FRAGILE BALANCE

Story line: Jack O'Neill disappears from his bedroom - and in his place is Young Jack, a teenage boy who claims to be the real Colonel O'Neill, only 30 years younger.

[Young Jack] A cute teenage boy, 18 to play 14 to 18, there's something familiar about him; he closely resembles a teenage version of Colonel Jack O'Neill (Richard Dean Anderson). Gruff, irritable, sardonic, and testy, a young man with a big attitude. Young Jack claims that in fact he is Colonel O'Neill - that he woke up this morning looking thiry years younger and expects Stargate's team to do something about it. Profoundly annoyed to be treated dismissively simply because he looks like a kid. Young Jack has the DNA of Jack O'Neill and the irritating assertiveness to go with it. Intent on reclaiming his status as a veteran warrior, Young Jack succeeds largely in amusing the Stargate team - until they learn that he is dying. In fact, Young Jack is a clone of the real O'Neill, who has been abducted by aliens from Asgard. With O'Neill's memories downloaded into his mind, Young Jack has been born ready to kick butt and take names - if he can live long enough for his zits to clear up ... LEAD (2)

New information:

Apparently a teenage boy turns up at the SGC, in Jack's clothes, claiming to be Jack O'Neill. Nobody of course recognizes him, not even the once-again human Daniel (who doesn't remember everything). Also, the SGC team interviews alien abductees (the kind Mulder was always running across in X-Files). Jack Jr is his usual sarcastic self. And it seems that Jack Jr's lifespan is limited (as stated above).
