**Any hints about who survives the explosion on The Mentalist? — Eric
ADAM:
Spoiler alert: Jane lives! In all seriousness, the blast does take out a
significant number of Red John suspects, and before Sunday's episode is
over, Jane and Lisbon will go public with who they believe to be the
serial killer. But it can't be that easy. And of course, it won't be:
Look for Rockmond Dunbar to make his first appearance in the episode's waning moments. (Hint: He's not there to make friends.)

**Question: Purdy, purdy please any scoop on The Mentalist. —Erin

Ausiello: If you thought, as some did (I’m looking at you,
Mitovich!), that last week’s episode-ending explosion was some sort of
neatly orchestrated diversion technique, oh how wrong you are. No, as
this coming Sunday’s episode opens, there are bodies (and, gulp, body
parts) to be found, while a frantic Lisbon places her trust in perhaps
the worst person possible.

So, from the spoilers we can come to these conclusions:
1) The explosion wasn't planned by Jane. Probably RJ or his accomplice(s) did that.
2) Some of the suspects died. In this respect, tthe promo of 6x07 is very important IMO because on the board, we see Stiles, Haffner and Sheriff McAllister. According to this; there are two options:
A) They are the dead ones whose bodies were identified.
B) They are the ones who are missing or at large.
In this case we have two groups and if we can rule out one group, we'll go one step further: Stiles, Haffner and Sheriff McAllister  /  Smith, Bertram. I believe the ones on the board are dead.  I reall don't want that. The first group has more good candidates for RJ so I hope the board contains the ones who are at large or missing.

3) The person whom Lisbon trusts is most probably from "Tyger Tyger" and this could mess up a lot of things.

4)The press conference is interesting because according to the 6x07 promo, I presumed that it would be in the middle of the episode and the last scene would be the last scene of the promo 6x07 (surrounding the house)..So, I'm really curious about the last scene of 6x07 and I believe that RJ's identity will be explained in the last scene.
