Synopsis by Hal Erickson
The SG-1 team is convinced that their comrade Daniel Jackson (Michael Shanks) was burned to death during an escape from the planet Oannes. In truth, Jackson is still alive and a captive of the amphibious humanoid Nem (Gerald Plunkett). Playing for time, Jackson agrees to help Nem locate his partner Omorca, who lived on earth during the Babylonian era. As Jackson and Nem discover that they have more in common than might be suspected, Jackson's earthbound team members, who are now not so certain that Daniel is dead, undergo hypnosis in hopes of retracing the events leading up to their cohort's "demise."
