Without introducing himself , the Doctor merely took off his tie and said , " Like so , see ? " , before walking off . Unbeknownst to Martha at the time , he was demonstrating the nature of time travel . She met him again at the hospital , where he was posing as a patient named John Smith , not realising that the man she saw earlier was a future version of him ; she also listened to his heartbeat , discovering that he had two hearts , but stayed quiet about it . Later that same day the hospital was transported to the Moon by the Judoon . Calm while those around her panicked , Martha worked with the Doctor to track down the Plasmavore , " Florence Finnegan " , for whom the Judoon were searching . During this encounter , the Doctor was quickly impressed with Martha ' s reasoning and intelligence , such as when she deduced that opening the windows wouldn ' t result in the air being sucked out ; it would ' ve happened already anyway if it were going to happen at all as the windows weren ' t airtight . Despite listening to his heartbeat , however , Martha was sceptical about him being an alien , until the Judoon ' s scanners confirmed that he wasn ' t human . As the oxygen in the hospital ran out , Martha gave her last breaths to resuscitate the clinically - dead Doctor , who had thwarted Florence ' s plan . The Judoon returned the hospital to Earth .

The Doctor also constructed three perception filters using TARDIS key s in order to avoid detection , the three of them declared Earth ' s most wanted . The Master , who had been manipulating Martha ' s family since she became a full - time companion , had Francine , Clive , and Tish arrested , although Leo escaped , Martha calling and warning him before the Master could find him .

( TV : " Last of the Time Lords " ) She was later engaged to Tom , but eventually married Mickey Smith instead . ( TV : " The End of Time " ) Her time walking the Earth gave rise to a more soldier - like and less naive side of Martha .

Despite their strained relationship , she remained loyal to the Doctor , and indeed took many of his teachings to heart . For instance , despite her work at UNIT , she very rarely carried a gun .

( TV : " Last of the Time Lords " ) She was shown to fluently speak German . ( TV : " Journey ' s End " ) She also proved handy with a gun . ( TV : " The Family of Blood " , " The End of Time " ) Of course , her medical skills were her most developed , especially after the experience she gained with aliens and other unusual medical situations , finding her working with organisations such as UNIT and Torchwood Three . ( TV : " The Doctor ' s Daughter " , " The Sontaran Stratagem " , " Reset " , " A Day in the Death " ) Behind the scenes . " Torchwood " and " SJA " .

Although there were unconfirmed rumours that Agyeman was seen at a " Torchwood " filming location , she did not appear in the " Children of Earth " miniseries ; she was referenced in dialogue as still being with UNIT . Her subsequent appearance at the end of TV : " The End of Time " again fueled speculation of a possible future " Torchwood " appearance , which did not come about in the revived " Torchwood " . Russell T Davies originally intended for Martha to appear in " Torchwood : Children of Earth " miniseries and " Enemy of the Bane " , the series 2 finale of " The Sarah Jane Adventures " . Freema Agyeman ' s casting in the ITV series " Law & Order : UK " resulted initially in her " Torchwood " appearance ( along with an appearance by Mickey Smith ) being reduced to a cameo , and then eliminated completely . Later , her schedule also precluded Agyeman from appearing in " Sarah Jane " , resulting in Nicholas Courtney returning as the Brigadier instead . ( REF : " " ) Had she appeared in these two productions , she would have been the first major character to play an important role in " Doctor Who " and both of its direct spin - offs ( even including the Doctor , who to date has not appeared in " Torchwood " ) .
