Won't Get Fooled Again

Gideon and the BAU track down a copycat bomber who has been terrorizing Palm Beach, Florida. They determine the bomber is mimicking Gideon's nemesis, Adrian Bale (Tim Kelleher), the man responsible for murdering Gideon's team in Boston several years earlier. When a hostage appears with a bomb around his neck, Gideon must swallow his pride and ask Bale for help in disarming the bomb after the copycat bomber blows himself up when Hotch and Elle attempt to arrest him. Based on Mark Hofmann.
