Deeper than before
28 September 2009 | by See all my reviews

After preventing the literal explosion of an acclaimed humanitarian in Brazil, Sydney gets her new mission: to accompany a German chemist from Berlin to the United States, so that he can reveal secrets of his research to SD-6. But the CIA is also interested in that scientist, and, benefitting from the fact that SD-6's only photograph of him is 25 years old, they have Sydney surrendering him to them instead and they give her a CIA agent who will impersonate the scientist for SD-6. Trouble ensues when Sloane starts asking questions that the doppelganger can't answer....This episode digs deeper than the previous ones into the complexities of the spy game: should Sydney reveal to Dixon that she's a double agent? On the one hand, that could put both in serious danger. On the other, if she had done it, the shocking event that happens at the end of this episode would have been avoided. The triple intercutting between different scenes (and times) in the middle is a fantastic piece of direction, and even the subplots are more suspenseful than before, with Will meeting the non-existent (?) "Kate Jones", and Sydney learning that FBI might have been investigating her father's actions in the past. The best episode since the Pilot. *** out of 4.
