For all those questioning why Bob Kirkland didn't ask Lennon about Red John.
1. It was Mike Kirkland in the hospital room with Lennon.
2. He went there simply to 'kill' a loose end FOR Red John, as he is obviously a 'RJ disciple' doing RJ's bidding. He didn't need to ask where RJ was or who he is, simply because he knows already and was there on RJ's behalf.
3. Listen carefully to the conversation between Lennon and Mike Kirkland: especially where Kirkland says 'your mind is clear'. That's hypnotism right there.
4.Trigger words all over that conversation.

Mike Kirkland is not RJ, but he sure is a friend of RJ's.
