Alias: A Dark Turn

Sydney is informed of unauthorized meetings Vaughn has taken with KGB and she becomes suspicious of him after he is put under investigation. She confronts him and he reveals he has been investigating Irina on his own time for his peace of mind. Francine's "clone" sleeps with Will, hypnotizing him to reveal secret satellite codes. Jack forms an uneasy alliance with Irina to see if they can bait and capture Sloane. Irina is released from her cell and Jack secretly deactivates her tracking device to prevent any possible discovery. Irina is taken away by Sark who uses the stolen codes from Will to scramble the CIA's tracking signals. The CIA discovers that she also stole the Rambaldi manuscript which she delivers straight to Sloane, seeming to have been in cahoots all along.
