In the second season premiere, Nikita & Michael plot to take down Division & Oversight & are prepared to use the contents of the black box to do so. Amanda is now running Division but Oversight has assigned one of their own, a new agent named Sean (recurring guest star DILLON CASEY -- The Vampire Diaries), to keep an eye on her. Amanda's first mission is to get back the black box from Nikita, & she enlists Alex's help to do so. Alex refuses until Amanda tells her she will help her find the man who killed Alex's father. Meanwhile, Nikita & Michael find help from an unlikely ally.
