The Mentalist

The chess game is (ECO A13) English opening, Agincourt variation.

The title, when translated from numbers to letters, spells R-E-D.

When Jane walks into the Draber's warehouse with Lisbon, he is wearing his jacket, then in the container, he isn't wearing it, nor does he carry it out when they walk off with the kid and the goat. Yet when they arrive at the courthouse, he has it with him again.

As Agent Cho is ending his interview with Griffin Wells, he states "You'll be the richest man in Folsom."
Folsom is a prison run by the California Department of Corrections and Rehabilitation in California State. It is located in the city of Folsom, 20 miles (32 km) northeast of the state capital of Sacramento.

When Dr. Seberg finds the opened Cryptohansa B vial she stops Dr. Welks and Harken from opening the door, because she knows the virus must be contained within the chamber. Seberg responds to Jane's question that the killer would have taken the antidote in advance of opening the vial, the only way it will work. Although having taken the antidote protected them, it is never explained how the killer managed to leave the contaminated chamber without releasing the virus.

At the start of the episode, when Cho is given the address of the murder, the line we hear is "1300 Summit Street" while the closed-captioning reads "3700 Heller Way."
Later at the start of Crystal's interrogation, Lisbon's first line is "Where did you get the drugs?" while the closed-captioning reads "We don't really care about the drugs."

The episode's title, "Redline," is an automotive term that refers to the maximum revolutions per minute (RPM) an engine may operate without damage to the engine itself. The tachometer, an instrument resembling a speedometer, shows the engine's RPM and displays the data with a needle and numbers on a dial. Once the engine reaches maximum RPM, the digits are colored red and separated from the safe RPM with a red line.

In the scene where Bosco and the other agents are found, Lisbon goes to Bosco and immediately checks for a pulse. This is the incorrect sequence of steps. The current ABC's of the the American Heart Association are: First, check for open Airway; second, check for Breathing; third, check Circulation(pulse). Not only was Lisbon's pulse check out of sequence, she seems to indicate (barely audible) that Bosco has a pulse then begins to give unnecessary chest compressions on a beating heart. Her attention should have been directed at his airway and breathing since it appeared he wasn't breathing. Even if Bosco had no pulse, the airway and breathing should be checked first.

Rigsby begins to sing Amazing Grace during the toast to Bosco. Amazing Grace was written by John Newton in 1779. Newton's early life was rather sordid as a sailor and captain of slave-trading vessels. It was during a fierce storm at sea on March 10, 1748 that Newton "cried to the Lord" for help. He then began a rather hypocritical journey through Christianity. Newton eventually publicly admitted he was wrong and became a strong force to have slavery abolished in the British Empire.
Traditionally, Amazing Grace is played on the bagpipes at funerals for military and law enforcement personnel.

The placement of the dead doctor with the arrangement of yellow flowers is allegorical in nature. Jane makes the statement that "he was posed like this, not just dumped here willy-nilly." In the floral business, different colors represent different emotions or statements. In this case, the yellow flowers "symbolize new beginnings, happiness and friendship." This is the message that Red John is sending to Jane. In mocking fashion, he is telling Jane that he is looking forward to having Jane back in the chase.

In the security room, when Rigsby puts his hand on Van Pelt's shoulder to comfort her, you can see a wedding band on the right hand ring finger, although he is not married in the show (but is in real life).

Jane and Cho go to retrieve the male murder victim that had been buried in concrete, who was the husband of one of Red John's victims. When they arrive at the morgue, they discover that the body has already been taken by a female CBI agent named Rojo. Rojo is Spanish for "red."

The musical piece that is playing in the doctor's office where Agent Hicks is found is from "Well-Tempered Clavier," Prelude 1 in C major (BWV 846), by Johann Sebastian Bach. In the Season 1 finale, Jane finds out from Rosalind Harker (Alicia Witt), that Red John's favorite composer is Bach, and she plays that piece for Jane on her piano. It is also the background music that is playing in the final scene from Season 1 when Jane plucks the orange from the tree.

In the scene where Van Pelt is in the security office checking the camera footage, right after the security guard leaves the office, you see Van Pelt put her head on her hand, but then the camera view changes and she is sitting up straight as if she never moved.

Red is a predominant color in all episodes of The Mentalist. In the closing scene of "Red Bulls", Jane is seated on the couch reading a red covered book. This is fairly obvious; however, a more subtle allegorical representation of red is the book that the camera pans across just prior to focusing on Jane. The book is Communism and Development by Robert Bideleux. Not only is the cover of the book decorated with a series of red flags with different symbols of communism, but red is also the official color of the Communist Party.

The background music playing while Rigsby and Van Pelt are kissing is the same one used for when they kissed in the Season 1 episode "Russet Potatoes".
