Thor Lundgren

Thor is a nurse in the emergency room at All Saints, working the same chaotic shifts as Jackie Peyton. Big-hearted and unflappable, he brings warmth and gossip to the nurses' station, dishing about celebrities and love life even as the ward around him falls apart. He is the friend who keeps things human.

Stephen Wallem plays him with such open, unguarded delight that he becomes the show's pressure valve — a burst of genuine sweetness in a series built on compromised people. His comic timing never curdles into caricature; underneath the camp there's real steadiness, someone you'd actually want holding your hand in a crisis.
