In my mind there is a high probablilty the "He is mar" clue is a fake. Here is the reasoning:

Renfrew is supposed to have his infos about RJ trough Orville Tanner. In S01E11 Van Pelt alleges that they were cellmate 7 years ago. Now what time is seven years ago?


Jane
and Van Pelt meet for the first time in the pilot so any episode
including Van Pelt must be later than that. We also get a glimpse of Wagners patient calender for Alison
Price. It has entries for 08 so we are at least in that year. Even if we disregard the entry in the calender, there is another exact
point in time. In S01E10 when Jane picks up the call of sophie miller
the date reads 08/28/08.

Since it is Van Pelt reading the info about Tanner and Renfrew we can't be earlier than 2008, therefore the seven year reference can only mean 2001.

S01E23 delivers an other pretty accurate point in time. When Chow and Rigsby question the store owner who sold the elephant they mention Thanksgiving last year and that it lies 5 months in the past. The security tape is stamped 11/27/08, therfore S01E23 happens around April-May 2009.

At the end of the season finale Dumar asks Jane if he knows who Orville Tanner is. Jane replies that Orvilles was an accomplice of Red John who got caught and died in prison 10 years ago. Dumar confirms that.

It is 2009 so Orville died 1999 in prison. It is therefore impossible he could have shared a cell with Renfrew in 2001. It is further impossible in 2001 to share infos about a murder taking place 2003.

Just finished watching "White Lines."  Here are some random thoughts.

-that episode is really different from most episodes, even since the "new beginning"

-the whole killing red john & wedding ring thing just lingers and lingers.  Like they bring it up but its unresolved.

-the lady Jane is on a date with says she understands why he still wears his ring.  Am I missing something?  To me it is counter-intuitive!  I thought he would stop wearing his ring after killing McAllister.  That could be a clue if you still believe RJ is alive.  Like Jane knows it or something.

-abbot is only shown for a few seconds if i remember correctly

-now more than ever, i believe something will be revealed about fisher's past

-and in the promo for next weeks episode, Cho says Jane is being crazy like the first few years in the CBI... hmmm

Some questions and other things.

In my mind, if the BA is still around (which it is), wouldn't they want to hunt down PJ? He did however tell the world about them and he killed RJ (I doubt sheriff is RJ).

How did RJ stay so strong for that long? How did he figure out about everything about PJ (ie. The memory, list,etc.)

Was LaRoche part of the BA? We know he had a big secret (the tongue), so he could possibly be part of it.
Other things:

Patrick makes up a FAKE LIST of agents part of the BA. Emphasis on the FAKJE LIST. This could mean he's made fake lists before -hint hint-

Where can the show really go on from here? You wouldn't end the main story mid season for no reason, something is going to happen, and it might happen next episode (Rigsby and Van Pelt are said to reveal something shocking next episode. Possibly RJ killing someone? Hightower or even LaRoche?)

My guess is that next episode is going to be BIG, and the hunt for RJ will continue. I also believe the Jisbon story line will continue, but I'm not really a fan of it anways
