Characters of Casualty - Zoe Hanna

Zoe Hanna is played by Sunetra Sarker and first appeared on 29 December 2007. She is the Clinical Lead in the Emergency Department.

She had an affair with Orthopaedic Consultant Sean Anderson, unaware he is the husband of her colleague and friend, nurse Jessica Harrison. In series 22 episode 29, she is promoted within the department over colleague Maggie Coldwell. When Maggie appears at a tribunal for negligence, hospital manager Marilyn Fox asks Zoe to lie in court, condemning Maggie. She blackmails Zoe, threatening to expose her affair with Sean. Zoe disregards her threat, clears Maggie's name, and admits to the affair herself. Zoe is dismayed when she discovered she cannot have children. She becomes close to Abby, a patient of hers who is being abused by her husband and his father. She takes in Abby and her daughter Sharice, and when Abby and her husband are both killed in a fight, begins fostering Sharice. She takes steps towards adopting her, however comes to realise that she is struggling to balance her work and childcare, and allows Sharice to live with her maternal grandparents. Another major storyline which reached its peak in the episode 'Sunset Syndrome' involved Zoe lying in order to save Nick Jordan's life against his will. Much remains unsaid in this relationship as he originally did not appreciate her actions stating that he had given permission to undergo surgery, with him later assuming that Zoe was pregnant, prompting her to begin failed cycles of fertility treatments. He never realised this, and broke up with her upon discovering she was not pregnant, which he had merely assumed.

Yvonne Rippon was stabbed during the Holby riots, which resulted in Nick Jordan Clinical Lead taking extended leave to support his partner. Director of Surgery Henrik Hanssen promoted Zoe to Clinical Lead.
