Examining crystalline formations on an unexplored world, O’Neill is knocked out cold by a burst of energy – and then a duplicate of him appears to accompany SG-1 back to Earth. The duplicate goes through O’Neill’s personal effects, finding a picture of what he believes is O’Neill’s home, and then goes there, and a disturbing encounter with O’Neill’s ex-wife ensues. It quickly becomes apparent that this duplicate knows nothing of what happened to O’Neill’s son Charlie, who died after accidentally shooting himself with O’Neill’s gun. When the real O’Neill recovers and comes through the stargate, he’s treated as a duplicate until he can prove who he really is – but before the team can figure out what has happened, the ersatz O’Neill, actually a being composed of energy, has begun to lose his human form, endangering everyone around him.
