A teenage boy shows up at the SGC claiming to be Jack O'Neill. He recalls a dream in which an Asgard was studying him. They determine that they must find this Asgard to fix what has been done to Jack.

SGC security stop a teenager who has gained access to the facilities by using Jack O'Neill's key card. When asked how he got hold of the card, his answer is simple: he claims to be Jack O'Neill. Although incredulous at first, the knowledge the young man displays about their operation eventually convinces them that they are in fact dealing with Jack. All he can remember is being in a dream-like state and being taken by the Asgard. Medical tests reveal that his body is changing at the cellular level and Jacob Carter recommends that Jack be put into stasis until they can figure out what exactly has happened to him. Jack's solution is to leave the SGC without permission. Soon after he leaves, Dr. Carter and Jacob figure just who they are really dealing with.—garykmcd

SGC is stunned when a cocky teen knave, stopped by security, claims to be the only Jack O'Neil, who is on leave but can't be found home, using is key card and knowing more than anyone else could. Daniel and Sam get convinced it's their colonel, but amnesiac and referring to an alien abduction of an Asgard type, actually fitting many civilian reports with a specific detail. Medical tests from military staff and Jacob's Tok'ra team show his body is decaying, due to a flaw in DNA manipulation, the teen proves genuinely knavish while competent as space pilots instructor. They call upon Tor, who concludes it's forbidden Asgard cloning, and set a trap for perpetrator Loki, recuperating adult Jack, while determining the duplicate's fate seems the moral nightmare.—KGF Vissers
