Learning Curve – Part Four (Season 40 Episode 4): Siobhan struggles to pick up the pieces in the wake of her attack
Siobhan struggles to pick up the pieces in the wake of her attack, and is forced to reveal what happened as the traumatic memories impact on her ability to work. Flynn overhears Stevie question Kim’s abilities, Dylan is unforgiving of Matty’s mistakes, and Faith pulls Iain aside to tell him she’s pregnant, but he reacts badly when she reasons that she cannot keep the baby.

The atmosphere at the hospital thickens as personal crises bleed into professional duties. Siobhan’s struggle for composure becomes a visible fracture; during a high-stakes trauma case, a sudden loud noise triggers a dissociative flashback, forcing her to step away and finally confess the assault to her supervisor. The revelation sends shockwaves through the department, shifting the staff’s focus from clinical precision to delicate empathy.
Meanwhile, the hierarchy begins to crumble under the weight of ego. Flynn’s discovery of Stevie’s doubt regarding Kim creates a toxic undercurrent of paranoia in the ED. Rather than confronting Stevie, Flynn finds himself caught in a moral quandary—whether to warn Kim or let the professional friction play out. This tension is mirrored in the surgical wing, where Dylan’s relentless pursuit of perfection turns into cold cruelty. Matty, already reeling from a minor clinical slip-up, finds himself isolated as Dylan’s unforgiving “teaching” style begins to look more like a personal vendetta.
The most visceral conflict, however, remains between Faith and Iain. In a quiet corridor, the air is heavy with the weight of her choice. Iain’s defensive reaction to the news stems from his own unresolved baggage, but his inability to support Faith’s autonomy leaves their relationship on the brink of collapse.
