Renee Walker

Renee Walker is an FBI special agent active in Washington, DC

Before Day 7
Renee Walker and her colleagues investigated a string of technology thefts carried out by an underground group. From a surveillance video, she isolated an image of one of the felons, and identified him as Tony Almeida. Walker had Almeida's grave exhumed, as Tony was believed dead, and DNA testing proved that the body was not his. Walker then made an effort to track down Tony's old partner, Jack Bauer, to assist them.

Day 7
With a subpoena for Jack Bauer, Agent Walker and her partner Agent Teller interrupted a Senate investigation led by Senator Blaine Mayer. She transported Jack to the FBI headquarters and briefed him there about the national security threat presented by Tony Almeida and his group. When Jack simply refused to believe that Almeida was still alive, she broke the news to him that the body in Tony's grave was not Tony's own. Despite Jack's constant insistance, Renee said that Tony was involved in some extralegal activites, not working in assistance with any government agency. She encouraged Jack to work with Sean Hillinger to track down Tony's whereabouts, which led them to Gabriel Schector, a former off-books supplier of Jack and Tony from their CTU days. They went to see Schector, but he was assassinated by agents of Tony before he could say anything. The building was sealed off after a call from Renee, and the sniper, Alan Tanner, was discovered by Jack. Renee and Jack pursued the sniper on their own to make sure that whoever compromised the FBI would tell no one else what they were doing.

Washington Office FBI Director Larry Moss called in to Renee to find out where she was. She made up a story about following a lead, but Moss did not seem convinced. Renee and Jack tracked Tanner to a containment ship, where they took him out. Jack managed to shoot out a surveillance camera, which attracted the attention of some of Tony's men, who came out and began to attack Jack and Renee. Masters was shot, and Renee and Jack split up inside the ship. Renee found a computer deleting all systems, and was unable to stop the process. Meanwhile, Jack managed to find Tony and chased him outside. After an intense fight Jack managed to overpower Tony. Renee arrived and told him that the device was gone. At that moment, Moss arrived after tracking Renee's phone.
