Character mistake: When Kim is trying to convince Lisbon to help the FBI on their case, she says Jane stopped the ten-year reign of a mass murderer. Red John was a serial killer, which, by the FBI's definition, is a criminal behavior distinctly different from mass murder; he may have had a large number of victims, but he killed them either one or a couple at a time, with a cooling-off period in between, not all at once.
Teresa Lisbon: I don't think I've said this. I mean, I know I haven't said this, but I don't really know if I need to, because you always know what I'm thinking.
Patrick Jane: Well, not everything.
Teresa Lisbon: Would you be surprised if I said I love you?
Patrick Jane: I'd be... I'd be lying if didn't say I would be moved by that.
Teresa Lisbon: I love you.
Trivia: The lakeside cabin Jane bought was shot on location at Disney's Golden Oak Ranch. It is called 'Cabin by the Lake'. Http://www.lamag.com/citythinkblog/scene-golden-oak-ranch-mentalist/.
