During the first test flight of a Puddle Jumper that Dr. Zelenka has repaired, the small ship abruptly crashes and sinks into Atlantis's ocean with Dr. McKay and the pilot, Griffin, on board.

Above an isolated moon, Sheppard's team discovers two battered life pods in decaying orbits. They bring them to Atlantis, where Dr. McKay opens the first pod. An aged, unconscious woman lies within, near death. When Dr. Weir approaches for a closer look, an energy beam lances out of the pod and strikes her. Weir collapses.
