Think for a second, look where PJ is investigating: open windows, on an easly climbed roof.

whole season we see him being sneaky and closing his door making sure no one can enter (yeah right with an easy lock)

he is fake investigating, he is playing red john again like he did when he 'gave up' and left the CBI being a drunk.

think about that whats more surprising then playing the same trick that didnt work? he would never guess he will play the same trick again.

What u think?
