Bunty Hamilton

Bunty Hamilton was a chef at a motel in 1979. She was engaged to a Kaftakkrofakian criminal, Cecil, who had planned to infect all the guests at the motel with an alien slime that would turn them into zombies. When the Doctor persuaded Cecil to give him the antidote, he was taken back to his homeworld, where he was tried and imprisoned for his crimes. Bunty left him, and was forced to live on the planet instead of Earth. (DWS: Zombie Motel)
