Characters of Casualty
Sean Maddox, played by Gerald Kyd, made his debut appearance in the first episode of the thirteenth series, broadcast on 5 September 1998. Sean was initially billed as a "sexy junior doctor", who "is young and single and he enjoys flirting with patients and nurses alike." Sean later became a senior house officer. He formed a relationship with nurse Tina Seabrook (Claire Goose), but later had an affair with her best friend Chloe Hill (Jan Anderson), resulting in her pregnancy. Sean and Tina departed at the end of the fourteenth series. Kyd did not want to get "too comfortable" in his role and he also disliked playing the "heartthrob", as he felt it did not suit him. Kyd reprised his role in 2006 for the show's 20th anniversary and returned in episode five of the twenty-first series, which aired in October.
