Sergeant Ketterings was among the personnel assigned to guard duty at Cheyenne Mountain after the stargate was deactivated following the first Abydos mission. When Apophis unexpectedly opened the Earth stargate, he captured Ketterings and took her back to Chulak as a possible host. However, Ketterings was later rejected as a host for his queen, and she was killed by Apophis's ribbon device.
