Julian St Stephen Julian St . Stephen was a researcher who worked as a consultant to the Ministry of Defence in 1964 . He was the boyfriend and eventual fiancé of Dr Allison Williams , as part of a plot by Army Intelligence . He was well versed in physics and psychology . In university , Julian joined the Young Fabians but flirted with the idea of joining the Socialist Review Group . ( AUDIO : " Artificial Intelligence " ) He became more right wing after leaving . ( AUDIO : " State of Emergency " ) Because of his old associations , the MoD was initially somewhat reluctant to hire him as it was feared that he was a Trotskyite . ( AUDIO : " Artificial Intelligence " ) However , while the MoD continued to claim they were reluctant , Army Intelligence did recruit him as a spy . ( AUDIO : " State of Emergency " ) He served several months in the Greek Islands as part of his national service . ( AUDIO : " Artificial Intelligence " ) In 1961 , he was asked to spy on the new Intrusion Countermeasures Group . As part of his cover , he dated Allison Williams , who wanted more from the relationship than he was willing to commit . ( AUDIO : " State of Emergency " , " Artificial Intelligence " ) In 1963 , she wrote him a letter after the Shoreditch Incident . ( PROSE : " Remembrance of the Daleks " ) After Dr Archibald Hemmings committed suicide by jumping under a train in 1964 , Julian assisted Allison and her Intrusion Countermeasures Group colleagues Group Captain Ian Gilmore and Professor Rachel Jensen in investigating the Sen - Gen Facility , where Hemmings had been working until his death . Due in part to his anti - military views , he did not have a particularly high opinion of Gilmore , remarking to Allison that the Group Captain was so buttoned up that he was surprised that he could fit his head through his collar . Similarly , Gilmore was not fond of Julian on either a personal or a professional level . He was contemptuous of the science of psychology , claiming that it involved nothing more than getting people to talk about their feelings and their mothers at length . He told Julian that he had several elderly aunts that spent most of their time doing the same thing . He and Allison 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 ( Sen - Gen ) had tapped into her mind and amplified her subconscious fears , Allison went to his 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 him . However , Julian 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 . He was able to claim that he had no doubts because Sen - Gen was unable to effect him ( AUDIO : " Artificial Intelligence " ) but the reason he had no doubts was that he " knew " he was lying , in order to get Allison to put the gun down . ( AUDIO : " State of Emergency " ) Impressed by his initiative during the Sen - Gen incident , Sir Toby Kinsella offered Julian the opportunity to be re - assigned to General Peters ' staff in order to assist with a special project of the utmost secrecy . ( AUDIO : " Artificial Intelligence " ) This turned out to be a planned coup : Peters and his allies were sure the Labour Party were going to win the next election and feared Harold Wilson was a communist . Julian willingly joined up and worked on setting up a teleportation device to stage alien attacks . Sir Toby was working against the coup and arranged for Allison to discover what Julian was doing . She initially believed he was being conned but he revealed that he was not only aware , he hadn ' t really loved her . In order to stop him killing the Prime Minister , Allison shot him dead .
