Doctor Dumais was a Tau'ri scientist and Atlantis expedition member. During the first year, she was inspecting the storm-damaged parts of the city and was in the same category with Dr. Rodney McKay, Dr. Radek Zelenka and Lt. Aiden Ford. She explored an Ancient lab, which Dr. Johnson and Dr. Wagner discovered. Ford asked why the virus became active precisely then, and she explained that the virus could lie dormant a long time and then 'wake up'. And just when she began to see shadows, she ran straight into Hays. A few seconds later, she died and became the third victim of the virus. (SGA: "Hot Zone")
