We've heard Red John's voice before and it doesn't match up with any of the suspects. How will the show resolve this?
Woodruff: We definitely will deal with that, and I think it's done in a really, really great way that's going to be coming up in [Episode 8]. ... We were very aware of that and conscious of it going forward and in dealing with Red John and [his] voice and all that stuff. So it definitely pays off, and faithful viewers will, I think, be satisfied by it.

I think they're actually saying "In your face Partridge-sounding-like-Red-John believers!" (Or maybe it's just a mislead?). Even though by the end of season 05, I had already made up my mind on Partridge being RJ for different reasons, now I think he's really dead. So I go all-in with Haffner.

I hope they give us a damn good explanation with the voice!
