It's On! Alex and Nikita Face Off in the Season 2 Premiere (PHOTOS)

With help from an unlikely ally, Nikita (Maggie Q) and Michael (Shane West) plot to take down Division and Oversight with the contents of the black box. Amanda (Melinda Clarke) is now in charge of Division, but Oversight has assigned one of their own, a new agent named Sean (guest star Dillon Casey), to keep an eye on her. Amanda enlists Alex’s (Lyndsy Fonseca) help for her first mission — to get back the black box from Nikita. Alex refuses until Amanda tells her she will help her find the man who killed Alex's father.
