I think Theory #10369 may have hit the nailhead pointing out that while Brett Partridge will appear in 6x08, Bob Kirkland won't.
Call me crazy, but this can be too good or too bad for the show. On one hand, and just as 10369 says, it could mean that RJ is Partridge, which by now and sadly is a serious possibility, On the other hand, Partridge could participate in a flashback, most surely in red John's flashback / confession, when he says why or how the forensics guy got killed
So, I think this is very, very important: If Partridge will appear in RJ's confession flashback and Kirkland won't, this can only mean that Kirkland's death wasn't on RJ's account, a definitive proof that tyger tyger and red john are not the exact same thing..
