I'm still going with McAllister as Red John.
The last episode shortened our suspects pool to just 3. And yes, I believe one of them is Red John. Sheriff has been my pick from the start and I'm sticking to it, eventhough Bertram is getting more and more suspicios.
Here are some of my questions. We heard Jane pulled the trigger. Did he actually shoot someone? Why did the house explode? Was that a plan from Patrick and everyone agreed or what? Who did Bertram call right after Lisbon and Jane gave him information about Red John?
I would count out Smith as RJ, because we saw him reaching for a gun. RJ wouldn't do that at that particular time. He enjoys games with Patrick. He wouldn't want to shoot him after his first threat.
I thought this episode is going to lead us closer to RJ. In a way, it did, but I have to admit, I'm more confused that I was before watching it.
