Lynch was part of the CTU team led by Jack Bauer sent to recover Farhad Hassan in Forest Hills. As they were heading there, Jack instructed Agents King and Lynch to come in from the south, while he and Agent Owen would cover their flank. After they found Farhad Hassan shot, Lynch and the team transported his body to St. Julian's Hospital.
Lynch was later stationed outside the United Nations building offering security during the signing of the peace treaty. Several minutes before 3:00pm, Chloe O'Brian called him and asked him to find a schematic for the Hart Building. He met with Chloe in front of the building and handed her the schematics.
