First it looks unbelievable - Nikita has given change to leave with one condition - she can never contact noone inside. For six month it works then oneday George appears and says - Nikita has to kill Operations in order to have this freedom. So, it is her decision now but it becomes easier when he tells her that Operations is the man who killed her father and some hints why Nikita was recruited. So, Nikita makes an easy step to get back by contacting Michael - easy way in but it makes Madeline suspicious. Still, Nikita manages to find a way to continue her mission. But again Madeline is there in the right moment to stop her but they all are sure - there is someone inside helping. Nikita suspects it is Michael and Madeline thinks the same. But no matter of that, Nikita gets to Operation's office and threatens to kill him. Then Madeline comes up with story that Operations is Nikita's father and that is the only reason why she is still alive after all the things, why they tolerate her relationships. But was it true or Madeline made it up? We never know.
Exciting episode with so many new questions.
