Vanessa Moretti Vanessa Moretti ( born 2359 ) was the 16 - year - old daughter of Salvatorio Moretti , who invented the GENIE s in the 24th century . Not knowing one was near her , she wished she could have lived " back then " . Hearing this , the GENIE transported her from 2375 to 2nd century Rome . The Tenth Doctor and Rose Tyler met her there in 120 AD . They brought her back to her home time before the GENIE was invented , telling her to convince her father never to create it . ( PROSE : " The Stone Rose " ) In Rome . When Vanessa first landed in Rome in 120 A . D . , the first person she happened to come across was a greedy man by the name of Balbus , who , upon realising she had sophisticated knowledge , accused her of being a runaway slave and claimed her as his own . Spreading rumours that she was a fortune teller , people came to her to find out about their futures . Unfortunately , Vanessa could not see the future and knew very little of astrology , and generally made the best guesses she could as to what would happen to the people who came to see her . Being as intelligent as she was , her guesses were normally very accurate , and she became well - known . Gnaeus Fabius Gracilis heard of her from a barkeep and sought her out to see if she could tell him anything about his missing son , Optatus . He offered Balbus a lot of money to speak to Vanessa . She began making random calculations trying to stall for time , and Rose quickly realised that Vanessa had no idea what to say to him . The Tenth Doctor recognised very advanced mathematics from the 24th century , and assumed she could actually see into the future . Eventually , Gnaeus haggled with Balbus , trying to buy Vanessa from him to bring her to his villa so she could investigate into Optatus ' whereabouts . Rose was thoroughly disgusted by the two men , haggling over a human being like she was an object . Upon being brought to the villa , Marcia Gracilis began telling Vanessa Optatus ' life story in hope of it helping her determine where he might be . Still not knowing what to say , Rose rescued her from the situation , saying she needed to meditate on the information . Vanessa couldn ' t figure out where Optatus was , and merely followed the Doctor ' s lead . When the Doctor found out about Ursus ' ability , he tried to find Rose ' s statue and he and Vanessa split up to try to find her . The Doctor did not see her for days afterwards . They met up again and followed Ursus ' wagon , finding Rose ' s statue in it and using the formula to reverse the effect . She , the Doctor , and Rose found Ursus in a decrepit shrine preparing to sacrifice a lamb to the god ess Minerva . Rose tried to stop him , but failed . Vanessa was terrified when Minerva absorbed the entire slain lamb . Ursus tried to attack her and she dodged him , causing him to fall upon his own dagger , and Minerva absorbed him too . The Doctor wished that Minerva reveal its true from and Vanessa recognised her father ' s invention . It was at this point that the Doctor came to the conclusion that she was from the future , and helped her back to her own time . The Doctor warned her that while her father ' s laboratory and research would be destroyed in the future , his mind would still exist and she must keep him from trying to make another GENIE . However , Vanessa did not remember this warning and after the destruction of the laboratory began contemplating asking her father to make her another GENIE . ( PROSE : " The Stone Rose " )
