Mentioned in "Remnants"
Donovan is a male of the Tau'ri and a member of the Atlantis expedition. In 2008, Donovan and his team along with Dr. Radek Zelenka visited M2J. While they were on the planet, back on Atlantis, the Sekkari AI took the form of Zelenka to ensure Dr. Rodney McKay would find the seed carrier on the ocean floor. The AI's explanation for Zelenka's early return was that three members of Donovan's team suffered a severe allergic reaction to whatever was in the food on M2J. (SGA: "Remnants")
