A mission is going out ... Nikita runs after the operatives, bringing the leader (Chuck) his gear. He is sorry she is not joining them, she flirts back that they probably thought they had too much fun together last time. Michael interrupts them abruptly, reminding them that their absolute priority is "the trigger". Chuck winks at Nikita as he disappears through those special mission doors (I really wonder where they lead to).
Inside a house, a completely normal looking couple (Helen and John Wick) sit in front of a fire. John Wick presses a few buttons on a mobile phone - and actives the bomb. Michael tells his operatives to evacuate, but it's too late: The bomb detonates, Chuck and the rest of his team are dead.
"Bring in everyone", Madeline says, "this is now priority one".
Nikita stays behind, staring at the screen on which the calamity was broadcasted, grieving for the lost colleagues.
***Mission briefing: Operations tells them who the Wicks are. Long-time arms dealers, small fish until recently. But now, they are believed to be in the possession of a nuclear trigger, a highly valuable, classified device. They trust nobody but each other and are tough nuts to crack - but Section believes they have found a weakness. And Operations looks straight at Nikita. Uh-oh.
Back inside, Helen Wick is getting a phone call; it's a private detective and he says: "I'm pretty sure I've found her". In a surprised daze, she tells him to pick her up and bring here to the house.
In a white room. Madeline, in black, is interrogating a man who is the middle man between the Wicks and the buyers of the trigger. But Section doesn't know exactly what group it is.
"Do you think there's anything I won't do to get this information from you?", she asks in a dispassionate voice.
"I can't tell you anything I don't know", the prisoners retorts, "You can torture me all day and that won't change."
"It's a deal."
They are able to narrow it down to three potential group, but that's it. Specifics? They've got nothing. Operations has a fit and shouts at Madeline and Michael. What about Nikita? No word from her for the last six hours, Michael says, which is probably a good thing. And Madeline thinks that they will have leverage if Nikita forms a bond with Helen Wick. Operations repeats "if ... if?!". Ah, what a grumpy old man. He calls back Michael and tells him that he has no intention on failing this one ... Nikita may have "to sacrifice". If Helen Wick really believes that Nikita is her daughter, she may not be able to bear the pain they inflict upon her daughter.
It is night and Nikita sneaks outside to secure the package. There is heavy security on the perimeter. But the Section-trained Nikita manages to break into John Wick's office (which is in a separate house). She puts on special goggles and sees the laser beams crisscrossing the office with them. She manages to disable them and starts searching everywhere (not sure for what). She then takes pictures with a small camera (again not sure of what). John arrives outside in his car. Nikita hurriedly re-assembles the alarm ... but Wick is already in.
He switches on the light and disables the alarm. He then goes to the safe, which is hidden in the bookcase (I guess she was looking for that!) - and puts the key to the locker in. Nikita, who is hiding underneath a small table, is taking pictures.
"We're going to have to use Nikita", she says. "There's no way to avoid it. Prepare yourself, Michael".
Wick is entering the room behind Nikita, who is still busy uploading images, seemingly unaware of him. When he asks what she is doing, she whisks around - but plays all innocent. Helen allowed her to use the computer, she hopes that's not a problem. He asks what "that" is: a digital camera, of course, Nikita says and takes a picture of him.
What did she do to Helen? he demands to know. She'll be fine, Nikita says, if he behaves.
"Who are you?" he wants to know and she replies: "I'm a friend of Chuck's".
Later, she goes and wakes Helen, who is understandably disoriented. She asks where John is and Nikita says that he left a while ago. Helen is trying to reach him on the phone, because this isn't like him at all (they have a very important meeting). John doesn't pick up, but there is someone at the door. A "Detective".
"The trigger", Michael replies.
"You killed John because he didn't tell you", says Helen, breathing heavily, "do you think I will?"
"Continue", says Michael.
But Helen is not talking, even after much more brutality against her "daughter".
Michael hesitates for a moment and then says: "Kill the girl".
Nikita wakes up - her face is cut, bruised, swollen, and one of her eyes is completely bloodshot. Madeline smiles sweetly - and thanks Nikita for "doing her job". The snake leaves, but Michael stays.
"I'm sorry it had to come to that", he whispers.
"Don't be", says Nikita, "I'm getting used to how things are".
He gently touches her right brow and turns to leave.
"Get some rest", he says.
While the Nikita in Episode 4 was still naive and much too trusting of Section and everybody else around her, the Nikita in this episode accepts her new life; she accepts who she is now and she accepts her own pain and suffering as a means to accomplish the greater good. She even identifies with Section (or at least some people she likes in it) and takes revenge for a colleague operative who lost his life at the hands of this episode's friendly neighborhood terrorists.
Her interactions with Helen Wick are touching. Sure, the woman is a brutal terrorist - but we do not see that side of her. We only see her "weakness", which is the loss of a daughter. And Nikita, who has grown up without love, receives love from her. To her, Helen really becomes like a mother; a mother she never had, but always wanted. The two women truly bond - even if it is all a lie, Nikita's feelings for her are not. At the end, she asks for a last kindness towards her; to let her believe she has found and saved her daughter.
In this episode, we also see how brutal Operations and Madeline can be - and how little they value life. They ordered to have Nikita brutally beaten and possibly killed in order to get the necessary information about the trigger. Operatives are "material" - they are expendable. They do acknowledge that Michael has some kind of special relationship with Nikita (telling him to prepare himself) but they also send him to order both the beating and the killing. We see Michael trying to prevent this "sacrifice" (i.e. by telling Madeline that they will find out in time, that they'll "tap into something"), but he isn't successful. We now realize that he is caught in the middle, always torn between his loyalty to Section and his feelings for Nikita - a dilemma, which doesn't seem to have an easy solution.
