Replicators are raining down on Orilla, last Asgard colony. While Carter realises her ideal of a life in Montana with lover Pete has been engineered by Fifth, who claims to love her, Thor interfaces O'Neill with the 'Daniel Jackson' ship's computer enabling him to build an Ancient weapon which defeats the Replicators. Fifth escapes, leaving Carter behind. Brigadier General O'Neill takes command of the SGC, promoting Carter to Lt. Colonel. A new humanoid Replicator achieves consciousness and joins Fifth. It's a duplicate of Carter.
