Just some thoughts to share ...

In the first episode of Season 6, when RJ's knife is shown up close, when I first saw it, I thought it reminded me of something, but I could not quite place what it was.  Finally, after pausing the scene, it hit me ... the knife resembles the head of a bird.
 
I found this to be especially interesting, because there are so many references to pigeons in all of the episodes (the pigeons flying out of the room, in the first episode / the women feeding the pigeons in the second episode ... by the way, she was very big for a woman, had red hair, and a large ring ... I personally thought she looked suspicious ... really a man ... listening to Jane and Lisbon's conversation? / .... and then, in the 3rd episode, there was the pigeon flying at Sheriff McAllister).  I cannot quite make the connection of the birds, but somehow they are very significant.  And of course, it is obvious that pigeons and partridges strongly resemble one another.  To some, this might mean that Partridge isn't really dead or that perhaps RJ has a phobia of pigeons.  These could possibly be theories, but it is also possible they mean something else entirely, that the audience simply does not know yet.  Oh, by the way ... Didn't we also see pigeons flying out of the Red Barn in that episode?

I have not been one to think Partridge is alive, but yet, it isn't impossible, given everything we have seen.  In this regard, one thing that is noteworthy is the fact that we do not actually see Partridges' dead body, nor do we see the team attend the funeral, which seems quite unusual, given all of the funerals we have seen them attend.  Also, of interest is Blake's painting "A Brace of Partridge," in that Brace's poem "Tyger Tyger" has been quoted by RJ and his followers.

No matter who RJ turns out to be, I believe Heller will give his audience a lot of drama/intrigue when RJ is finally revealed.  I have no doubt that that there will be many connections revealed, that are not apparent just yet.
