Well, it's not a theory. More like a thought. I believe there has to be some sort of connection between Smith (a known member of TT) asking "Exactly how much does Jane know?"  in 6.02 and the PI saying that her client wanted to know everything Jane and the team knew (6,05), That kinda implies that RJ didn't hire the PI but the "Tigers" did.

Also, as some people have stated, it's never been a problem for RJ to be aware of Jane's and Lisbon's plans.

With hindsight I felt disappointed because Patrick Jane did not take into account that there could be more than one guy with the same tattoo.

But then I humbly realized nobody in this forum - including me - thought of that possibility either (at least as far as I could see).

So, let's see if we can do better this time, with predicting the possibilities about what happened in that room at the end of the previous episode... or will the writers surprise us again?

We can assume Jane is not dead, because if he was dead, likewise for the series.

I also assume it was Jane's shotgun that went off, because of something I read somewhere from one of the writers who said that 'that shotgun did go off'.  Also, it was a big noise and a huge flash, so it didn't look like a handgun to me.  

I assume that it was Jane who pulled the trigger, but I must also assume that Jane did not kill anyone or else he would be locked up for the remaining episodes and won't take further part in the investigation.  By the same reasoning he couldn't have planted the bomb, because I also assume the bomb in the room killed some people.

The question is why did he pull the trigger.  Did somebody try to take the gun away from him?  But who cried out "Wait...No!" just before the shot?

My prediction is it was either Haffner or Stiles who tried to pick up a gun while Jane was busy with the dot-guys, and possibly aimed it at Jane, and Jane swung round and said "wait..no!" and then had to pull the trigger, but probably aimed over their heads.  Why do I think this?  From the outside Haffner and Stiles would be sitting on the LEFT of the door, opposite to the wall where McAllister, Smith and Betram were being lined up.  And the LEFT window is the the window that lit up when the shot was fired.

I predict that at least two of the guys with the dots on their shoulders are still alive, because we still have to guess who Red John is for an episode or two.  This also means that whatever happened in the room just before the bomb blast did not identify Red John conclusively.

Jane and the CBI would make damn sure the dead guys are really dead - so hopefully, no more "whatsisname is still alive" theories when we know who they are :)  

McAllister, Bertram or Reede.  At most, one of them died.

I think Red John IS one of those three guys, and must have planted the bomb to make sure he had some kind of diversion when the meeting with Jane proved too hot for him too handle.

The only problem I have with that is how did RJ make sure he didn't get blown up too.

Another theory is that Michael Kirkland, Bob's twin brother, figured out where Red John would be and planted this bomb to kill him, not caring who else got hurt too.

And of course, many people would also say, RJ is not on the list, and he planted the bomb to take care of all his problems in one go.  This I don't want to believe...

I just hope that atleast Reede Smith is not Red John. He does not fit any criteria and the guy who was in Harker's home was thin, even his fingers were thin. Still in the ending, if they portray Reede Smith as Red John, then this will be the worst series ever on TV. All the clues thrown at us were fake. I think it might be Bertram. Remember Red John told that he found out when his good friend in the FBI found out. Both Smith and Bertram are in Tiger Tiger group. And looking at how things might turn out, Bertram might be revealed as Red John, so in a sense all the clues still stick together and yet the fans will be disappointed. I don't see any reason why Reede Smith would be Red John. He wasn't there from the beginning. Only Mcallister was. So the entire logic has been thrown out of the window by Bruno Heller. The reason why nobody is able to predict who Red John is exactly is because everyone is trying to use logic whereas Heller does not have one logical theory. So whatever you do, in the end I just hope that it is not Reede Smith.

The three remaining suspects are apparently Smith, Bertram and McCallister. This is why it is NOT one of these three.

Smith- Clearly doesn't match Rosalind and the psychiatrists description. He also appears sloppish, afraid and often unsure of himself. Red John would definitely NOT be him. When he was asked to show his arm to reveal his tattoo, he looked scared. He also tried pulling out his gun clumsily, which Red John would never do. Saying he is afraid of heights SO OPENLY is a dead giveaway he is NOT RJ.

Bertram- Bertram is always "reporting" to someone on the phone. He seems overly-curious about Red John as well.

McCalliser- explicitly tells Jane "I am not red John"- something RJ would NEVER EVER EVER DO. Also appears much older than the desc of RJ.

The producers would naturally want to shove us off a little... So that's why they're putting the focus on these 3. Back in episode 2, the same 3 met at Bertram's office to discuss matters. None of them are really Red John.

Based on the descriptions of RJ in the past, I would say it is most certainly Ray. He is very clever and resourceful, could have removed the tattoo if RJ was truly the one who killed Kira Tinsley OR one of those three killed Kira Tinsley because they wanted to bug CBI and knew Jane was on his way there. PS*** The murder of Tinsley was also sloppy and hurried, with no trademark SMILEY RJ normally leaves behind....

Am I the only one that noticed that Reede Smith, (who works for the FBI), didn't care one bit that Bret Stiles was right next to him.

Aight guys my theory:
We've waited all almost 6 Years to this moment, come on heller is for sure doing a great thing to entertain us so stop saying partridge is not dead or something like this, this would be a MISERABLE ending.

Let's look closer to the details.

I also recognized the coffee thing. Ray got black coffee when he met Teresa and in this scene you have to look closer at Teresa. When the coffee was served she takes a look to the bar or to some people out there. I'm sure the coffee thing is very important here but i can't tell what exactly.

I'm also almost a 100% sure that RJ has NOTHING to do with the tyger tyger group which has the three dots and the tyger tyger password, except that he knows them. Maybe RJ just want's to fool Patrick here and want's to lead him to a false trace which would explain the scene when RJ saved Jane from the kids and ended his act with the poem tyger tyger.

Michael Kirkland will show up for sure. The tyger tyger group will be excluded from the suspects. (McAllister, Smith and Bertram). So there are 2 possibilities here: Ray Heffner or Bret Stiles.

I assume it is Ray and i'm as well very sure that this "ecuadorian connection" from Stiles will play a role here.

Cant look forward to the next episode. RJ is not so important anymore. The tyger tyger group will keep the story entertaining, even if RJ is revealed.
