Ugh I am just going crazy with this show. I'm obsessed!
So the house that they are swarming in the S06E07 promo is in Roseland, California (you can see the police cars). Roseland is very close to Napa Valley geographically. Are they at Sheriff McAllister's house? Might be a stretch, as they may just be at another crime scene that they usually have week to week. Although, we've been told (by some of the actors and Heller himself) that the next few weeks will move at a very high-pace plot wise, and so I'm assuming the next episode will only have to do with RJ and the fallout from last week.
Additionally, in the promo, when Rigsby is talking to another agent telling him about RJ and the bomb, we can see (in the HD version) that the board has 3 suspect photos, Haffner, Stiles and McAllister. He looks to them in reference when explaining that RJ apparently brought the bomb to kill 'the suspects.' Since Smith and Bertram are not there, does that mean they are deceased? Also, the diagram on the board has the bomb explosion point marked down, it also has post-its where DNA was found (in 2 places-- maybe more, it was too blurry to see-- that coincide with where Jane had the 5 of them positioned in the room). Interesting to note.
One thing is certain... I spend A LOT of time thinking about this show. Oh boy. I am starting to worry that Heller's version of events to come won't be as fascinating or plausible as some of us have theorized. I really hope that's not the case. I am also expecting full explanations for all the clues that we have been given (for example, the 'he is mar'). Let's cross our fingers that Heller will blow our mind with the episodes to come!
