Even though Nikita has only been gone for a little over a month, I can hardly remember what happened last time other than that the episode ended with Michael with a gun inside Nikita's loft, ready to get all the answers.
With a setup like that, "Covenant" has monumental expectations to live up to. If Michael catches Nikita and is free to interrogate her, wouldn't he find the truth, thus disturbing the genetic makeup of the show, which is of two women fighting against Division? Will Michael, who been questioning the morally of Division and Percy, switch sides?
The answer to those question is yes, but the motivating factor is worrisome. "Covenant" has a lot of scenes of Nikita being awesome at what she does, and for the CW viewers, slightly artificial romance. But the major plot development, Michael switching sides, only comes about after the writers reinforce the silly narrative about Percy being the evilest man in the world. There is no gradation with his character, only pure evil which must be improved. Thus, after Michael learns that his arch-enemy Kasim was actually recruited by Percy, he makes the decision to turn against Division. All his huge decision boils down to is a very logical reason for opposing Percy.
Score: 8.2/10
