Jane and the team investigate the murder of Titus Street, a software engineer whose car explodes right in front of a police officer. When the CBI learns that Titus was employed by a company that makes aerial drones for the US military, they realize that the explosion was actually the result of a drone strike. The team hits a wall when they learn how much of Titus' work is classified, but they continue to pursue the case by questioning everyone in Titus' life, including a disgruntled co-worker and the prostitute that Titus was sleeping with.Following Brett Partridge's death at the end of Episode 601, Jane and Lisbon's suspicions turn toward CBI director Gale Bertram. Jane also figures out that Red John learned about his past - including the 'happy memory' that he killed in the season five finale - from his old therapist, Sophie Miller, who has just turned up dead.
