Factual error: The container for the dangerous biological material is marked "Biohazard Level 5." There is no level 5. According to CDC regulations Biohazardous materials are rated 1 through 4. Based on the description of the material in the episode, it would be required to be stored in a laboratory rated at Biosafety Level (BSL) 4. All BSL 4 labs require personnel to wear a fully enclosed, pressurized suit when inside the lab. (00:01:05)

Starring: Robin Tunney, Simon Baker, Owain Yeoman, Tim Kang
Green Thumb - S6-E10
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.
Patrick Jane: Don't worry.
Teresa Lisbon: Don't worry about what?
Patrick Jane: You're worried that I'm gonna be upset because you invited your brothers to our marriage.
Teresa Lisbon: How did you know that?
Patrick Jane: When we're married, you think you might stop asking that question?
Trivia: At the time the episode was shooting, Lucy Davis, who plays the victim's widow, was married to Owain Yeoman.
