SPOILER

Bertram rings PJ and asks to meet him. I would suspect this is in the church. and Bertram gives him information which then leads to identifying RJ.  The RJ voice has been dubbed over in the actual preview and comes later.

Watch this.
Not the first part. (that's a 30s preview) Watch it then........

it is a 2nd part press play again  once it has stopped. it last 1m 23 seconds.. kinda tells you what is going on

 I actually thought I had stumbled into the whole episode for a second.

I've been following this site for some time and enjoyed the diversity of ideas and deep knowledge of the episodes. Full credit to BH for upholding the enigma as to RJ's identity through countless misdirects, false dawns, near misses etc. I can honestly say I have no idea what to expect - whether PJ revealing Bertram as RJ is a double bluff (for the audience), and he really is RJ, or if RJ is from the list at all. All I will say is that the ending to Strawberries and Cream from Season 3 was terrific, and I was very disappointed when Timothy Carter was not Red John. If this episode matches that, we're in for quite a ride.

My dear COMRADES

I'd like to spare you from the itchy brain struggle which you're having by thinking who RJ is and relax for a moment for another fun poll. Although, only the ones who also follow "Person of Interest" can contribute here but still it's fun.

So, which one rules when compared?

TT from The Mentalist = GREEN
HR from Person of Interest = RED  

Have fun and if you have anything to say about both, be my guest in the comments section!!!

Red John is Danny Ruskin.

The only problem I've got with McAllister being RJ is the statement he made by the end of 6x06 after his tattoo was revealed. 

"It's not what you think. You got it wrong. I am not Red John"

Well, in my opinion real RJ will never deny his true identity like that, he's too proud of his work, too narcissistic.

Due to the skin removed from Partridge hand (and just so you know i am not Partridge -RJ Fun) It can only means that tattoo wasnt there ... If tattoo was there no need for removal needed , becouse everybody knows about tattoo and his tyger tyger words... The only pissible reason why is skin removed is becouse there is NO tattoo on that body .... To trick anyone who look at it in to tinking ... I am not saying that Partridge is live , and body is replaced .... But i am just saying why skin is removed ....
