Agent Reynolds was part of the team led by Larry Moss to storm the White House against General Benjamin Juma. After the successful raid, Agent Reynolds informed President Allison Taylor that the agents were confident that the terrorist threat had been neutralized though they were still searching for hostiles. When he told her that she would soon be moved to Andrews Air Force Base, she demanded to remain in the White House instead. When asked about the casualties, Reynolds replied that the number of deaths was still unknown but treatment was arriving for the injured. She finally ordered him to put her in touch with Vice PresidentMitchell Hayworth, and also requested that he call Dr. Lee Schulman at West Arlington Hospital hospital to check on her husband.
Later, Reynolds was among the 25-agent team—led by Renee Walker and Park—which raided the abandoned building at 1297 Rincon in the search for Robert Galvez. He was inside when the building was gutted by Galvez's C4 explosions at about 2:47am.
The name "Reynolds" is seen on the FBI map (see this image) during Day 7: 2:00am-3:00am. The character may not actually appear on-screen. It was not specified if Reynolds survived or was among those agents killed in the blasts.
