This is not a theory but i just noticed something strange about the Finale:

Agent Rick Tork (Richard Tork) who only appeared in a small role in Season 4 Episode 2 "Little Red Book" when he was as a part of Haffner's Team.

-Why was he given a prominent Role in the Finale?
-he practically came out of no where 
-any one could have played his role, even Cho could have done his parts 
- he manipulated the Team "including Jane" to pretend to be psychic again to catch Lazarus 
-the way he said "the Wife and Kid thing"
-he also manipulated Abbot and Cho to use the wedding as a trap,
-he seemed really smart
- he has a certain look with slightly red hair kinda like Timothy carter 
-there was a really creepy vibe about him every time the Camera focuses on him
and ya he did shake Jane's Hand when he first met him in Season 4 

I noticed all that while watching the Finale and had a slight hope that Bruno could fix his mistakes before the end, but at the end nothing happened :(

why do you think Bruno gave him such a role in the Finale, is it possible Bruno was trying to Screw with us "RJ Fans" ? the Whole Rick Tork thing just didnt make since to me !!!
