Some thoughts, mostly about S06E01.
1) If you re-watch the first four minutes of S05E22, you'll see a very interesting scene including Jane meeting Partridge. Could be a false conclusion, but Jane's reaction to Partridge points that he suspects Brett (as RJ or as an assistant). So, I think, Jane believes his list is true.
2) In S06E01, when Jane calls Lisbon, she says "Not now, Jane" (sitting in the office and watching the map with seven markers). Why? What was she busy with? Waiting for something? Just a moment later she gladly answers her office phone.
3) A very interesting picture on GPS mobile tracker. Kirkland's phone is in Los Angeles, S1 is in San Francisco (Stiles or Smith), Haffner and S2 are somewhere near Sacramento, but not in the city, the same for McAllister (but not in Napa, strangely), and only Bertram and Partridge are in Sacramento. Just let's remember this for further observations.
4) Don't think it's important, but wasn't Lisbon right-handed? In S06E01 she holds the gun with her left hand.
5) What was wrong with bathroom? Lisbon and Partridge were not alone in the house.
6) Ron's strange appearance means that we should consider some personalities not included in the list as RJ or his assistants.
7) We clearly see RJ talking to PJ and at the same time holding the "knife" in the left and cleaning it by the right. Believing that a human being, even RJ, couldn't have three hands, either RJ uses some kind of earphone, or we are dealing with two persons.
8) I can't believe we'll be informed about RJ's identity in S06E08. I'm not a fan of kind of "he is many" theories, but unfortunately we are directed in that way. So probably only one important name would be revealed in S06E08.
