Renee Walker was an FBI special agent from the Washington Field Office. She was involved in investigating the technology thefts prior to Day 7 and was an integral agent in bringing down the threats that arose on Day 7. Upon meeting Jack Bauer she was horrified at his willingness to do whatever was necessary to follow a lead. However as the day progressed she began to see the necessity behind Jack's actions and realized that the only way to bring down Alan Wilson, the main conspirator for the events of the day, would be to act as Jack would have done.
