Margaret was a waitress who worked at a diner. The night after Day 8, Jack Bauer stopped at a diner somewhere in Pennsylvania, and Margaret poured Jack a cup of coffee before taking his order. Sometime later, after Jack and Chase Edmunds assaulted two mechanics sent by Mike Roker, Thomas Hadley and his FBI team arrived at the diner and questioned the witnesses. Margaret admitted that she saw Bauer with a possible accomplice, but that there was no video evidence, since the camera in the diner didn't work. She later gave a statement to Deputy Roe, along with the other witnesses. (Deadline)
