It was a family affair in the second series of JJ Abrams' wonderfully inventive Alias, as super secret agent Sydney Bristow (Jennifer Garner) came face-to-face with the mother of all super secret agents--her own mother, Irina Derevko (Lena Olin), a former KGB agent, presumed dead, and more dangerous than ever. After shooting poor Syd, Irina later shows up at the doorstep of the CIA, offering to turn herself in and work for the good guys. But can she be trusted?
