Larson

Larson was a security guard at the CIA London station during Day 9. At around 7:45, he was guarding one of the exits of the building, when Head of Station Steve Navarro came and informed him there was an alleged security breach. Navarro exited through the door and instructed Larson to not let anyone come through. Shortly after, Jack Bauer held a gun to Larson and after taking his security credentials, he knocked him down.
