Dawn Stratton became Andy's police partner in 2009.
Dawn and Andy were called to a disturbance at a student house on Gabalfa Road in which a young girl had been bitten. The perpetrator had been locked in the cellar of the property. While attempting to handcuff the man, Dawn was bitten on the hand.
Dawn knew there was something wrong with him, noting that she had seen corpses which had looked healthier. Leaving the house, the officers were met with the sight of carnage - "zombies" feasting on people in the road. She grabbed Andy by the arm and they ran back to the car.
With Dawn's condition worsening to the point that she was losing consciousness, Andy attempted to get her to St Helen's Hospital but was unable to do so. Andy decided to take Dawn back to Cardiff's Central Police Headquarters, where she could be examined by a doctor. Almost running down Sophie Gould on the way, Andy offered her a lift. He arrived at Police HQ with Dawn and Sophie to find the building under siege and, with the dead closing in, quickly sped away.
Following the advice of Gwen Cooper, Andy returned to his apartment block where Sophie helped him carry Dawn up the stairs to his flat. To the best of his ability, Andy cleaned, disinfected and bandaged Dawn's hand.
Dawn arose from settee and approached Andy in the kitchen, where he was making cheese on toast. A growl growing in her throat, fingers hooked into claws and drool dribbling from her curled lips, she shuffled towards him. Andy initially went for the cheese knife, then realised what he was doing and attempted to calm her by shouting her name. She leapt at him, knocking him to the ground and snapping at his face. Sophie used a towel to try and knock Dawn off balance and they both tied her up. They put her in the bedroom and tied the door shut.
Dawn was mentally strong, able to continue in her duty even after suffering an injury, although she still feared for her wellbeing. She didn't appreciate being mollycoddled. She was sensible in the face of danger, telling Andy that they needed back-up before they could think about helping anyone. (PROSE: Bay of the Dead)
Dawn had pale green eyes.
During the time of her infection, she was pale and sweating, with dark circles around her eyes which appeared glazed and dead. A stained red tea towel was wrapped around her injured hand and drool hung from her lips. She had a feral chalk-white face and hot, sour breath. (PROSE: Bay of the Dead)
