Charles Langdon is former President Robert Richmond's Chief of Staff who was thought to have been deceased, but in reality was in hiding.
After feeling immense guilt for revealing information leading to the Capitol Bombing, he began helping out Hannah Wells in her investigation into the conspiracy. Eventually, he decided to turn himself in to be interrogated and gave out what he knew about the conspiracy to Hannah and President Kirkman.
According to Charles during his interrogation, Charles met and fell in love with a woman named Claudine Poyet, but the latter never returned his affections. She began asking him for inside information on a government highway project, but then came the event where she asked him for the threat assessment on the Capitol renovation; room 105. From that point, Charles began his efforts to stop whatever she was doing.
Some time later, he was blackmailed by Claudine to name Tom Kirkman the designated survivor, under the threat that he would die. He then attempted to drive to Alexandria to meet with the FBI director. However, his car was hacked and it drove off a bridge. Charles made it out alive, but just in time to see the Capitol explode. He was then thought to have been deceased by the general public.
He began aiding Hannah Wells in her investigation into the Capitol bombing, even giving her clues about a bomb shelter that was secretly built beneath the building. Hannah then located Charles in a secluded home in the woods. While she asked him questions, Charles talked about how hard it was to hide from the conspirators and how the conspiracy was bigger than she thinks. They both were attacked by an unknown individual who began firing shots at them. Taking advantage of the sudden violence, Charles escaped the scene in a vehicle.
Charles met up with Aaron Shore, who were unknowingly being watched by the FBI. While they were inside a church, Charles told Aaron to tell the President that he wanted witness protection and left before the FBI could reach him. However, Charles decided to turn himself in to give information on what he knew about the conspiracy and to tell President Kirkman that he was made the designated survivor because he appeared the least qualified.
