Theories of agora2 (4)

Okay,the scene from the past explained is Rebbecas murder(Smith arranged for someone to get in the cbi to kill her)-this also opens question why would Bertram if being Red John try to get someone from the outside in the cbi but that is not my point here...I have two questions and would like to hear Your opinion

1) Who was the person from the past we haven´t seen for a while apparently showing up in this episode(flashback of Bosco?-this just doesn´t fit the announcemenet)

2) Why did Red John kill Partridge,what is the meaning of his skin removed from the shoulder(obviously to hide the tattoo but why?)

Please comment.

From everything I heard from the upcoming episodes,I believe whoever Jane is going to say to the press is Red John probably is not...I think he will mislead Lisbon and everyone else on this one and do this himself.

Does anyone know who is this mysterious young man played by Nick Nordella in upcoming episodes...I have already heard speculations that it is either young Red John or young Patrick Jane...what do you think and was there any official news about this character...he resembles Sheriff Thomas McAllister the most of remaining suspects

I really love theories on this site,they were very few bad theories abouth who Red John is( Van Pelt,Lisbon,Cho,Rigsby,even Jane himself...those were really bad theories) but now I see a whole bunch of Michael Kirkland theories and I am sorry guys but this one beats all of them...it is the worst theory ever,making Red John someone we have heard about until 6x4...come on,if Michael Kirkland would have turned out  to be Red John it would be the stupidest ending of all time...I am really surprised how many fans this so called theory has because I see a lot of plausible hits on that kind of theories.
