Emily Boyes - Dennison Emily Boyes - Dennison was the daughter of Professor Boyes - Dennison , the man who designed and created the three ships , " Cygnus " , " Lynx " and " Draco " , which were flown to the Moon in 1878 . Despite typical Victorian standards , Emily was a very strong - willed woman and a proto - feminist , having been treated more as an assistant than a daughter by her father ever since her mother ' s death some years ago . The only female on the expedition , she wore trousers as skirts were impractical due to the weightlessness experienced outside the atmosphere . During the trip to the Moon , she and Captain Richard Haliwell engaged in an argument about some of her views , which prompted her to storm off during a dinner , although they calmed down and maintained a civil discourse most of the time . She took a camera with her to take a few pictures of the new environment when they discovered a mysterious park on the Moon . When the expedition discovered the Fifth Doctor and Vislor Turlough while searching for the missing Sub - Lieutenant Granby , Emily spoke up in their defence against the initial accusation that they were spies , noting that spies wouldn ' t have been so casual about introducing themselves . When the search party was attacked by large aliens resembling overgrown spiders , Emily was forced to abandon her camera during their escape . Although they were able to return to the camp , she was subsequently taken captive with Captain Richard Haliwell to the Citadel , where they were kept prisoner by the Warden . She and Haliwell were forced to perform in tests , concerning their strength and stamina . They were given tests including running , climbing and swimming , and left in the same room between tests , prompting them to engage in discussion and bond further as time went on . In a larger test , they were forced to pick weapons for them to fight . Emily picked a longbow and arrows . She also picked a dagger just in case . Inside a vast room , which was more of an artificial forest , they were forced to fight all manner of creatures . Their last enemy was a Hydra , which managed to stick one of its horns through her body , just below her rib cage . When back at their prison cell , Haliwell treated her with an interesting solution , which repaired the skin rapidly and ceased the pain . When they were subsequently pitted against a robotic hunter , the two were saved when the expedition were able to take control of two of the warden ' s robotic saucers , the Doctor and Turlough piloting them into the dome where Haliwell and Emily were being tested . After escaping the Citadel following the Warden ' s death , she was keen to ride one of the saucers , to Haliwell ' s worry . During the flight back to Earth , Halliwell proposed to Emily , but she asked him to consider if he would support her beliefs in equal rights for the genders as a whole rather than believing in her as an individual example . After the attack by the Vrall was narrowly averted by the Doctor and Turlough , Halliwell immediately proposed to Emily again after she was discovered alive , telling her that , while he did not yet share her views , he was willing to learn more from her , with Emily accepting the proposal .
