“Martha Smith-Jones, also called Dr Martha Jones and often referred to as Martha Jones, was a British physician. She met the Tenth Doctor while in residency at Royal Hope Hospital in London when the hospital was transported to the Moon by the Judoon troops, after which she began travelling with the Time Lord… Unlike other companions, she not only became infatuated with the Doctor but also declared her feelings to him. She decided to stop traveling with him as he could not return her affection, but continued to have a number of adventures, both with and without him, thanks to her work with UNIT and Torchwood.” – Doctor Who Wiki
