After re-watching the season 2 finale, the last thing Rj says to Jane before leaving is "roll tide"
This is what the waiter said to Kristina Frye in an earlier scene. Here is the link:

"Roll Tide" is the rallying cry for the Alabama crimson tide which is the collective name for University of Alabama's varsity sports teams.

Now, lets think about which one of our 6 suspects is also a former athlete?

The only one is Ray Haffner as he was a former football player and he even has an award in his office!!! I wouldn't be surprised if he was an Alabama alumni...

It seems unusual to me that RJ would say something random like "roll tide" to Jane unless of course he also had a connection to "roll tide" which I just pointed out above.

Haffner also has the charasteristics of being RJ since:
He is a visualize member
He is a good talker and is charming
He is good at surveillance techniques and is a former CBI agent which explains why it has been so difficult to track RJ
He also seems to have feelings for Lisbon which would explain why he hasn't harmed her yet/

PLEASE LET ME KNOW WHAT YOU THINK AND COMMENT BELOW!!!!!!!
