This is my theory based on some facts that I will quote below .

Ron is always in the middle of the group of Lisbon / Jane listening to
the conversations, going unnoticed , as in the following pictures ...

 but even there we can not conclude anything , now I'll post 5 important
points to think about Ron.

1 - Look at this picture of Ron clapping ( https://lh6.googleusercontent.com/-wwULfOeUIbE/Uop-9um1H-I/AAAAAAAAB20/Lv9nVnVWmmo/s496/e.png ), is the ep . 1x10 .

when Alex Nelson is invited to speak at the annual neuroscience
symposium .

Who was this ep ? Dr. Miller , who "cured " Patrick after the
murder of his family

 



2 - In ep 2x7 Rebecca (which belongs to the group of Red John ) delivers
a folder pro bosco , when she leaves the room , she is waiting for Ron . In the
next ep staff bosco was murdered .

 



3 - When Red John 's CBI invades the system and send message pro Jane ,
Van Pelt says, " only someone here inside the building can access our
system "

 



4 - This photo below is Ron 's hand , and has a ring that is is the same
ring that shows the hand of Red John when he is drinking tea at the home of the
blind , Rosalind

5 - In the scene that disappears Krystina Frye , who is watching the
door is Ron
