This week's Nikita is slightly reminiscent of last week's episode: after chasing a Cleaner down to Mexico, now Nikita and Owen are in pursuit of another one, who really can't let his ex-wife go. No, literally, he's holding her hostage.
Nikita is wandering around an art gallery, snarkily remarking on how its entire inventory is stolen, before she introduces the art dealer Angela to her boss - who happens to be played by Owen. While he attempts to distract the art dealer and struggles at it, Michael directs Nikita elsewhere, so that she can break into a safe.
Unfortunately, Owen's horrible conversation skills mean that the art dealer notices her phone is missing, and she alerts security just as Nikita is cracking the safe. Thankfully, she emerges just in time, claiming that she found the art dealer's phone in the ladies room and ushering Owen out before he can do any more damage.
When they return to Division, Michael takes Owen to task for his inexperience working undercover, and Nikita jumps to his defense. "Would it be insensitive if I gave him the finger?" Owen wonders aloud, while Michael goes to have Robo-Hand looked at and runs into Sean. The two have an awkward moment of male bonding before Alex interrupts, and it's clear that things are still weird between Alex and Sean. "You haven't seen her in what, a month?" Michael asks Sean, advising him to "let it go."
Apparently Ryan has the day off, because someone else provides the exposition this week. Birkhoff explains that Angela also deals in stolen military technology from China, and that she got it from a former Division agent named Ray (guest star Matt Bushell), who traded it for a bunch of nasty weaponry. Nikita wonders what or who Ray is targeting. Cut to Pennsylvania, where a young woman named Kate (guest star Anna Hopkins) is worried that her ex-husband Ray is stalking her. Yes, it's the same guy, and he's sitting in her living room. Ray shoots Kate's new boyfriend before he abducts her. At least he lives, because apparently he was an off-duty cop still wearing his bulletproof vest.
The next day, Nikita and Owen stroll up on the crime scene pretending to be FBI agents, knowing that since Ray was supposed to be dead, if they don't keep things quiet, Division will be exposed. Kate's boyfriend, Jason (guest star Josh Braaten), wants to know what they're doing there and Nikita tries to convince him that Ray isn't behind it. Owen opens his mouth again to retort that Jason shouldn't even be on the case, causing Michael to do his "are you kidding me" expression that Shane West is so good at. After that, Michael tells Nikita to keep Jason close, so she asks him to stick with them as a "special advisor."
