Characteristics
O'Brian is exceptionally intelligent; in particular she displays extraordinary mastery of computer science. Spending most of her time behind a computer terminal, she is rarely sent on field assignments; however, she has demonstrated proficiency with weapons in Day 4, 5, and 8. She works very well under pressure, yet it is obvious when she is under pressure, that she has always demonstrated a degree of social awkwardness. Despite her lack of social graces, Chloe has gained several friends at CTU and has shown to have a great deal of loyalty to them. She helped CTU Agent Chase Edmunds take care of his daughter from a previous relationship after the child's mother abandoned Chase and their child. She even tried to pass the child off as her own, so as to keep Chase's then-girlfriend, Kim Bauer, from knowing. Before the start of Day 6, she andAppearances

Introduced in the third season of the series, Chloe O'Brian is a senior analyst at''24'': Season 4
Chloe continues to work at CTU as an analyst. She continues to help Jack (at the time, not a member of CTU) to follow the terrorists while risking her career. She is detained and fired when Director of CTU Los Angeles Erin Driscoll (the person who fired Jack) discovered Chloe is helping Jack behind her back. When Driscoll resigns and Michelle Dessler steps in, she is reinstated since none of the other CTU employees were as skilled as Chloe was. When the crisis ends later in the day, she, along with Michelle Dessler, Tony Almeida and former President David Palmer, help Jack to fake his death.''24'': Season 5
Chloe is given a love interest, a subordinate named''24'': Season 6
After the failed assassination of Assad via military helicopter, Chloe found an image of Jack rescuing the terrorist. She shared the information with Bill Buchanan, who conceded that from Jack's perspective, a rescue was the right action. Chloe suggests if Jack is right, then Fayed should be monitored. Buchanan agrees, and subsequently CTU obtains information that Fayed was indeed behind the latest waves of bombings. Chloe is later able to recover data from the hard drive of one of Fayed's men that he was particularly interested in a specific set of terrorists Fayed demanded be set free. Later, after Jack notices Curtis Manning's demeanor around Assad, asks her to find out if there is a past connection between the two men. She later confirms that Manning's military unit took heavy losses at Assad's hands and that Assad beheaded two members of Manning's unit on television. Jack uses that information to prevent Manning from killing Assad, though the price is Manning's life. When chatter is intercepted between Fayed and Darren McCarthy, a profile of the man able to arm the four remaining suitcase nukes is sent, though the message is badly degraded. Morris works on reconstructing the image, while Milo finds information that states Morris's brother has been exposed to the radiation from the Valencia bomb and is in a hospital. Chloe informs him, but while Morris wants to go to his brother's side at once, Chloe insists he retrieve the data. After Morris downloads an illegal program that will speed up the reconstruction of the data, he leaves, and Chloe kisses him goodbye. Chloe then monitors the retrieval to find that the engineer was, in fact, Morris. Bill has her call Morris via cell phone with Jack on the line, and Chloe jumps nervously after hearing gunfire erupt as McCarthy corners and kidnaps Morris from his car and put into his with the help of McCarthy's girlfriend, Rita. Chloe works to help locate Morris, who was tortured by Fayed into programming a device which would allow the detonation of the suitcase nukes. Chloe gives Jack the needed information in how to disable the suitcase nuke Fayed left behind after CTU assaulted his safe house. Afterwards, Jack and Chloe have a reunion at CTU where she thanks him for saving Morris's life, and she tells him she's glad Fayed didn't kill him. Jack thanks her for everything. She later visits Morris in the infirmary, but her attempts at compassion are dismissed by Morris's claims that he's responsible for Fayed ability to arm the remaining suitcase nukes. He tells her to go away. She later goes back to say they have a lead, and asks him to return to duty. He dismisses it as a ruse to get him to go back to work, and admits he's a coward. Chloe retorts he's pissing her off, and Morris says she can add it to his list of failings. Chloe slaps him, and he tells her if she wants to save somebody, save somebody who is worth saving. She tries to slap him again, but he blocks it. She tells Morris to stop feeling sorry for himself and get back to work. Later, she finds Morris is not at his work station. She investigates his palmtop, and calls his sponsor, who says she hasn't been in touch with Morris for years. Chloe confronts Morris in the men's room. He tells her he has a different sponsor now – who he ''did'' speak to on the phone – and berates Chloe for being 'obsessive' about his contacts. However, when Chloe leaves, he drains what is left of a bottle of whiskey down the sink. When Milo suspects that Morris has been drinking again, he asks Chloe to check Morris for any signs of alcohol. She reluctantly agrees, and walks over to him and kissed him, when he asked "What was that for?" she responded by saying "Just checking your breath." Later, she helps Jack to steal the bomb's schematics. However, Morris discovers her act and forces her to tell Bill. When Bill orders everyone to help Jack Bauer under presidential order, he excludes her saying that "I don't trust you" but he changes his mind in the next episode when he tells her he needs his best people working on this. Chloe is apparently upset and angry at Morris for forcing her to tell Bill the truth and the pair argue until Chloe's anger gets the better of her and she throws the fact that he armed nuclear weapons for terrorists, back in his face. Chloe insists that she didn't mean it but Morris puts in for a transfer out of Com and to no longer work aside Chloe. She is visibly upset and scolds herself for pushing the issue too far. Later, she attempts to apologize, but Morris tells her that their relationship is over. As Morris goes back to work, Chloe bursts into tears. Minutes later, Nadia notices that Chloe is not at her station and Morris claims not to know where she is. Later, Chloe confronts Morris over his decision to break up. Morris tells Chloe that he ended their relationship because he felt that neither of them would be able to move past the fact that he had armed the nuclear weapons. Soon afterwards, CTU came under attack and the entire staff, including Chloe, was taken hostage. Eventually Nadia, Jack, and Morris attacked the men holding them hostage and Chloe commended Nadia on her bravery. While at work, Chloe faints and is taken to the CTU medical department. It was revealed near the end of the final episode that she is pregnant. Morris, presumably the father, appears pleased at the news, and the two resume their relationship once again (in typical Morris fashion, he dismisses their breakup with a "Sod that!" comment).''24'': Season 7
Chloe does not appear in '' 24: Redemption'', the two-hour TV prequel, which aired on Sunday, November 23, 2008, she and Bill Buchanan first appear in the third episode of the season. Actress''24'': Season 8
In Season 8, Chloe is re-employed by the revived CTU, but is at times struggling with the new hardware, software and interfaces; dialogue between her and Head of CTU Brian Hastings ( Mykelti Williamson) indicates that Morris has lost his job and Chloe is keeping the family afloat. She is also subordinate to Dana Walsh ( Katee Sackhoff), who holds Chloe's usual position of Head Analyst, causing the insecure Chloe additional stress. Chloe quickly goes head-to-head with her co-workers when evidence is uncovered that implicates journalist Meredith Reed ( Jennifer Westfeldt) in an assassination plot against President Omar Hassan ( Anil Kapoor). Chloe is suspicious of the ease with which CTU obtained this evidence, feeling that Reed might be being framed by actual conspirators. Hastings refuses to follow up on her suspicions, even threatening her job if she takes time to investigate, so she recruits Jack to do it instead. As it turns out, Chloe's instincts are proved correct, leading CTU to the actual assassin, and Hastings formally apologizes and commends her actions in the official logs. Later, after Dana's behavior in relation to former associate Kevin Wade ( Clayne Crawford) affects her job performance, Chloe is then reinstated to Head Analyst, with Dana now reporting to her. In the 183rd episode of the show (Season 8, 6:00 am – 7:00 am), Chloe surpassed Tony Almeida ( Carlos Bernard)'s episode count of 115, becoming the character who has appeared in the most episodes of the show other than Jack Bauer. Perhaps appropriately, just after 8 am that day, Chloe is promoted to (Acting) Director of CTU, replacing Hastings. This puts Chloe in an abnormal position in regard to Jack: normally she helps him carry out clandestine operations in defiance of their mutual boss, but now she ''is'' the boss he is defying. This new dynamic is put to the test within two hours of her promotion, when Jack steals a helicopter to pursue justice in direct defiance of orders from President Allison Taylor ( Cherry Jones). Chloe sticks with the responsibilities of her position, ordering pursuit instead of supporting Jack; this is the first time in several years the two have pursued clashing goals. At the end of the 8th season (3:00 pm to 4:00 pm), Chloe manages to talk Jack out of assassinating the Russian president in revenge of a friend's murder earlier that day and gets him to agree to expose the conspiracy her way. Jack orders Chloe to shoot him in order to free herself from suspicion and to expose the cover up of Hassan's murder. Chloe refuses to go through with it until Jack points the gun at his own head, forcing her to either shoot him or having him kill himself. She shoots him in the shoulder. Coordinating with Cole Ortiz, she tries to get evidence collected by Jack vital to expose the cover up, but is stopped by Jason Pillar and CTU. After Jack is saved from death by President Alison Taylor's order, he calls Chloe and makes her promise to protect Jack's family, and along with President Taylor, plans to buy him as much time as she can for him to flee the country before the Americans and Russians come after him for his actions. Jack thanks her for all she has done for him since she joined CTU and forgives her for her actions during the day. Chloe has the distinction of speaking the final line in the series by saying "shut it down" to Arlo Glass in regards to the CTU drone. As Jack looks one last time towards CTU's monitoring, Chloe gives one final tearful look to Jack in CTU's monitor screen before the clock counts down to zero. In the Season 8 DVD bonuses, it is revealed that Chloe was arrested soon after the events of''24: Live Another Day''
In '' 24: Live Another Day'', four years after the end of Day 8, Chloe is situated in London and has taken to a new, darker appearance. Since being arrested for helping Jack escape, she has become a member of the free information movement and is working with a hacker group named Open Cell, which devotes itself to exposing government secrets. Her new goals are a stark contrast to the loyal CTU agent Chloe once was; it is suggested she was betrayed by the American government, at one point telling Jack not to judge her "after what he'sbeen through." At the start of the miniseries, she was being detained by the CIA for leaking thousands of classified DOD documents. Jack, allowing himself to be captured to gain access to the facility, frees her and then follows her to the hideout of Open Cell's leader, hacker Adrian Cross ( Michael Wincott). Chloe convinces her colleagues to assist Jack in locating Derrick Yates ( Joseph Millson), a former member of their movement who Jack believes to be involved in a planned assassination attempt on President James Heller ( William Devane). By this time, Yates had already managed to commandeer a U.S. drone and fire upon a military convoy in Afghanistan, killing two American and two British soldiers. Together, Jack and Chloe track Yates to an apartment complex, but are circumvented by the CIA's efforts to apprehend them. After losing Yates, Jack evades capture and escapes with Chloe. In the show's third episode, Jack discovers Yates' corpse, left behind by his female companion, Simone Al-Harazi (Emily Berrington). Chloe loses sight of Al-Harazi after being distracted by a passing family, after which she reveals to Jack that Morris and Prescott were killed as a result of her knowledge of Jack's disappearance following Day 8. Together, they return to Open Cell's headquarters in order to establish a cover for Jack to infiltrate the U.S. embassy in London and question Lieutenant Chris Tanner ( John Boyega), the man Yates had framed for the drone attack. However, Cross betrays Jack by botching Jack's cover; Chloe senses something amiss and warns him to escape, giving Jack enough time to create a diversion and enter the embassy. Throughout the rest of the day Chloe aids Jack as he searches for Margot Al-Harazi. Chloe manages to hack into Al-Harazi's video feed from her drone's cameras and fake President Heller's death and then track her with Adrian Cross' help. Jack kills Al-Harazi and stops an attack on Waterloo station, but Chloe refuses to have anything more to do with him, telling Jack it was good working with him again before rejoining Cross. After Cross receives the override device from Steve Navarro, Chloe tries to steal it but is forced by Cross to give it back. She is shocked to discover that Cross is working with Jack's old enemyProject CHLOE
Project CHLOE, a Department of Homeland Security surveillance technology development program aimed at protecting airliners from terrorist missiles, was named after Chloe O'Brian because ''24'' is former Homeland Security Secretary Michael Chertoff's favorite show.References
