BBC Casualty’s Flynn Byron, played by Olly Rix, is set to face a major decision after discovering the alleged inappropriate behaviour of his father-in-law, Mr Whitelaw, portrayed by Robert Bathurst. Recently, viewers have seen Rida Amaan, played by Sarah Seggari, struggle with the consultant’s actions.

In last week’s episode, nurse Amaan tried to confide in the emergency department’s clinical lead, Flynn, but was taken aback when Dr Byron revealed that Whitelaw was his father-in-law. Surprised by this revelation, Rida quickly changed the subject and complimented her new boss instead.

However, in this week’s episode, Rida gains access to a private chat room that reveals the misconduct of surgeons not only at Holby City Hospital but nationwide. After sharing her concerns with friends Jodie, played by Anna Chell, and Cam, played by Barney Walsh, she decides to make the group public, much to the chagrin of her colleagues.

Rida and her female co-workers from the surgery unit are summoned to Russell’s office, where he assures them they are safe. While Nicole, played by Sammy T Dobson, tries to voice her concerns, Rida silences her and later explains that this was part of her strategy to win Russell over.

Audiences should brace themselves for a jaw-dropping plot twist in the next instalments, as Olly shared with the Mirror some gripping details about his character’s upcoming trials. “That becomes really the sort of centrepiece of the box set, and that and that moral dilemma,” Olly disclosed.

He added: “I think what you’re seeing being set up and something that we really explore is ‘Who is this man? When the chips are down, what does he do? Is he brave? Despite personal consequences, does he tugtail and run?’

“We’ve introduced this high-functioning, very competent alpha-male personality who’s come from that world, and we’re asking now, ‘Can you do it when it counts?’”

The drama escalates when Russell gives Flynn an earth-shattering ultimatum – confess about his misdeeds and he’ll ensure Flynn never reunites with his wife Claire and their kids or use Flynn’s past infidelity in the military against him.

“That’s really the kicker – Russell can potentially leverage Flynn’s silence,” Olly hinted, before dropping another bombshell. “They’re not actively at war, they’re not fighting. He’s saying, providing you don’t do anything, I won’t do anything. Flynn has to choose to step into that fire and say ‘I’m going to risk it all, or he won’t.”

Last weekend, viewers of the popular medical drama were left heartbroken by the death of Cara, a character who had been undergoing cancer treatment. Cara’s demise came unexpectedly after she initially planned to return home, but then suffered a seizure and sadly passed away.

Olly also spoke fondly of the on-screen conflict between Flynn and Dr Rash Masum, embracing the dramatic tension it brought to the series. The actor recounted: “I enjoyed it from the off.

“I liked that I sort of put his nose out of joint initially, as an actor, it was an interesting thing to do. I was hoping that we would get the payoff that I think we’re going to get. Ultimately, there’s no lack of professional respect or courtesy, yes, he quite brutally fired somebody and that upset Rash.

“But I think all Flynn is ever asking of Rash is that he steps up and gives his best because he’s such an outstanding doctor. I think Flynn, from the off, sees something worth nurturing in Rash and tries to bring out some self-belief and self-confidence as the ranking elder.”

One thing Olly is certain about is that Flynn can hold his own. “He can own his failings, he can own his blind spots and face them,” he said. “He does have a sort of energy that means he can attack things pretty aggressively and pretty quickly, often pretty effectively.

“But he’s not afraid to confront his failings. Of course, it’s gathering pace in the background but that becomes a central question of the entire box set. Is his biggest failing and biggest issue – is he going to face those? We’re seeing good signs so far, but we’ll see.”

He also teased an “interesting story” about Flynn and councillor Anna Mills, whom he has been seen getting close to in recent weeks.

After joining the BBC medical drama earlier this year, Olly admitted it was a “collaborative process” between himself, series producer Liza Mellody for Olly to step into the role of Flynn. “The character himself, we had such an exciting conversation about him,” he revealed, admitting he “threw suggestions in” for his character.

Olly’s preparation for his role involved drawing on special forces inspiration, reflecting Flynn’s military past. His debut episode uniquely presented Flynn’s perspective as he entered the scene as a patient after a car crash.

Discussing his character, Olly remarked: “Flynn doesn’t come in like any good character, he doesn’t come in static or fully formed, unevolving entity. If the audience sticks with him and goes with him, they’re going to go on a journey. That’s why we did the research and the character we began to wrench him out of that context and put him in an NHS world and people that he has to treat very differently, and watching him discover himself in a new environment. It becomes a bit of a redemption arc for Flynn.”
