Thank you for posting your ideas. Because I've been back and forth repeatedly this week. But, I think that I've settled on ... Keith.I do think that - in order to set up the Finale - no matter how the Episode plays out (and there are just too many loose ends yet to be - editorially - tied to know what will happen), this will be the Episode in which we are meant to be persuaded that Tasha has a viable opportunity to win the Game.
And perhaps it will be as simple as Keith attempting to flip to the guys - a move that Tasha would not welcome - that prompts the entire group to vote him out.
Or, perhaps it is Abi-Maria who is once again the swing vote. In the portrait of her in the chair, it looks as though she has struck her Woe is me! I have such an important decision to make! pose.
