Day 3: 12:00pm-1:00pm

Jack and Chase lead the search for Saunders' accomplice in the station of the Los Angeles Subway. While they are waiting for their team to search, Chase informs Jack that he is requesting a transfer out of the field to ensure his safety for the sake of Kim and his daughter while still serving his country. Jack commends his decision.

Wayne returns to the President's office and informs him that he retrieved the pill bottle, but that Julia shot Sherry and then took her own life. Both brothers are visibly shaken. Wayne attempts to push aside his grief by immediately strategizing how to publicize the incident to the press. David is both shocked and angered by his brother's perceived callousness.

Mrs. Ortega comes to CTU to claim Gael's things. However, upon seeing Saunders in person, she becomes angry and shoots him. Security attempts to regain order at CTU while saving Saunders' life, but he dies.

The accomplice manages to escape the subway and make his way to a nearby junior high school. Jack and Chase enter the school and announce that everyone remain in their classrooms. Jack and Chase split up in order to find the suspect. Chase is led into an empty science lab where he struggles with the suspect. Upon Jack's arrival, the suspect is restrained, but there is one complication-the device designed to contain and then release the virus is now securely fastened to Chase's arm-he claims it was the only way to secure the fugitive. Jack, with the assistance of another CTU agency, requests assistance in disarming the release mechanism. When he fails to disarm it, Chase insists that Jack use a fire axe to chop off his arm and take the device to a safe location before the virus is released. Jack manages to sever Chase's forearm and take the device to a secure refrigerator where the virus is released into an airtight container.

In a phone conversation with President Palmer, Jack informs the President that the virus was contained and that Chase was able to get into surgery in time that his arm could be reattached. Palmer also informs Jack that he has decided to end his reelection bid. Jack asks him to reconsider, but Palmer's mind is made up, and he expresses hope that the two can become better friends once he is once again a private citizen.

In the solitude of his SUV, Jack breaks down, overcome with emotion. His solitude is short, however, as he receives a call that the suspect is ready to be questioned.
