Ray Lambert

Ray Lambert shared a flat with Lauren Anderson. He was gay, something Lauren had taken into consideration when she'd decided to become flatmates with him: she hoped that it would lower the chance of romantic feelings coming between them in some fashion. After supporting her throughout the Cyberon incident in 2000, he was murdered and impersonated by the Zygon Torlakh in an effort to get to Lauren.

The Cyberon affair
When Lauren first showed Ray a picture of Tom Mordley in 2000, he fancied Tom. Shortly thereafter Tom and Ray met at a dinner that was initially planned between Lauren and Ray alone, and to which she invited Tom; after Lauren said she was tired and would like to go home, Tom proposed to stay with Ray and party for a while, briefly leading Lauren to wonder if she'd misread his signals and Tom was in fact romantically interested in Ray. However, he simply pumped Ray for information about Lauren, as well as monologuing to him about his theory on transhumanism.

Ray retained a bad feeling about Tom and the Cyberon drug he was advertising, especially after Lauren confided in him about her discovery of the fact that Tom was addicted to the substance himself. After Lauren filched a syringe of Cyberon from Tom's supply, Ray found it in her coat as he was doing the washing, and briefly believed that Lauren was an addict herself; observing the substance, he discovered it glowed in the presence of humans and could move on its own. He later shared his fear of the substance with Lauren, and they observed something even more frightening: the substance briefly creating a human face to stare back at them.

With Lauren driving off to Tom's house to confront him, he was baffled when, the next morning, Lauren seemed to be back together with Tom. However, she was under the influence of a dose of Cyberon Tom had forcibly injected into her, and she ultimately recovered her sanity and stabbed Tom, releasing them both from the Cyberon's influence for good.

Around a week after the events at Tom's house, Louise Bayliss visited Lauren and Ray in their flat, to inform her that Tom had died. After things got back to normal, Ray was "supportive" to Lauren throughout her psychological recovery from the traumatic events in which she had been involved. (PROSE: The Last Dose)

He accompanied Lauren to Tom's funeral. (PROSE: Silver-Tongued Liars)

Death
During the time Lauren was working in St Kitts Hospital, he was murdered and impersonated by Torlakh. (HOMEVID: Zygon: When Being You Just Isn't Enough)

Behind the scenes
Prior to appearing in Zygon: When Being You Just Isn't Enough, David Roecliffe's Ray had made his debut in the 2000 BBV direct-to-video production Cyberon, which also featured the debut of Lauren Anderson. Though having evolved out of a project initially planned to star the Cybermen, the finished movie had no legal ties to the Doctor Who universe, having replaced the Cybermen with a new species, the Cyberons. For this reason, it is not covered by this Wiki, which instead considers Zygon to be the character's DWU debut.

Arcbeatle Press later included a prose retelling of Cyberon in their anthology of the same name, which consciously retrofitted the movie's narrative into "in the Doctor Who world" by involving other pre-existing DWU concepts under licence from their creators. As a result, the character's second appearance as far as this Wiki is concerned postdates his first.
