Bunty Hamilton

Bunty Hamilton was a chef at a motel in 1979. She was engaged to Cecil, a Kaftakkrofakian criminal, who planned to infect all the guests at the motel with an alien slime to turn them into zombies. When the Tenth 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)
