Alex's History
Alex is the daughter of the late Russian oligarch Nikolai Udinov and his wife who were murdered when Alex was a child. Nikolai owned the billion-dollar company Zetrov, which Alex was the sole heir of. She was saved by Nikita as she watched the rest of her family perish. Nikita was powerless to save Alex from anything else as she had to return to Division, and she gave Alex to one of Nikolai's associates. As a result, Alex was sold into sex slavery at very young age by her father's former associate, since he was afraid of retribution for hiding her.
To keep her from fighting against them, the slavers kept Alex with them by keeping her high and eventually forcing her to become a drug addict. For a few years, she had no choice but to stay with them to get her next fix. Nikita later finds and rescues her, as she tried years before, and forces her to get clean, much to Alex's irritation.
Alex brings this up to Amanda, saying that the slavers "had the decency to keep her high" as they held her captive, comparing this to Division.
After Nikita succeeds in helping Alex past the worst part of her addiction, she starts to train her both mentally and physically to be fit to stay one step ahead of Division. It was revealed in a flashback that it was Alex's idea to infiltrate Division, and that if Alex hadn't tried to kill herself in front of Nikita, she would never have told Alex the truth about Division.
To carry out their plan, Nikita and Alex rob a pharmacy and in the process Nikita shoots Kyle, a smuggler and target of Division. Nikita then disappears and Alex is arrested and blamed for killing Kyle. This attracts Division, her suicide is staged so that everyone thinks her dead and she is brought to Division. There, she claims ignorance about Division, its actions, her purpose there and the people around. She soon meets Jaden and Thom and despite animosity between Jaden and herself she joins their group to gain more info on Division. Jaden often felt Alex was stealing her thunder and, was jealous of her relationship with Thom. This leads her to info on operation Black Arrow. She then uses Shellbox to inform Nikita. In the meantime she still pretends she wants out of the Division, even going so far as trying to take Amanda hostage and demanding she lets her out in a failed escape attempt. She and Nikita contact each other through encrypted email when Alex is allowed on the computers.
Alex was working with Division to gather the Intel and resources she needed to reclaim her birthright. She claimed that she was merely using Division (although Amanda would argue otherwise) but had gone on a number of missions for them.
Alex, through a series of events, was also being manipulated by Percy. At this point, through blackmail, Percy seemed to have manipulated Alex. Where Alex was once a mole for Nikita, she appeared to be becoming one for Percy instead, though unknowingly.
Eventually she managed to reconcile with Nikita and was able to betray Amanda and Ari. She inevitably retook her father's empire though handed control over to an old friend and rescued her mother. She is now currently working with Nikita. She later assisted Nikita in her raid on Division, which ended successfully with the deaths of Percy and Roan, and with Ryan Fletcher placed by the US government to be Division's Director.
After the reinvention of Division, Alex takes on a leading role alongside Nikita, Michael, Birkhoff and Sean and becomes a part of the inner circle under Ryan Fletcher. After a mission with Nikita, Alex is kidnapped by Amanda and held in a facility in South Ossetia and held for ransom in exchange for Ari, who Amanda needs to access the Black Box. During her incarceration she develops a bond with a nurse named Larissa, who is being forced to work for the Ossetians after they killed her husband and daughter. Division mounts a rescue and successfully rescues Alex, but she insists on going back to rescue Larissa, who is killed in the ensuing shootout. This deeply affects Alex, who sees the failure to rescue Larissa as Nikita's fault.
After returning to the States, Alex becomes opposed to the continuation of Division, outwardly opposing Nikita and the dossier missions handed to them by Danforth. When a mission to assassinate the president of Chad is compromised, she and Birkhoff work together to find information to use against Danforth and discover that he has been secretly training SEALs in a killhouse mock-up of Division in preparation for a clean sweep. When she informs Nikita and the rest of the inner circle of the situation, they realize Danforth gave them the dossier missions with the intention they would fail and he would be able to execute a clean sweep. Deciding that everyone needs to know the truth, Alex goes in front of Ops and explains the situation to all of them. She and Nikita later seem to reconcile their differences as Division's safety is guaranteed when Nikita captures the rogue agent working for Amanda who botched the assassination, as well as use information from the recently decrypted black box to hold Danforth at bay and have him convince the president to cancel the clean sweep.
Following this there seems to be a mutiny brewing within Division after Sonya discovers someone hacking into the Tracker program in the server room. At first Alex seems indifferent to the mutiny, but is brought around when Ryan explains that while one or two deserters can be written off as rogues, a significant number of agents doing that comes to a "tipping point" and can only be covered up by a clean sweep. Ryan puts Alex and Sean in charge of the investigation and with Sonya's help and some dummy programming planted by Sean to use as bait against the saboteur, they identify and capture Rachel. As Sean is sent to the infirmary after Rachel stabs him during the arrest, Alex and Ryan interrogate her. Rachel refuses to give up the names of her co-conspirators, but she slips up and mentions "tipping point" and Ryan realizes that Rachel was covering for Alex, who is the real mastermind behind the mutiny and the only person he mentioned the word "tipping point" to. Alex then begins to say that if Division continues, they will all end up dead like Larissa and "the other girls", referring to the ones she was sold into sex slavery with. This leads to her shooting Ryan and breaking down; a flashback reveals that Amanda tortured Alex in South Ossetia, brainwashing her in an attempt to take down Division from within. After regaining her composure she tells Rachel to take the fall and concocts a cover story to protect her own cover. When Nikita and Michael return from their mission and visit a comatose Ryan in the infirmary, Alex tells them that Rachel's co-conspirators hacked the doors and Rachel was able to take Alex's gun and shoot Ryan before escaping.
After finding out Amanda is alive, Nikita and Alex prepare to take her down. Alexandra is now in a relationship with Sam/Owen. Alex is taken by the CIA and questioned about her involvement with Nikita at a black site. Just as they are about to move her, Michael and Sam/Owen infiltrate the site and help Alex escape. Some time later, Alex is a at human rights conference with Owen as her body guard. Alex asks Owen if he would like to have dinner with her.
Alex is known to have many walls that protect herself from being caught emotionally off guard. Amanda even admits that she has trouble getting through to the real Alex. "The girl's like one of those Russian dolls; you open one version of her, only to find there's another hidden inside her." She does not talk about herself or her past much. Though when she does, she talks to Nikita and later even to Amanda.
She also suffers from panic attacks due to certain things that trigger somewhat suppressed memories of her past, such as being under a car reminding her of being under her bed as she watched her family die.
Despite Alex and Nikita's closeness, she sometimes lies to Nikita to hide her true feelings. She also uses walls to suppress the fact that she is Alexandra Udinov, and claims to just be Alex, which Nikita taught her to hide away who she really is to make her more believable to Division. Though she eventually accepts that she can not hide who she is, as it's also no longer needed to hide her true self. Alex also has a hard time conveying her emotions, such as if she likes a boy. She tries not to get attached due to it having dire consequences, though she does sometimes reveal her emotional state. Sean once jokingly said "Wow, those walls you got there are tough. What do you Russians build with anyway? Field stone. Petrified potatoes?" He claims that sometimes when he's with her he can see a crack in her wall and she gives him a look that shows her pure self.
Alex gives off a mature exterior, though sometimes when she opens herself up, she appears to still be an immature kid underneath, despite everything she's been through. She also thinks that she can take care of herself and thinks she doesn't always need Nikita to help her. Alex doesn't build many bonds with men, only Michael and Sean are known to sometimes get something from Alex. However, Alex leans towards the mother figures, like Amanda and Nikita, to give her comfort and support. Despite the fact that Amanda and Nikita are enemies, Amanda shows affection for Alex in her own way.
Although Alex can for the most part control herself from not taking drugs or alcohol, she isn't allowed to take any type of drugs, such as pain pills, due to the fact that she might relapse. Therefore, if Alex gets shot, breaks an arm, or is seriously injured, she isn't allowed to take morphine or any other type of drugs that will help dull the pain. After Alex takes a bullet to the arm for Nikita, she isn't allowed to go on missions while she is still healing. While Alex recovers, it forces her to remain still and recollect her thoughts. However, Alex is not the type of person to give up easily. Division is her life, and it's all she knows and what she considers home. Now that she has time to think, it isn't a very good thing. Her dark past is something she rarely talks about, and some repressed memories come back to her as she has time to think about it.
At one point, when it appears Alex is starting to relapse into drugs when taking pain pills that she and starts to get addicted to them. She takes them after a heated argument with Sean in the medical facility, which is stocked with drugs, and because her bullet wound started to hurt. After Alex gets sick of waiting at Division and hurt after her and Sean's conversation, she tells Nikita she's going on the mission to Amanda's house with her. Nikita allows her reluctantly, which results in Alex taking a heavy beating from a man twice her size and leaving her in immense pain. When she gets back to Division she secretly takes more pills, and it appears she is slowly starting to get addicted to them. Alex often plays the physical and emotional punching bag of others. She can be cool headed in one moment, then fierce and passionate in the next. She is playful and snippy with many people such as Amanda and Owen. But then she can be gravely serious and no nonsense if it is a topic that effects her emotionally.
