Katarina

Katarina – a typical Trojan name, I’m sure you’ll find – travelled with The First Doctor after Vicki decided to stay behind. She didn’t speak his language, could not grasp the rudimentary of mechanics of doorknobs or see the danger in lighting a fire in the middle of the TARDIS, but ultimately proved herself brave by sacrificing herself to save The Doc in The Daleks’ Master Plan.
