Well, I knew Rip and Beth were never getting married, but I thought Rip would be the goner, not Beth.
I wonder if all of those incidents were planned by different people. Beth's bomb could have been ME, John's drive by shooting could have been set up by Jaime, and Kayce could have been a revenge hit by the family of the cattle rustlers. The suffering horse could have been an opening move by Rainwater. Or it could all have been ME, I guess, their "Yemen" solution.
I agree with whoever said Rainwater can't take on the US government and win. He might kill all the Duttons but that doesn't mean the tribe could get and keep the Yellowstone land.
