*Fifth probes Carter's mind, and offers to help SG-1 to escape if they will take him with them. He makes the necessary alterations to the time dilation device, leaving Carter to set the timer. They allow enough time for each of them to return to the ship before activation, however, O'Neill signals Carter to alter the timer, leaving insufficient time for Fifth to join the team. To protect the galaxy from the Replicators, SG-1 is forced to betray Fifth and to use his humanity against him, trapping him within the time dilation bubble with the others as SG-1 makes their escape.
