Template:Stargate character Lieutenant Laura Cadman, played by Jamie Ray Newman, is a character on the science fiction television show Stargate Atlantis. She is in her mid-20s, judging by her appearance and rank. She first appeared in Episode 204, "Duet" and she is returned in Episode 213, "Critical Mass" to become a more permanent member of Colonel John Sheppard's SG team.
In "Duet", she was offworld with a team investigating a Wraith culling when a Wraith Dart attacked and "scooped up" herself and Dr. Rodney McKay. The team shot down the Dart, but it crashed and was badly damaged. Dr. Radek Zelenka accessed the dematerializing machine in the Dart and found two lifesigns, but could only rematerialize one with the power in the Dart's damaged energy cell. Col. Sheppard picked one lifesign at random and Dr. Zelenka rematerialized it. It turned out to be Dr. McKay, who promptly collapsed.
Back in Atlantis, Dr. McKay woke up in the infirmary only to start hearing Cadman's voice in his head. Somehow, Cadman's consciousness had been transferred into McKay, while her body was still dematerialized in the Dart. She could see and hear what he could, and could talk to him, but only McKay could hear her. McKay thus seemed to be crazy as he started talking to "himself".
Cadman started distracting McKay, talking to him while he was trying to work. Eventually, Cadman proved able to control McKay's body if he let her. She used this ability when McKay fell asleep, asking Dr. Carson Beckett to accompany McKay on a date and going for a run before heading to her room ("Your mattress sucks"). McKay was angered that his body had been used without permission. Cadman also helped McKay out on his date (in an unusual sort of way).
Soon after, however, McKay had a seizure and fainted. It turned out that their constant fighting over control was having a negative effect on McKay's vital functions. One of them had to let go completely, resulting in death. Cadman volunteered, but McKay, in a flash of inspiration, figured out how to use one of the Stargate's control crystals to separate the two. Soon Cadman was back in her own body.
Lt. Cadman enjoys running in her spare time and was a track star in high school. She was also the owner of a dog, whose picture we glimpse on her nightstand in "Duet." She came to Atlantis on the Daedalus.
She was scheduled to leave in the Daedalus, but she asked Col. Sheppard to stay for a bit more. She is an expert in explosives, or, as she puts it to McKay, in high temperature and energetic materials technology ("Critical Mass").
It appears that Dr. Beckett is pursuing the relationship that she struck up with him during the situation in "Duet" ("Epiphany").
