

Already seething from their ethical clash over naloxone distribution, Dylan Keogh finally snaps and confronts Flynn in front of senior staff.

“You’re not saving lives. You’re mass-managing death and hoping no one notices.”

Flynn fires back, accusing Dylan of protecting Ngozi despite knowing she’s unfit to work. The two come dangerously close to a physical altercation before Jan Jenning steps in.

But the damage is done. Dylan files a formal complaint. An emergency board review is triggered.

🚨 Siobhan Joins the Rebellion: “You’re Not My Leader”

Senior nurse Siobhan McKenzie, previously neutral, finally takes a stand—publicly defying Flynn’s authority during handover. She instructs junior staff to follow clinical instinct over “his shortcuts.”

“I don’t take orders from people who don’t believe in patients.”

Her quiet revolt sparks an unofficial staff boycott—dozens begin logging anonymous concerns, and staff whisper of a no-confidence petition forming.

📉 Flynn’s Reputation Collapses in Real Time

What follows is a domino effect:

• His past leadership decisions are unearthed—including a similar incident at a previous trust that was buried.

• A junior doctor reports that Flynn encouraged them to falsify discharge times during the crisis to “keep metrics up.”

• A furious parent arrives in the waiting room, claiming Flynn refused to admit her daughter hours before her collapse.

The entire department turns cold.

Flynn, once polished and composed, is seen disheveled and panicked, standing alone in his office as the walls begin to close in.

“They want my head,” he mutters. “They think I’m the problem.”

🔚 The Final Blow: An Email That Destroys Him

In the final moments of the episode, Flynn receives an email. His eyes scan the screen. His face goes pale.

“URGENT: Suspension Pending Investigation – Holby ED Clinical Review Board”

He slams his laptop shut, just as a figure appears at the door: Teddy Gowan.

“You told me you were protecting the team. But you were protecting yourself.”

Flynn doesn’t respond. The episode ends with Flynn alone, shaking, finally realizing: his empire has
