120	4	"Red Listed"	Eric Laneuville	Rebecca Perry Cutter	October 20, 2013	4X5604	7.75[12]
When a list of fake Red John suspects is stolen, the innocent men named on it find themselves in danger. Madeleine Hightower and Bob Kirkland return. The existence of a conspiracy using the identification phrase "Tyger, Tyger" amongst California's Law Enforcement personnel is revealed. This suggests that Red John, known for his fascination with Blake's poem, may have strong connections to this organization. Bob Kirkland is murdered by Reede Smith, who tells a police officer to say that he killed him because he tried to run away, and they seal the deal by saying "Tyger, Tyger" (which indicates that they are part of the secret organization). Jane's list of suspects drops to five.
121	5	"The Red Tattoo"	Tawnia McKiernan	Eoghan Mahony	October 27, 2013	4X5605	8.82[13]
The CBI team is dispatched to investigate the murder of a member of Visualize. Jason Cooper and Ray Haffner arrive at the crime scene and Cooper tells Lisbon that Haffner is invited by the Lieutenant Governor to join the case -- much to Lisbon's and Jane's dismay. The case seems to lead to the killer being in two places at the same time. Meanwhile, Cho meets a woman at the victim's gym while canvassing. The woman is caught placing a bug in Cho's desk at the CBI by Jane and is questioned. The woman turns out to be a private investigator hired to keep an eye on the investigation. At the end of the case, Jane confronts Cooper about hiring the PI to bug the CBI, but Cooper denies the accusation. Jane then realizes that Cooper is telling the truth and that Red John hired the PI to bug the CBI, meaning that the woman may be in danger. They track her location using her own bug (which Jane planted on her as she left them) and when they arrive at her home, she is fatally wounded. Jane asks her who attacked her and she tells him that her attacker (Red John, presumably) had a tattoo of three dots on his left arm.
122	6	"Fire and Brimstone"	John F. Showalter	Ken Woodruff	November 3, 2013[n 1]	4X5606	8.46[14]
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 finally revealing the serial killer's 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 beach side while en route to the rendezvous with the suspects at his family home) commandeers a car to arrive at Jane's house, and just as she is about to enter, an explosion occurs, throwing her back. The fate of Jane and the Red John suspects is unknown.

Jane figures out how Red John faked his death in the bombing, which Red John confirms, but there is no explanation for how Red John obtained the list of suspects. Jane doesn't know but recognizes it as "a good trick." Jane shoots Red John with a hidden gun and chases him, finally choking him to death in a park. Jane then leaves a message for Lisbon telling her that its finally over and that Red John is dead.
125	9	"My Blue Heaven"	Simon Baker	Tom Szentgyorgyi	December 1, 2013	4X5609	9.58[17]
Two years have passed since the events of 'Red John', and Patrick Jane — who's been living on an island from which he cannot be extradited — receives a job offer; all criminal charges against him will be dropped if he agrees to work as a consultant for the FBI. Patrick eventually decides to accept, but only on his own terms, which include working with Teresa Lisbon (who is now a police chief). Once Jane's back in the US, Agent Abbott says that Jane will work for the Bureau under the Bureau's terms and claims that Jane's 4-point agreement, signed on the island, has no legal weight.
