*The SG-1 team returns from P9X-391 with an unusual alien artifact. Shortly after their return, Jonas sees what appears to be an enormous flying insect-like creature in the gateroom, capable of passing through solid matter. Despite a full search of the base, no one else sees the creature, and Jonas submits to medical tests, but is found to be in perfect health. Carter and Jonas study the artifact, and ascertain that it is emitting energy, but are unable to determine its purpose. However, when Teal'c and Jonas both see another of the creatures, it seems that the alien device may be responsible.
