First of all I'm not sure who red john is .I had great theories but now...

Jane's narrow down the list of seven Red John suspects
I still can't understand how jane could possibly know where everyone could be in the time of RJ's murders.( he knew where mashburn or others were ? )

Fake list . 
I read somewhere that Jane reveals that a list of fake Red John suspects he planted was stolen, and the team realizes these men are in danger, so 7 suspects are fake or what?

whistling :
Like last season's handshake. Now suddenly people in show start whistling.

show's Orientation :
In this season they trying to make bertram and haffner look like the main suspects . bertram's dialog in first episode and haffner in second !

Bad feeling :
honestly I am feeling stupid for spend so many hours to watch and analyzing clues .

I Just hope they have a strong explanation about everything .

Thanks for you time and sorry for my bad english
