Biography

Born in Sheffield in 2028, she gained a first honours chemistry degree and went into engineering. She would later become a British cosmonaut on the Russian Federal Space Agency mission Project Midas, beating over twenty-five thousand other candidates, and in 2051 became the second British woman to have landed on the moon. She met the first woman, Adelaide Brooke, and the two developed mutual respect. Brooke asked Cain to join the Bowie Base One mission.

She flew up to the base in 2058 and worked there, studying the planet Mars with a team of humans. She was infected with a virus, known as The Flood, that changed her body form. With the other infected members, she tried to infect the remaining crew and escape to Earth, but failed, due to the actions of The Tenth Doctor. While infected she appeared to act as the leader of those infected by the virus, and was shown to have a voice powerful enough to crack the ice holding the main body of The Flood. She was blown up when Adelaide, her captain, took "Action Five" and destroyed the Base. (DW: The Waters of Mars)

Behind the scenes

• The Doctor's flashback to Maggie's obituary notes that she was from Grenoside, Sheffield, and was a chemistry graduate from the University of Sheffield; two things she shared with Helen Sharman, the first Briton in space. Like the other female member of the Flood, Steffi, she kept her eye colour. It seems the males had milky, blue eyes while females kept their colour.
