Chaos at Holby: Hungover Nurse Puts Patients at Risk in Explosive Casualty Episode
In the latest installment of Casualty, titled “Supply and Demand,” the tension reaches boiling point when a trusted nurse arrives to work visibly hungover, putting herself, her patients, and her colleagues in serious jeopardy. The storyline, which plays out with a mix of dark humor and gut-wrenching consequences, is a gripping portrayal of how personal struggles can spiral into professional disaster — especially in the high-stakes world of emergency medicine.

🛌 Trouble at Shift Start
The episode begins on a typical busy morning at Holby City Hospital’s Emergency Department. But things quickly unravel when Nurse Maisie Clarke staggers through the staff entrance, clearly worse for wear. With bloodshot eyes, trembling hands, and slurred speech, her behavior immediately raises alarms.

It doesn’t take long for her colleagues — particularly Faith Cadogan and Rash Masum — to notice something is wrong. When Maisie mislabels a patient’s chart and nearly administers the wrong medication, Faith pulls her aside.

Maisie, attempting to laugh it off, insists she just had “one too many” the night before and didn’t get enough sleep. But the damage is already done, and her instability begins to ripple across the ED.

🧑‍⚕️ The Cost of a Mistake
The most alarming moment comes when Maisie is left to monitor Elliot Warner, a diabetic teenager brought in after fainting at school. In a moment of distraction — and clearly battling nausea and disorientation — Maisie fails to notice his blood sugar levels crashing.

By the time Rash returns to check on Elliot, the boy is unresponsive. Panic spreads across the unit as the team scrambles to stabilize him. Thankfully, Elliot is saved, but the near-miss sends shockwaves through the department.

Faith confronts Maisie again, this time not with suspicion but concern: “This isn’t just a hangover, is it?” Maisie finally breaks down, revealing that she’s been drinking more heavily since the death of her brother — a trauma she’s been hiding behind a façade of professionalism.

🍷 Addiction in Plain Sight
The writers of Casualty skillfully weave this personal revelation into a broader commentary on addiction and the hidden struggles of healthcare workers. The pressure to remain strong and composed, even while coping with immense personal pain, is something many professionals quietly endure.

Maisie’s situation also highlights how warning signs are often missed — or ignored — in environments that demand constant performance. Her breakdown becomes a turning point, both for her character and the team that surrounds her.

🧠 Workplace Ethics & Responsibility
The hospital is thrown into crisis mode as clinical lead Max Cristie investigates the incident. A formal report is filed, and Maisie is suspended pending review.

“I’m not here to punish you,” Max tells her. “But we can’t pretend this didn’t happen. You need help — and so do we, as a department, to ensure this doesn’t happen again.”

The episode doesn’t shy away from the ethical dilemma: Can someone in crisis be trusted in a role of care? And when is it time to speak up before mistakes become tragedies?
