I watched the two episodes again and made the following assessment:
Game wise, Jeremy has the best game right now. He made a big move by saving Stephen, and that was supposed to put a target on his back but it didn't. Instead, it helped Tasha and maybe Spencer see that with Stephen now, Jeremy is a loyal person to stay with and good to trust. He has an idol in his pocket, and will most probably not go anywhere.
The second best person with the best game would be Spencer. He has a great r/s with Kelley and Abi. He saved Joe's ass, and he is also in Jeremy, Tasha and Kimmi's loop. He's not going anywhere if you ask me.
Keith isn't going anywhere as well. He's a good person to keep, and to take out at the F4/F5 when everyone started realizing that this chill old man is here, and he has not made anyone angry, and nobody bears grudges with him, and will then be voted off when nobody wants to bring him to the end. This can happen even earlier in the game when they start realizing that Keith is a threat and will swing anywhere as long as it is not him.
Kimmi and Tasha seemed to be having the same game, the game of listening to what Jeremy (and Spencer?) wants to do? They can loop in Keith anytime, then form the majority 5 alliance of Kimmi, Tasha, Jeremy, Spencer and Keith.
Abi and Kelley, although still together, are really still at the bottom of it all. Their only chance is for Spencer and Keith to move, because the gang of Jeremy-Tasha-Kimmi seems not be going anywhere. Joe is their asset as well... But following the anyone but not me Sandra's theory.. I think their best interest is to keep quiet when they realized that Joe is the next target. This voting block thing, essentially, just means two voting blocks merging into one, and still putting Kelley and Abi at the bottom to be honest.
And speaking about Joe, he needs the girls. And anytime he decided to vote out any of Abi or Kelley with Jeremy and gang, his game is over. But he will need to win immunity first, otherwise he's gone next.
Essentially, I think Jeremy has placed himself in such a great position that nobody sees him as a threat and I have no idea how? He's using Stephen as a strategic cover, and Joe as a challenge beast cover. I really am interested how he wants to let his game unfold as he eventually break out from Stephen's strategic cover after he gets voted out, and Joe's challenge beast cover when he gets voted out soon.
TBH, Abi is a great pawn to bring to the final 3 from our viewers perspective, but I think they would have known better that if she's at the bottom and still make it to the end, there's a possibility of the jury being bitter and giving the vote to her.. so I don't think anyone in the right mind to do that.
I believe Jeremy, Tasha, Kimmi and Spencer are in the best position right now (which sucks because my Queen Kelley is in danger) and if any of them were to turn on one another, they would be crazy to do so.
