The Casualty fandom is buzzing with theories after the latest trailer dropped, and one prediction is rising above the rest: could Iain Dean (Michael Stevenson) be about to take a bullet in this Saturday’s explosive episode?

Eagle-eyed viewers have pointed out a fleeting but powerful moment from the trailer: Faith (Kirsty Mitchell) in floods of tears, her heartbreak raw and unmistakable. Fans are now convinced this emotional breakdown can only mean one thing—something catastrophic happens to Iain during the dangerous police raid teased in recent storylines.

Iain has always lived life on the edge, balancing his role as a paramedic with his increasingly perilous ties to the HART team and their high-risk operations. But as Holby’s drug dynasty storyline reaches its bloody climax, speculation is rife that this time, Iain may not walk away unscathed.

“IAN will get shot, can just see it,” one fan wrote online, echoing the fears of countless others who dread that the show’s much-loved hero could be in the firing line. With bullets flying, criminals making a desperate last stand, and tension sky-high, the set-up certainly seems perfect for tragedy.

Faith’s tears are fuelling the rumours even further. Having only recently discovered Iain’s dangerous double life, she is already torn between love, fear, and betrayal. If the man she cares about is gunned down before her eyes, the fallout would be devastating—not just for her, but for the whole ED.

Of course, Casualty is notorious for misdirection, and trailers often hint at tragedy without giving away the full truth. Could Faith’s breakdown be linked to another shocking twist entirely? Or will this be the moment fans have dreaded—when Iain finally pays the ultimate price for his relentless heroism?

What makes the rumours even more gripping is the question of survival. If Iain is shot, will he survive his injuries? Or could Casualty be preparing fans for one of the most heartbreaking exits in recent memory?

One thing is certain: this Saturday’s episode promises to be an unmissable rollercoaster, filled with gunfire, heartbreak, and the kind of high-stakes drama that has kept Holby viewers hooked for decades. Whether Iain walks away or is carried out on a stretcher, fans will be left shaken.
