Agent Keyes worked for Homeland Security. He had planned to prove that the Halliwell sisters were magical, and concocted a plan with Inspector Sheridan, though she was eventually killed by Zankou. He then sent the SWAT team around the house, ready to storm the place and spotted the sisters inside before Darryl Morris warned him to stay put. An explosion took place shortly after. Since no body was recovered, Agent Keyes fake-believed that the sisters were dead so they may resurface again, and prompted Agent Murphy to keep an eye on them.
