Rosie Marcel "fought very hard" for Jac Naylor not to die in Holby City's finale.
The BBC soap ended last night after 23 years on screen and in tragic scenes at the end of the episode, Jac finally lost her battle with her inoperable brain tumour and her organs were donated to other patients.
Rosie has now admitted she was desperate for Jac not to pass away in the show, and joked she was a "nightmare" as she battled with the show's bosses and writers about how the storyline would end.
