An astrophysicist with a photographic memory, Zoe joined the Doctor and Jamie after helping them defeat the Cyber-invasion of the Space Station W3. Clever and logical but with a big heart, Zoe was more than a match for the Doctor. Her intelligence brought her to the attention of the Krotons, Ice Warriors and the Cybermen, and she was the first to see through the lies of the Land of Fiction. At the Doctor's trial after the war games, the Time Lords returned her to her old life with memories of only her first adventure with the Doctor remaining.
