NEW PROMO!!! ***SPOILER ALERT***
No Theory...Just watch.
Among new footage In the video..if it isn't clear..
Patrick walks into a room (a setup most likely) with Van Pelt and Rigsby, Van Pelt asks him what the plan is..Patrick tells her to shoot anyone that tries to harm him.
Also Lisbon telling someone about the SEVEN SUSPECTS OVER THE PHONE(Really??) and Patrick warning her that Red John will lead her on and get to her!!
And The most shocking part
********MAJOR SPOILERS DO NOT READ FROM HERE IF YOU DON'T WANT TO KNOW********





Red John has completely broken into The CBI and we can see his trademark smiley all over the CBI HQ, with Lisbon and Rogsby watching over smiley's painted on the floor and other places, while two people can be visible in the background, shot and possibly killed.
One is a girl leaning against the wall in the far background and one person fallen to the far right.
BADASS. I'm dying of excitement. Its gonna be AN AWESOME SEASON. CAN'T WAIT!!
