If you look at this game from just Spencer's perspective, he has been on an up and down roller-coaster about as much as any other contestant ever. Every week it seems he goes from the bottom, to the top, back to the bottom. He must be a wreck mentally.
When they had their 6 vs 5 tribes, and knew the merge was imminent... the move to do is to back your promises, with the collective promise that if anyone flips, NOBODY will give that person jury votes. That is 5 votes guaranteed not to go to anyone flipping and essentially kills any chance they have to win. It has to be understood that flipping is a death sentence, but people never seem to leverage their jury votes.
Hard to believe that Trish and Tony have been the most influential people in the game to this point. Tony behind the scenes and in challenges. Trish by orchestrating the ousting of Cliff and Dreadlocks, and then flipping Cass to Sarah's demise.
I suspect Spencer's crew will start to cannibalize one another now, and Tony's alliance will destroy them one by one. Please god, let Morgan be the last to go.
