The controversial final episode, in which Thomas Veil learns he's not Thomas Veil at all.Following up on Robman's secret information, Tom finds two valuable clues: the original photo of Hidden Agenda with four U.S. Senators as victims rather than four South American rebels, and a key to the safehouse inhabited by the agent who gathered the data for Robman -- a man coded Gemini. Settling comfortably into Gemini's concealed Virginia home, Tom makes contact with the one senator who would appear to profit from the deaths of the other four, but before they can effectively exchange information he, too, is erased. When Robman also disappears Tom uses Gemini's pass into secret F.B.I. files to determine who arranged his transfer and uncovers The F.B.I.'s number 2 man -- Barton. Tricking Barton into an unwelcome rendez-vous Tom catches him in the act of destroying all the Gemini files. At the very edge of enraged insanity Tom brutally forces the truth out of Barton -- who takes cyanide pills, but not before letting Tom know that the man he's searching for is actually himself! As Barton dies Tom looks at the Gemini video that's playing and sees himself being programmed to believe he's one Thomas Veil of Evanston, IL with a beautiful wife named Alyson and a best friend named Larry Levy. The final episode ends on Tom's devastated face as he hears himself repeat by rote: "My name is Thomas Veil....."
A flawed episode with too many loose ends (why didn't Robman recognize Tom?), an improbable solution (five cloned senators?) and far too many voice overs, Gemini remains surprizingly good -- regardless of whether Tom is really the re-programmed Gemini or whether he was just being elaborately fooled once again. In some ways either theory would work, which left the planned second season wide open.
For Bruce Greenwood fans the final scene is one of his most memorable, as brimming with frustrated anger Thomas Veil rips into the arrogant Barton only to crumble at the overwhelming possibility he's not Thomas Veil at all.
