I'm not sure if this has been mentioned before but did anyone notice a HUGE clue at Lorelei's death scene?  I missed it the first time too but last night it nearly smacked me in the face!!!

As Jane and Lisbon are walking up to the area where Lorelei was found...what do they walk past?  Old CARNIVAL equipment!  Carousel horses, posters, tents... I also believe Lorelei was lying on top of what looked to be a stage that's used in side shows with a canvas-y type of drape around her.

Forgive me if this was brought up before or mentioned in an episode following but I seemed to have missed it.  I do know that there is an episode regarding PJ's time in the carnival and how a "happy memory" was taken from him by Red John but I don't remember it having anything to do with Lorelei's death.  Maybe, just maybe this is a clue?

I definitely think Jane's past has SO MUCH MORE DO WITH THIS!!!!
