Why Partridge's last words were "Tyger, tyger" instead of just saying sheriff's name? Before he died he switched McAllister's DNA records to a random body and he should've known then that McAllister is probably RJ, and not to mention he probably did see who killed him. I don't know, I got the impression, when he was saying his last words, that he wanted to help and I think he could have done more if he just said ''sheriff".
It's also puzzling why Teresa was left alive. If Red John was in that room as well, he MUST have overheard Partridge's last words to Teresa, so why he didn't kill her then? I mean, those words, or actually anything that Partridge might have told Teresa, were a risk for RJ, so why he didn't kill her?
Only thing that can make sense to me is that Partridge, if he were RJ, eliminated himself by faking his death and let Teresa live to pass those words to PJ so they could destroy the organization.
Also, Kira Tinsley must have had x-ray vision.
