Casualty has never been afraid to rip out the heart of Holby ED, and now whispers from behind the scenes suggest that the upcoming finale of the 12-part “Supply and Demand” saga could see not one, but two fan-favourite characters bow out for good.

Rumours Swirl After Ngozi’s Exit
Nurse Ngozi Okoye’s (Adesuwa Oni) emotional farewell has already left fans reeling, but insiders suggest she may not be the only character walking away from Holby. Her confirmed departure has opened the floodgates for speculation — and fans are convinced the finale could bring another wave of heartbreak.

With Sunny Callahan (Jamie Marie Leary) fighting for her life after the courtroom shooting, and Flynn Byron (Olly Rix) spiralling out of control, viewers are bracing themselves for more exits in the coming weeks.

Sunny’s Fate Hangs in the Balance

The most obvious candidate is Sunny, whose condition deteriorated dramatically after being gunned down by the drug gang she once worked for. Despite managing to confess vital information, she collapsed before doctors could save her. Spoilers have deliberately kept her survival ambiguous, fuelling fears that she will not live to see justice done.

For fans, Sunny’s potential death would be devastating, especially as her relationship with her son remains fractured. But with the finale promising “unmissable shocks,” many believe her death could be the emotional centrepiece of the arc’s conclusion.

Flynn on Borrowed Time?
Another name on the chopping block is clinical lead Flynn Byron. Arriving late, dishevelled, and distracted during the ED’s darkest hour, Flynn has angered colleagues and alarmed fans. His reckless behaviour has already drawn Dylan Keogh’s concern, and with rumours of yet another “big night” hanging over him, speculation is rife that Flynn’s storyline may end in disgrace or departure.

Could his career — or worse, his life — come crashing down in the finale?

Fans Brace for Double Heartbreak
Theories have exploded across social media, with fans predicting who will survive the finale:

“They won’t stop at Ngozi — Sunny and Flynn are both finished 😱.”

“Casualty never does one big exit… it’s always a bloodbath in the finale.”

“If Sunny dies and Flynn leaves, Rash and Dylan are going to be broken.”

A Finale Like No Other
The “Supply and Demand” arc has been one of Casualty’s most ambitious storylines in years, weaving drugs, shootings, romance, and heartbreak into a relentless 12-week rollercoaster. If rumours prove true, the finale could see two beloved characters exit, changing Holby ED forever.

For now, one thing’s certain: Casualty fans need to prepare themselves for tears, shocks, and a goodbye (or two) that no one will see coming.
