The twin revelation was rather intriguing. I've been waiting for an evil twin and couldn't decide if it would be a 'Jane' twin or another. It throws open a few new ideas.....

Take a good look at the 'woman' feeding the pigeons on the park bench. 'She' is a Kirkland in drag - eyebrows, bone structure, forehead.....

Mike Kirkland, the twin - aka Red John.

It is also Mike Kirkland who kills Lennon in the hospital, not Bob. That is why there was no question about 'who' red John is, Mike didn't need to ask that question.  As for the 'Do you know me' question and the 'No' answer from Lennon - that was RJ's test, to ensure Lennon was still 'hypnotised' (like ALL his other minions) and that he hadn't revealed anything of importance to Lorelei, Jane or anyone else. Hypnosis 101. (RJ would ensure that his minions NEVER remember seeing him in his 'real' persona - possibly only 1 or 2 of his most trusted generals - also hypnotised though. In fact 9/10 of RJ's 'people' would have no clue what he looked like or sounded like and they wouldn't be able to identify him for toffee.

The comment to Lennon about 'hoping a friend would do this for me' - that's Mike/RJ basically saying to Lennon, 'you've been a good servant, but now you die - you're a loose end'.

And the ultimate Mike Kirkland/RJ gesture comes when Patrick arrives at the hospital to see Lennon. 'Mike' Kirkland tells Patrick that Lennon said nothing, then he starts walking away, but half stops, then takes his right hand and pats Jane on the left shoulder in a 'sympathetic' manner. Very similar to RJ patting PJ on that same left shoulder a few seasons back.

Bob Kirkland was almost 95% sure his twin was RJ, which is why he was so intent on keeping up with Jane's investigation - because however evil his brother - blood is blood: and he wanted to protect him. If Jane had got too close to exposing Mike - Bob would have 'sorted it'. 

The 5% doubt Bob had as to whether his twin was indeed RJ or not, is the reason behind Bob going after the others. He wanted to interrogate them himself, and cross them off 'Jane's list' (fake) until he knew for SURE 100%, no 5% doubt that his twin was the undisputed Red John champion of the world.

Have to think about the rest.....where the carnival fits in....etc.

Maybe more twins and lots of questions about paternity......
