So this is it the grand finale....
I think Jane being Red John is our last hope at a great ending.

Jane is a master manipulator and has gotten away with murder twice.
I think he even hypnotized Abbot into forgetting about the Ba Usb.
Remember that was what Abbot wanted from Jane and i also i remember Jane always tapping Abbot on the arm just like he does to hypnotize people....

What if all that Haibach stuff was Jane?
The cbi Hitlist and murder of Ardilles and La Roche was NOT done by Haibach.
And if you remember Jane was jeleous Lisbon was with Ardilles and Jane also told Rigsby and Van Pelt to include La Roche bc he owed Jane a favor...

-fast forward to now.
Wiley gets hit and remembers old beer. How can someone smell like old beer by just being in a brewery for a moment?
Jane was drunk that night and alone....

Maybe Bosco whispered to Jane "i know its you".....
