Conspiracy
Susan's contact
Speaking to Walker under duress
Susan Walker, who was trying to root out a dangerous conspiracy in Washington, D.C., contacted a trusted associate. The contact, an ex-Department of Defense agent, planned to help her dismantle a terrorist scheme to sell missile launch codes. When she called him, he was under duress from a blond-haired assailant and was forced to lure her into a trap. After he ended the call, the contact was then killed by a gunshot wound to the face from the assailant.
- The ex-DoD contact appeared in 24: Conspiracy.
Day 5
CRT agent
Attempting to disarm a nerve gas canister
At Tyler Memorial Hospital, a chemical response team was called in to disarm a canister of Sentox nerve gas that was planted by Viktor Grigorin. One of the CRT agents told Curtis Manning that it would not be possible to disarm the device in 60 seconds, which was all the time they had. Curtis decided to run the canister out of the hospital, and there the CRT team placed it inside a sealed containment unit.
- The CRT agent was played by Angelo Perez in "5:00pm-6:00pm."
Stenger's federal marshal
Trying to remove Jack Bauer from Stenger's cell
Collette Stenger made a deal with CTU Los Angeles for immunity from prosecution, if she revealed the source of the secret information she sold to Vladimir Bierko. As part of the deal, she would be protected from interrogation, and a Federal Marshal was assigned to guard her. When Jack proved that Stenger got her information from Christopher Henderson, and not Audrey Raines as she had claimed, her immunity deal was ready to be nullified. Jack rushed ahead to interrogate her before the paperwork was filed. The Federal Marshal tried to halt him, so Jack knocked him out with a blow to the face. Jack threatened Stenger with the Marshal's weapon, so she surrendered more information about Bierko's next target, a gas distribution plant, which turned out to be the Wilshire Gas Company.
- The Federal Marshal was played by Matthew Jones in "9:00pm-10:00pm."
HS field agent
Finding incriminating evidence at Bill's house
Just after 2am, a number of agents from the Department of Homeland Security led by Ed arrived at the house of Bill Buchanan in search of Chloe O'Brian. Buchanan resisted their attempts to gain access without a warrant, and verbally stalled Ed while Chloe got away. Ed's assistant, one of the field agents, noted that a specific file visible on Buchanan's computer could only have been accessed by Chloe, indicating that she was present earlier. Karen Hayes, who was in charge of the team but wished to help Chloe escape, told the team to bring Buchanan to CTU.
- The Homeland Security field agent was played by Aaron MacPherson in "2:00am-3:00am."
HS staffer with Morris
Morris O'Brian flirting with the staffer
Chloe O'Brian got security clearance to invite Morris O'Brian, her ex-husband, into CTU Los Angeles to help her with a project. The project was to outfit a micro-transmitter for Jack Bauer to place on President Charles Logan, but Chloe lied to Bill Buchanan and Karen Hayes that it was to recover a critical piece of evidence (a deleted audio recording). One of the first things Morris did at the CTU building was to flirt with an attractive staffer who had arrived with Hayes from Homeland Security. Chloe had to get his attention for him to leave the woman.
- The HS staffer was played by Kate Rene Gleason in "5:00am-6:00am."
Chinese agent
Jack allegedly gets a call from Kim Bauer.
Soon after President Charles Logan was arrested for his crimes, Chinese operative Cheng Zhi managed to capture Jack Bauer. Cheng did this in response to an illegal raid on a Chinese consulate, 18 months prior, during which Jack abducted terrorist supporter Lee Jong, and during which Consul Koo Yin was accidentally shot by his own men. Cheng used this operative, who was disguised as a Secret Service agent, to trick Jack into thinking he received a private call on a ground line from Kim Bauer. When Jack answered the phone, three other masked Chinese operatives kidnapped him. On board the container ship, this agent was again briefly visible (having a conversation with Cheng) when the other three operatives brought in Jack, battered and unable to even hold himself up.
- The Chinese agent was played by Charles Chun in "6:00am-7:00am."
Day 6
Russian consulate agent
Searching for Jack Bauer.
At the Russian consulate in Los Angeles, a consular agent spotted Jack Bauer as he was walking around on the grounds at about 5:36pm. He asked (in Russian) what Jack was doing, and Jack replied (also in Russian) that he was merely guarding that area. The agent walked off.
Later, while Jack was held prisoner at the consulate, the agent informed Consul Anatoly Markov that the perimeter was secured and there was no way Jack could escape. He was ordered to shut down the phone lines and DSL.
- The agent was played by Boris Arsoyev in "5:00pm-6:00pm" and "6:00pm-7:00pm."
Day 7
Burnett's federal marshal
Monitoring Jack Bauer's interrogation.
A federal marshal was assigned to guard Ryan Burnett at Kennedy Memorial Hospital. After Juma's siege at the White House, Ethan Kanin ordered the marshal to prepare Burnett for an interrogation in his recovery room. At 8:41, he met with Larry Moss and Jack Bauer, and informed them that he had locked down the entire hospital floor and had Burnett's room equipped with two cameras. He also told the two that Burnett was still regaining consciousness as his heavy dose of sedatives continued to wear off. He then introduced them to Dr. Wyndham who would finish preparing Burnett for the interrogation. He led Jack to the room, opened the secure door, and returned to watch the video feed with Moss as Jack interrogated him. When Quinn secretly disrupted their surveillance, he tried to regain the sound feed. When the system returned and they saw Burnett murdered, he rushed in with Larry and the others, only to find that Jack had escaped.
- The federal marshal was played by Glenn Davis in "8:00pm-9:00pm."

A N.E.S.T. technician disarming a bomb.
This N.E.S.T. technician arrived at the New York City alley on 93rd Street and Amsterdam where Tarin Faroush had left the deactivated radiological bomb. As he used a small robot to secure the bomb, he informed Jack Bauer that the bomb was constructed with the nuclear rods they were looking for, wrapped in enough C-4 to destroy Manhattan. Jack told her to call CTU as soon as he secured it.
- The N.E.S.T. operative was played by Brenton Schraff in "6:00am-7:00am" and "7:00am-8:00am".
