Guys guys guys...
Don't make me confused with all those Michael Kirkland theories..
My mind is actually believing a little that Michael Kirkland was the one killing Jason Lennon. He did asked do you recognize me? Whether Jason saw his brother or not. Jason didn't see Bob Kirkland, so Michael was free to kill him without a risk.

Please please, don't tell me this..
The guy on the promo is really Sheriff Thomas McAllister, I did prove that with a screen capture in my previous theory. His stuntman also said that he will star on the next episode.

I will get crazy if he is like Bertram also a Red Herring made by Bruno Heller. It would make it totally correct why Bertram took Thomas' stuff, they are working together. Hence the three dots.

What if the Red Herrings (Bertram and McAllister) are getting shot the next episode. And Michael walks in the church and says "The game's over and I won."

I'm getting confused big time, I'm yet still going for Sheriff Thomas McAllister, but this just blew my mind and now there is growing doubt in me..
