In Holby’s emergency department, chaos is normal. Pain is expected. Crisis is routine. But for Siobhan McKenzie, the danger no longer ends when her shift does. After the attack that shattered her sense of safety, the hospital she once saw as a place of control and purpose has become something far more complicated: a daily test of courage.

Siobhan’s decision to go to a Sexual Assault Referral Centre was her first act of reclaiming control. The examination was clinical, necessary, and emotionally draining, but she got through it. To the outside world, it looked like strength. To Siobhan, it was survival. Almost immediately, she made another choice that felt just as hard: she would go back to work.

For Siobhan, returning to Holby isn’t about pretending nothing happened. It’s about refusing to let what happened define every part of her life. Work is familiar. Structured. Predictable in a way the world outside no longer feels. But familiarity doesn’t mean safety, and the ED quickly becomes a place where memories and reality collide.

The smallest moments hit the hardest.

A raised voice in reception makes her tense. A sudden movement makes her flinch. And then there’s the quiet, devastating trigger she didn’t expect: the £20 note that Flynn leaves for her to get a taxi home. It’s a kind gesture, practical and thoughtful, but it opens the door to everything she’s been trying to keep locked away. She breaks down, not because of the money, but because it proves something she’s been denying — that she isn’t fine, and that someone else can see it.

Back on the floor, Siobhan does what she’s always done: she treats patients. She focuses. She pushes forward. But trauma doesn’t disappear just because you’re busy. During an examination, she’s hit by flashbacks so strong that for a moment she isn’t in Holby at all. The room blurs. Her breathing tightens. She forces herself to keep going, but the fear lingers long after the patient has left.

Flynn notices the change.

His concern, at first, comes out as frustration. When he sees her distracted and unsettled, he admonishes her, trying to pull her back into the standards the department demands. It’s not cruelty — it’s worry, badly expressed. But for Siobhan, it feels like another reminder that she’s failing at something she used to do effortlessly.

The real struggle isn’t her competence. It’s her capacity.

Siobhan doesn’t want special treatment. She doesn’t want softer shifts or sympathetic looks. She wants to be the person she was before — the one who could walk home without fear, who could focus without flinching, who didn’t have to measure every moment against a memory she never asked for. But healing doesn’t work on deadlines, and it doesn’t follow rotas.

When she’s told that the police don’t have enough DNA to identify her attacker, the disappointment cuts deep. It isn’t just about justice — it’s about closure, about the hope that something concrete could come from something so chaotic and violent. The news pushes her closer to breaking point, and when she hears colleagues casually talking about walking home, she finally tells them what happened to her.

It’s a turning point.

Not because everything gets easier, but because she stops carrying it alone.

Siobhan’s story isn’t about quick recovery or dramatic breakthroughs. It’s about the slow, painful work of learning how to live in a world that suddenly feels less safe than it used to. It’s about accepting help without feeling weak. And it’s about understanding that going back to work doesn’t mean going back to who you were — it means figuring out who you are now.

In Holby, emergencies are loud and urgent. Siobhan’s is quiet, persistent, and deeply human. And it may be the hardest one she’s ever had to face.
