*As O'Neill prepares for the dangerous deprogramming, Carter realizes the flaw in the Zatarc technology. The device can misread emotions, interpretting omissions as lies, and giving a false reading. O'Neill and Carter are retested, admitting feelings they had previously concealed, and they are cleared as Zatarcs. It is not until the real Zatarc attempts to assassinate the Earth and Tok'ra leaders that his identity is discovered. It was Martouf who was the unknowing victim of Zatarc programming, and who dies as he attempts to carry out his suicide mission.
