Ok I havnt seen last nights episode yet, but i want to make a follow up thought on my previous theory.

i think that we have seen michael kirkland at least three times.

I believe that the kirkland we see at the end of red dawn was Michael Kirkland. 

the FBI agent says to him "the work is done" after Jane is accepted on at CBI. Did RJ use connections to get Jane involved at CBI from the very start so that he could play with him? This is a strange comment from Alexa.

the second time we see michael is the handshake with PJ.

the third time we see michael is when he kills jason lennon (not cooper). now this is important. he asks have you seen me before. lennon says no and a look of RELIEF is on kirklands face. Why? because he is red john and lennon is a loose end. 

how come lennon doesn't recognize him if he is red john? same reason accomplices kill themselves after being caught. Red john is either skilled in strong hypnosis or mind control or both.

red john is relieved his accomplice does not recognize him because it means that his identity is safe.

bob kirkland would not look relieved by lennon's answer because he is trying to find red john. therefore this person is not bob, its michael.

micheal kirkland people. michael kirkland
