 Rambaldi s catastrophic endgame begins to fall into place as a giant red ball version of the Circumference/Mueller device is found floating over a large city in Russia, driving the citizens mad with violence. After a wounded Dixon reveals that Irina is alive, Sydney, Nadia, and Jack set off to find her. It turns out that Irina had been captured, and then duplicated using Project Helix, in order to give the impression that she was dead. Sydney and Nadia discover Irina being held inside a camp in Tikal, safely in the clutches of Elena s private army. Irina had apparently been working to counter Elena s organization, the Covenant, and actually PREVENT the Rambaldi endgame. Irina is taken to APO and tells them of a page she destroyed, a page that was key to Rambaldi s endgame. Under torture, she finally broke and recreated it for Elena. After a short respite, Sydney, Vaughn, Jack, Nadia, and Irina board a plane parachute down, towards Elena, Sloane, the Circumference....and destiny.
