Are we supposed to believe that the Sheriff is Red John when the Sheriff could not even play rock, paper, scissors with Jane in season one???
Its Rigsby!
We have to remember that Red John gives people what they want most, and that is how he ensnares them. We all saw Rigsby give the lawyer lady a baby that she really wanted, right? Miss lonely hearts will be back, methinks.
Lastly, why show conflict between Rigsby and the smoking hot Van Pelt whist arrested in the backseat? Why is Rigsby such a Clark Kent all the time? The dude is a serial killer!!!
