24: Day Zero

Nina Myers approaches Jack asking about his life at home with Teri. Jack says that things will be fine. Devin, a computer tech, who is watching their suspect through surveillance, asks Nina about the intelligence on the suspect, Laszlo, making Nina doubt about their correct course of action. Jack asserts that they're right, but Nina says that George Mason thinks they're wasting time, saying they have been watching Laszlo for 9 weeks. Jack says that they'll be waiting for when he makes his move. The surveillance goes down. Jack has Nina watch the building and open up a new channel, and leaves with Devin, guns drawn.

Jack is on the phone with Nina. Devin is in the room with Nina, looking through the window with binoculars. Jack asks her for the bomb's specs, but Nina says that there's no time for that, and that Jack needs to get out. Jack needs to salvage Laszlo's files on his computer, so Nina has Jack put through to Jamey Farrell at CTU.

Nina and Devin run to the pile of rubble. There they find Jack half-buried, but alive. He crawls out and Nina tells him that Medical is on their way to check him out. As they wait, Jack gets a call from George Mason and tells him that it was a setup and that they will discuss it more when Jack gets back to CTU. Jack then gives the flash drive to Nina and asks her to work on it by herself.

Mason criticized the fact that Laszlo was killed regardless of CTU's surveillance. Jack, arm in a cast, believes that Laszlo was getting information from someone inside CTU, making Mason believe that a CTU agent had Laszlo killed. Jack tells Mason to bring Division into the investigation, but Mason denies this request. Jack presses the issue about someone within CTU working against them.

An agent walks up to Jack and tells him that his wife was on the line. Jack picks up the phone and talks to Teri. She tells him that Jack should consider changing his billing address because she's still receiving Jack's bills. Kim Bauer is seen sitting on the couch during the call. Jack says that they should talk about their relationship status more before officially changing his address. Teri agrees to talk about it later. Jack tells his wife that he wants to speak with Kim, but she doesn't want to speak with him. Teri says that Kim is having trouble adjusting to the separation. Jack has to get off the phone when Devin tells him that there's a problem with Nina.

Mason asks Jack if he's sure that the files are gone; Jack concurs. Mason reveals new intelligence that the codes are set to go on market shortly. Jack re-expresses his concern about a traitor in CTU, and Mason tells him to go home and get some rest.

Jack asks Devin if he was working for Laszlo, and Devin says that he needed the money. Jack demands the names of Devin's buyers, but Devin won't know until the transaction initiates. Jack wants to know how to stop the sale, but it's apparently too late. Jack scolds Devin for betraying his country. Devin simply responds by saying that there's a lot of money in selling information, but Jack cocks his gun at Devin's head, claiming that he won't ask again. Devin says that someone else is involved, and is about to give up the name, but a shotgun appears out of another car's window in the parking lot, shoots Devin in the forehead, and drives away. Jack shoots after it, but his gun is empty.

Nina, Jack, Mason, and Tony are meeting in the parking lot. Jack summarizes what happened with Devin, and that someone else took him out, supposedly his partner. Jack asks Mason if he called for any help from Division, but Mason says he didn't call Division because he didn't believe in any internal threat previously. Mason says that no one will want to work with him if he investigates everyone. Nina says that she'll work with Jack; Mason sarcastically wishes them both luck and walks away with Tony. Jack tells Nina that he moved out, and she asks him how his arm is. Realizing that he's having a bad day, Nina offers to buy Jack a drink, to which Jack feels obliged. He walks away with Nina, arm around her back. Tony sees the entire scene.
