*The search for the Goa'uld leads SG-1 to the Land of Light, a world struggling with a mysterious disease that causes primitive behavior in its victims. Carter is among the first of the SGC to contract the virus, which she passes onto Colonel O'Neill. O'Neill is locked up after striking Dr. Jackson and quickly degenerates in both appearance and mental capacity. Even though he doesn't have complete control over his impulses, he demands more sedative from Dr. Fraiser to ensure that he doesn't do any further harm. When Dr. Fraiser discovers a cure for the disease in a powerful antihistamine, Jack volunteers to be the first subject of the untested and possible lethal cure. With the cure a success, Colonel O'Neill delivers it to the people of the Land of Light in a gesture of good will and foundation of future trade.
