I've commented several times about how there is little nuisance to the way Divisions and Percy are portrayed. For all intents and purposes, Percy is an evil, power-hungry individual, who, in turn, makes Division evil. "Girl's Best Friend" pulls back on that slightly, with Michael insisting that the current task would be better for the world. After all, who's against destroying dangerous weapons? This thought festers in our mind until the end of the episode, when Jaden happens the chunk to Percy.
We see that Nikita is not a story about morality or doing to right thing. The main character, Nikita, Alex, and Michael, are all on the right side of the fight and, from what we can tell, moral people. The real story is that of deception, layers good and evil trying to outwit and outthink the other, sometimes pretending to be the other. This is where the ambiguity comes in and where Nikita is most interesting.
Score: 8.6/10
