I saw something very interesting on the latest episode.
1.-Notice in the dream secuence how they are holding the knife.
     a.) Reid Smith Uses The left Arm
     b.)Gale Bertram Uses His left arm.
     c.)Ray Haffner Uses His Right Arm When He Strikes Teresa
         With The Knife.
     Right Before He Painted Teresa's face Rj Was Holding It
     With his left hand.when he killed the girl filmaker he used his left arm
     to hold and swing the knife.My point is i don't think Ray is Rj.
2.-Notice how Rigsby for a split second he looks up at lisbon when he is supposed to be dead...weird unless teresa suspects wayne somehow
3.-If in fact Rj is afraid of heights.....the pigeons or birds might be the hidden clue
     from the last scene in episode 1 and again in episode 2.
4.It is very obvious they are going out of their way to make certain suspects more
   suspicious....when is more obvious that they are working for Rj.

From the list i think Rj Is a.)Bret Stiles  b.)Gale Bertram
outside of the list a.)Walter Mashburn b.)Wayne Rigsby
