Season 3, Episode 11 - "Full Disclosure"
11 January, 2004
In this episode, Sydney finally learns the shocking truth about her missing two years from an unlikely source: FBI Special Officer Kendall, who whisks her away and from the privacy of an airborne 757 jet clears the air over her disappearance. According to Kendall: Sydney was captured by the Covenant after her fight with Francie/Allison and held captive in Russia for over a year and brainwashed to become an assassin. But Syndey only pretended to be brainwashed and contacted Kendall who became her contact and handler, thus giving him information about the Covenant and of their quest for Rimbaldi artifacts as well. Sydney also staged the murder of Lazarey, and then deliberately had her memory erased to prevent the Covenant from knowing about secrets she learned about Rimbaldi's findings.
