Allison Williams Allison Williams was Professor Rachel Jensen ' s assistant during the Shoreditch Incident in the relevant area of London in November 1963 . She was the girlfriend and eventual fiancée of Julian St Stephen . Biography . Allison was born in the Herefordshire village of Lower Burford to a farm ing couple . Her birth was very difficult for her mother , resulting in her being unable to have further children . Allison had a poor relationship with her father . She believed that her father always resented the fact that she was not a boy and that he always cared more about his animals than his family . When she was 14 , she was given flower s by Jack Maddocks during the Easter holidays . Allison was not fond of Lower Burford , describing it as " a hillbilly hellhole " in 1965 . She left home to attend the University of Cambridge in 1956 , at a young age , and did not return until her father was taken ill nine years later . She had deliberately left young in order to force her father to ask why she ' d left , but he never did . ( AUDIO : " The Forgotten Village " ) At Cambridge , she was the top of her class and noted as someone to watch by the government . ( AUDIO : " Changing of the Guard " ) Rachel had been one of her lecturer s at Cambridge . Her classmates included Anne Travers and Ruth Ingram . ( PROSE : " The Scales of Injustice " ) In November 1963 , she appeared on site with Professor Jensen and witnessed a Dalek kill several soldiers attached to the ICMG under the command of Group Captain Ian Gilmore . It was at 76 Totter ' s Lane that she met the Seventh Doctor and Ace , whom she later assisted in defeating both the Renegade and Imperial Dalek factions who were searching for the Hand of Omega . ( TV : " Remembrance of the Daleks " ) She was sent by Toby Kinsella to infiltrate an anti - nuclear commune after the assassination of Stephen Mulryne . She met with Martin Regan for membership . She was hypnotised by Martin to kill ' John Rutherford ' , Gilmore and the herself . Fortunately , because she was told to kill John Rutherford , her controlled mind was unable to complete her instructions as she recognised ' Rutherford ' as the Doctor , allowing him to break her programming . She then proved vital in helping the Doctor and Gilmore identify another key player in the conspiracy . ( AUDIO : " " ) While at Cambridge , she obtained the highest first class honours in her year . ( AUDIO : " Artificial Intelligence " ) She completed her degree and obtained her doctorate in 1964 . ( AUDIO : " Threshold " ) She and Julian had started dating in 1961 but , after three years , she was becoming concerned as to what he wanted from their relationship . When the artificially intelligent Sentient Engine Generator 2 computer , also known as Sen - Gen , had tapped into her mind and amplified her subconscious fears , she went to Julian ' s flat and cut all of his clothes with the exception of his tennis outfit into shreds and wrote , " Why don ' t you love me enough ? " in Pastel Pink lipstick across his wardrobe . Under Sen - Gen ' s influence , she later threatened to shoot Julian . However , he told her that she could resist Sen - Gen as she was the strongest willed person that he knew . He explained that he did not take their relationship any further as he did not want to hold her back . In order to reaffirm his love for her , he proposed to her . She accepted and put the gun down . Julian later reflected that they would have to come up with a story to tell not only Allison ' s mother , whose presence he claimed was enough to trigger a psychotic episode , but their children in years to come . ( AUDIO : " Artificial Intelligence " ) To Alison ' s dismay , Julian turned out to be part of a military coup against PM Harold Wilson and he hadn ' t really loved her : it had all been part of the coup plot , with him able to resist Sen - Gen as he knew he was lying . To save the Prime Minister , she had to shoot him dead . ( AUDIO : " State of Emergency " ) For months after , she surpressed any problems and threw herself into her work . Rachel Jensen noted that she had been acting different since then but Alison waved it off . ( AUDIO : " Manhunt " ) In 1965 , Gilmore described Allison as being " as icy as a holiday in Barbados . " ( AUDIO : " The Fifth Citadel " ) On another occasion , he described her as " a game girl " . ( AUDIO : " Changing of the Guard " ) Prior to her trip to Amsterdam in 1965 , Allison had never previously flown . ( AUDIO : " Peshka " ) Her father died in 1965 . ( AUDIO : " The Forgotten Village " ) In 1965 , Rachel joked that Allison drank so much tea that she kept the East India Company in business . ( AUDIO : " Unto the Breach " ) She was brainwashed by Templeton to think that he was Toby and another Captain was Gilmore . ( AUDIO : " New Horizons " ) Professor Williams led the scientific team which investigated the Cyberman ship in Antarctica in December 1986 . ( PROSE : " The Power of the Daleks " )
