A drone smashes into an uninhabited part of Atlantis, and when Rodney runs a diagnostic on it, his laptop is shut down by Replicator nanites. An accident during a sparring session with Ronon leaves Sheppard with a head wound, but by the time he reports to Dr. Keller, it’s healed – and the doctor seems to have no answer as to why. Ronon, Sheppard, Teyla and Rodney meet, admitting that they each have noticed something “off” about their surroundings. As they investigate their suspicions, Keller, Major Lorne and apparently everyone else in the city turns against them – everyone except the miraculously revived Elizabeth Weir. But even Weir seems to be as in the dark as they are. Eventually, Keller explains that the four suspicious crew members, plus Weir, are organic facsimiles of the original human beings, grown by the Replicators to try to learn how human beings descend. Furthermore, these aren’t Oberoth’s Replicators, but a splinter group; Oberoth’s Replicators are busy wiping out every human-inhabited world in the Pegasus Galaxy in an effort to starve the Wraith of potential food sources. When Oberoth’s Replicators do find them, though, Weir may have to sacrifice her life again – the original Weir having been killed months ago – so her comrades can escape.
