6. Fire and Brimstone

With the new clue in mind, Jane arranges to gather the remaining Red John suspects – Sheriff Thomas McAllister, Reede Smith, Gale Bertram, Ray Haffner, and Bret Stiles – in one place in hopes of uncovering the serial killer's true identity. Using the information Kira Tinsley gave him before she died, Jane, brandishing a shotgun, makes the five suspects show him their left shoulders revealing that McAllister, Smith and Bertram all have three dots tattooed on the left shoulder—meaning that one of those three is Red John. Lisbon (whom Jane abandons at beachside while en route to the rendezvous with the suspects at his family home) requisitions a car to arrive at Jane's house, and just as she is about to enter, an explosion occurs, throwing her back.
