RECONSIDERING MY THEORY 

* Kirkland is not for sure RJ...more like a RJ follower.....Lorelei told PJ that he and RJ shook hands but they never became friends....Kirkland and PJ didnt even had the time do became "friends" because he had shaken his hand one episode before Lorelei said that, and one more thing is lorelei couldnt know if Pj and Kirkland did even shake their hands

*Bret Stiles....i couldnt imagine him as RJ because it would be too obvious because of all we know about him, and he is not matching Rosalinds description (and i cant even imagine him and Rosalind togather..i mean she is blind but definitely knows what an old mans face is like), i couldnt imagine him also killing those kids, his voice doesnt fit and i couldnt imagine him helping Patrick bail  Lorelei out of jail- if RJ.

*Gale Bertram...lame at poker, only if not pretending or something, 

*Sheriff Thomas McAllister..Jane tricked him in Rock, Paper and Scissors game...somewhere i read he will be back in season 6 second episode Red-Winged Blackbird...he was easily  tricked by Jane, but somehow all RJ friends were sheriff s or something like that by now... maybe he let to be tricked by Jane and when he was going with Van Pelt he was looking as a maniac to me.

*Brett P....when Pj and BP first met, PJ didnt gave him some big attention...he says he is a ghoul enyoying his work too much...and that he someword him...something like irritates him...also Brett told that he sees the smiley in blood for the first time for real...or something like that...and Jane insulted him but stayed alive...doesnt look so inteligent to me as Patrick but could act the character of BP in the way he does...he could be RJ....and the voices fit...

*Ray Haffner....well maybe he is RJ, to shock us all at the end...and he and PJ were never friends, the age fits, Visualize member (he doesnt have to be on a high place in Visualize, but he can influence on Stiles )

*Reede Smith...HE AND PJ NEVER HAD THE HAND SHAKE! He  is a guest character appearing only in the Season Five premiere so far. Also it's been noticed that his name could be derived from 'Reed' which also means 'Red'. It has also been found that Reede Smith is an anagram for: "the red is me" and "theme is red", which would be fitting were Reede Smith to be revealed as the infamous Red John...also he and PJ were never friends...he most common translation of Tagliaferro is iron-cutter, word to word it would be cut-iron (Cutiron).But another translation of Tagliaferro is ... smith, so Roy Tagliaferro could be translated in english into Red Smith. All this could tell us that by name he could be RJ....but thats too lame to me

So my favourite suspects are bolded out....

WHAT DO YOU THINK?
