Tina Seabrook is a fictional character from the BBC medical drama Casualty, played by Claire Goose. She made her first appearance during the twelfth series episode "Give My Love to Esme", which was broadcast on 11 September 1997. Tina was introduced as a staff nurse in Holby City Hospital's emergency department. Goose was tempted to give up acting when she attended the audition for the part. It marked her first major television role. Goose spent a day at a real-life hospital while researching her character's occupation.
Tina was portrayed as being feisty, bubbly, confident, and a bit naive. A notable storyline arc for the character was her rape at the hands of a patient's husband. Producers hoped the plot would raise awareness of the dangers nurses face at work, as well as increase ratings. Goose wanted Tina to be given a love interest to show her continuing recovery from the assault, and Tina begins a relationship with senior house officer Sean Maddox (Gerald Kyd). He later has an affair with Tina's best friend Chloe Hill (Jan Anderson), which results in her pregnancy.
Goose chose to leave her role in 1999, and she made her final appearance in the fourteenth series episode "Being There – Part 2" on 25 March 2000. Tina leaves Holby to reunite with Sean in Australia. For her portrayal of Tina, Goose earned a nomination for Best Newcomer at the National Television Awards. Her introduction also led to improved ratings for the show. Goose was praised for her performance during Tina's rape storyline, but her exit was branded "nonsense" by a television critic.
