I was going with Sheriff from the start and I'm going to stick to it.

Out of everybody that presumably died, it's the Sheriff that would make the most sense to come back. Clearly, Smith and Bertram aren't RJ. Patrick wouldn't tell everybody the name, because he wants RJ for himself.

So, it has to be someone who is dead. I'm going to say McAllister actually makes the most sense, not only because he is my choice from the beggining, but there are a lot of other things that have already been explained.

The thing that caught my attention is the calmness when he is sitting. I don't know how to explain why he said that he isn't RJ when Patrick pointed the gun at him in the previous episode. But that was probably just a act, because he knew Patrick didn't expect to see 3 people with the tattoo.

What caught my attention from the start and especially in the Red Wedding episode was his incredibly good sense of smell. We can still remember the Strawberrys and Cream episode, where Timothy Carter, a.k.a. Fake Red John, told Patrick how his wife and daughter smelled before he killed them. Nobody has such a good sense of smell and that that was included wasn't a coincidence.

I still don't know how to connect him to Visualize. And I'm not sure how would he attract women, much younger than him, especially Lorelei, who is a hottie.
