O'Neill uses the Ancients knowledge to lead SG-1 to a distant planet that is an Ancients outpost. He takes a power supply and leads them back to Earth again, to a similar outpost in Antarctica. With help from Hammond and the Prometheus, Jack repels Anubis' attack, destroying him and his forces. SG-1 are forced to put Jack into a stasis chamber, with no idea how to remove the Ancients' knowledge and save him.
