Learning to Breathe Again: Siobhan McKenzie’s Fragile Return to Holby

For years, Siobhan McKenzie has been one of Holby’s quiet constants — calm under pressure, reliable in chaos, the kind of presence that steadies a room without ever demanding attention. But since the night she was attacked, that certainty has been replaced by something far more fragile: the daily effort to feel safe in a world that suddenly doesn’t.

Her decision to go to a Sexual Assault Referral Centre was a brave first step, one taken in silence and without ceremony. She got through the examination, endured the clinical questions, and walked back out with the same resolve she brings to everything else. To anyone watching from the outside, it looked like strength. To Siobhan, it was survival.

What nearly broke her wasn’t the hospital corridor or the paperwork. It was a small, human gesture: the £20 note Flynn left so she could get a taxi home. Kindness has a way of slipping past armour, and in that moment, she couldn’t hold herself together. The tears came not because of the money, but because it was proof that someone saw how much she was hurting — even when she was trying not to show it.

Going back to work felt necessary. It also felt terrifying.

Holby is loud, unpredictable, and full of triggers she can’t control. She tells herself that routine will help, that doing the job she loves will anchor her again. But on the floor, the cracks start to show. A raised voice in reception makes her flinch. A crowded cubicle feels too small. During an examination, a sudden wave of flashbacks hits, pulling her out of the present and into a memory she doesn’t want to revisit. She pushes through, finishes the task, and keeps moving — because that’s what she’s always done.

Flynn notices the change immediately. His concern, however, doesn’t always come out gently. When he steps in to protect her from being hassled at reception, Siobhan insists she doesn’t want special treatment. She wants normality. She wants to be trusted to handle her job without being wrapped in caution. Later, when her focus slips, Flynn admonishes her, not realising how close she already is to the edge.

That tension — between wanting support and wanting independence — is at the heart of her story.6 major Casualty spoilers for 31 January | HELLO!

Siobhan isn’t trying to pretend the attack didn’t happen. She’s trying to prove it doesn’t get to decide who she is. But trauma doesn’t follow timetables, and it doesn’t disappear just because you put your uniform back on. The fear is quieter now, but it’s everywhere: in the way she scans a room, in how tightly she holds onto control, in the effort it takes to keep breathing evenly when memories intrude.

What makes her journey so compelling is its honesty. There’s no instant recovery. No dramatic breakthrough. Just a series of small, exhausting choices: to come back, to stay, to keep going even when every instinct says to run.

The real question isn’t whether Siobhan is strong enough to do her job.

She is.

The question is whether she’ll allow herself to accept help without seeing it as weakness — and whether she can learn that healing doesn’t mean erasing what happened, but learning how to live alongside it without letting it take everything else with it.

In Holby, emergencies usually announce themselves with sirens. Siobhan’s doesn’t. It arrives quietly, every day, in the space between memory and courage — and in her determination to keep showing up anyway.
