As per the advanced review clue that a long gone character would make an appearance, here are some people I would love to see make a comeback because they could provide more insight or because their is more about their story I'd love to learn...

Brenda Shettrick-  the dirty reporter who gave intel to Tommy Volker has some 'splaining to do.  Is she really just going to get away with all of it?

Alex Jane- I just want to hear more about Patrick Jane's past, specifically, whatever became of Patrick's mother?  We've never heard anything about her, not even a mention.

Rosalind Harker- you all know you want to hear from her again, especially those of you who recommend she pat down the suspects in a lineup.

Lorelie Martins- I've always suspected she wasn't really dead.  How the body of the supposed Martins was laid out in a carnival scene just screamed red flags!

J.J. LaRoche- he gathered quite a bit of intel while investigating the burning detainee at the CBI, but we never learned what he discovered.  He just disappeared.

Walter Mashburn- so he can be killed off and people stop saying he's Red John.

My own list of  suspects...;)  

1. Danny Ruskin
2. Patrick Jane
3. Virgil Minelli
4. Wayne Rigsby
5. Kimball Cho
6. Elis Mars


1. Someone unespected, has the same voice as RJ if you compare them, carnival days...i could write till morning why...
2. Multiple personality disorder, making fun of the CBI meanwhille killing the Tigers and using the excuse of them being RJ....
3. Powerful man and could be in touch with the Tygers, Bosco died and he disappeared...etc,etc..
4. Wayne...just because he is so damm naive the whole series, he did nothing wrong one single episode...just standing there and being naive and somehow a perfect man...a man that any woman would fell for..., and we dont know much about his past and we do not know why was he divorced with his 1. wife...
5.Cho...just the opposite of Wayne, misterious, not smiling, just standing there, unsuspicious and at first an unsignifficant character, ....there is always a what if question for this man....
6. Just because he is creepy and because of the He is Mar thing....but i dont know...i doubt..

The famous list of 7 is a fraud..so it leads me to 2 possible conclusions...IF...!
1) RJ is PJ he made the list just to catch the Tygers to kill them in excuse (some of them)  being RJ, or RJ disciples....but the real deal why he gathered them was to kill his copycats, 
2) If RJ IS NOT PJ....I  REPEAT...IS NOT PJ!!!
He has to be someone outside the list of 7...definitely!.

STILL THERE IS A BIG QUESTION ABOUT TO BE ANSWERED! Who implanted the bomb there, I think PJ would not be so crazy (IF NOT RJ) to plant a bomb and kill half of the people from the list..including putting the life of his boss, and even LIsbons life at danger because when the bomb went off if she was a little faster she would get in the house and maybe die in the explosion...on the other hand, if it is RJ that planted the bomb....HELLO, now he is blowing up things now including himself ( IF THE LIST IS REAL) ?? Thats lame to me..;) SO AS FOR ME RJ IS SOMEONE NOT FROM THE LIST....

Anyway, I AM NOT SAYING THAT PJ is RJ....but remember, he can manipulate things out just the way he wants, so it will be likely that he manipulated us at one point, just so we can see RJ the way he wants us to see him....at the end i think we will all be manipulated and scratching our heads saying...i  fell for it....just like Lisbon did, Luther did, Laroche did, Rigsby did....and others...

Now that i have seem the previews its apparent that nobody on the list is red john. Like i said earlier , the list is a form of jane playing by red johns rules. Rj is throwing jane a bone about the currupt tiger tiger crew. Patrick knows rj isnt part of them. Pj is playing a dangerous chess game barking up the wrong tree and shaking the branches until all the tiger tiger crew falls out. This will force rj to think he/she is in the clear and thats when pj will have a checkmate . Something is to be said about the lorelie tape. Is she alive ? Maybe . There has to be a reason rj knew the list and that is the only logical explanation. She isnt the typical rj follower . Shes hot. Banged pj. And seems stronger than the other followers who were so weak minded . Van pelt may be rjs daughter or she could just be a weird character . She could also of been a man at one point. I mean why hire a broad shoulders deep voiced red haired woman for the part ? The end is near and i cant wait ! The people
On the list are all but dead and its gamete .

When the 5 suspects are lifting up their shirts, Bret Stiles has SOMETHING on his left shoulder that looks quite a bit like the Red John smiley face.  Take a look at the scene again.  If you use this link...
