I don't think Tyler wants Brett anywhere near the endgame though, and I don't quite understand why as I don't think he is particularly good. His social game is one of the worst in the house. Tyler would absolutely crush him in a jury vote. But that's neither here nor there. I'd be willing to wager that Brett is the next Level 6er that gets let go, but ideally not for a few more weeks.
If Scottie wins HOH I'd be shocked if he didn't take another shot at Brett, regardless how he's behaving right now towards Tyler.
The more intriguing thing for me is if/when Tyler realizes he can't control JC any longer.
