SEASON 5
501 - DÉJÀ VU ALL OVER AGAIN
Nikita's participation in Center's evaluation of Section One has prompted shocking changes -- Madeline's suicide, Walter's transfer, Michael's cancellation, and Operations' non-promotion. Now Nikita insists that the head of Center, Mr. Jones, keep his end of the bargain by allowing her to make changes that would humanize Section One. But when Section discovers the formation of a new terrorist supergroup called The Collective, Mr. Jones forces Nikita back into the field and pairs her up with a new partner, Marco O'Brien. O'Brien was a cop who was forcibly recruited into Section four years earlier -- and along with Operations, Quinn, and numerous others, he has an axe to grind with Nikita. Will Nikita be able to survive not only the loss of Michael, but the very real threats from everyone around her?
502 - A GIRL WHO WASN'T THERE
Using a snooping device given to her by Walter, Nikita successfully hacks into her secret Center profile and discovers clues to her original recruitment into Section: a mysterious "M," and the possible identity of her father. Meanwhile, Quinn combines Birkoff's Artificial Intelligence technology with Madeline's profile and creates a holographic Madeline. At first, the A.I. Madeline seems to be an exact replica of the real thing, and Operations becomes obsessed with the idea of having Madeline by his side once again. But what he refuses to recognize is that the A.I. Madeline is actually undermining Section's ability to eliminate The Collective, the most powerful terrorist organization the West has ever seen. Now it's up to Nikita to stop Operations before Section's very existence is threatened.
503 - IN THROUGH THE OUT DOOR
Barely a year after Michael deprogrammed Nikita from the mind control process invented by Gelman and used on her by Operations and Madeline, Nikita begins to suffer sudden, painful aftereffects. The side effects threaten not only Nikita's health, but also her mission to capture The Collective's top bio-weapons expert. O'Brien covers for Nikita, but knowing that Operations is looking for any excuse to eliminate her, he teams up with Walter to help Nikita search for a cure. Unfortunately, finding one will require extracting a tissue sample from Adrian, Gelman's original test subject -- and Michael was the only one who knew Adrian's whereabouts. Luckily, the disk that Nikita discovered at the mysterious house contains the address of Adrian's last known location, suggesting that Michael, still on the outside, may be working on Nikita's behalf. But time is quickly running out, and if the process can't be reversed soon, Nikita will surely die.
504 - ALL THE WORLD'S A STAGE
Section intel has revealed that Massima Valenti, one of The Collective's major suppliers, is planning on acquiring and selling a shipment of deadly Anthrax rockets. To thwart the transaction, Section needs Mr. Jones to put his "Mick Schtoppel" character back into play, since "Mick" and Valenti have a shared history together. The mission requires Mr. Jones to leave Center and return to the field ó an incredibly risky move. Knowing that Mr. Jones will be outside of Center's protection, Nikita uses the opportunity to force Mr. Jones into revealing why she was recruited into Section One seven years ago. However, what Nikita discovers turns out to be even more shocking than she could have imagined.
505 - THE MAN BEHIND THE CURTAIN
After an extensive search which almost costs Nikita her life, she finally meets her father -- the real head of Center, and the real "Mr. Jones." Much to Nikita's chagrin, Jones refuses to answer any of Nikita's questions about her recruitment, and instead sends her on a mission to recover a computer disk intended for The Collective. She does, and the disk's contents confirm Jones' suspicion that there is a mole for The Collective inside Section. The evidence points to either Operations or O'Brien, and Jones tells Nikita to find out which one it is. However, Nikita's investigation reveals that neither O'Brien nor Operations is guilty, and therefore, the mole must be the one operative that no longer works for Section: Michael.
506 - THE EVIL THAT MEN DO
Operations has always regarded Nikita's relationship to Mr. Jones as a threat to his own authority, so he decides to take steps to remedy the situation. Sending Nikita on a mission to secure a computer hard drive containing The Collective's upcoming strike plans, Operations deliberately fails to provide her with an escape route in hopes that she will be killed. Nikita manages to survive, and when she tells Operations that she plans to inform Mr. Jones that he tried to kill her, Operations reveals he has evidence that Nikita helped Michael escape Section One. This means that if Michael truly is the mole, Nikita is ultimately responsible for Section's failure to contain The Collective, and if Mr. Jones discovers this, it could be the end of Nikita's new role in Section. Nikita and Operations travel to Center to argue their cases, and Mr. Jones is deeply disappointed in Nikita. Nevertheless, when Operations' jet is shot down on his way back to Section, Nikita and Jones must work together to find him before The Collective does.
507 - LET NO MAN PUT ASUNDER
When The Collective kidnaps Michael's son Adam in order to force Michael to hand over Mr. Jones, Operations risks his life to stop it from happening.
508 - A TIME FOR EVERY PURPOSE
Nikita must make a fateful choice regarding her future.
