Not a theory. Just two clues for the "Lisbon is bugged" theory: i don't know if someone already noticed but i was re-watching the last episode of season 5, and two strange coincidences came up. When speaking about happy memoris, Jane having one about Eyleen Turner, Lisbon says her happy memory links a song to "her mother feeding pidgeons" (the famous SE06E02 scene). Plus, Sean Barlow plays the psychic with Lisbon, guessing that her father was an alcoholic. No guess, Red John told him. The two have been in contact: maybe just for that murder, maybe Red John was some guy in the carnival ("he's been there from the beginning", BH). 
Anyway, it makes sense that PJ has a strategy, knows that Lisbon is bugged and has exploited that for some time now. This is how is going to catch RJ.
