I really feel that this is a total "logical" guess this week.

First of all, I agree with Corvis that it doesn't seem like any of their times to go. However, the press images have never been wrong and since this is a 2 day cycle, I believe the IC was early in the day. When they come back to camp ~1:30 PM according to time stamps, we see Woo bending over to get the fire going. They look miserable. So, I think they are LOSERS.

So, which of the three candidates? Abi is the nemesis to those of us that like to think about the events of the week leading to a logical boot. She is a nightmare. I really feel like it's Varner's turn to go, but he has weaseled out of being the boot several times before and he wants to make it to the merge. From this shot:

...it really looks like the Angkors are in first place as Varner is doing GREAT as the caller. They have more blocks collected then anyone else. If Varner does so well in the challenge, why would they get rid of him?

Abi is a paranoid basket case. Last week Andrew and Tasha needed her more than she needed them. Not so this week. Woo is going to cling to Andrew/Tasha and we know that they value strength. If the tribe loses than why would they vote out their strongest member besides themselves? Woo could be the boot because he did NOT have an intro confessional. But, I think if they get rid of Woo, they will witness their own demise sooner rather than later. So, I am not voting Woo. If Woo is off the table, then it's between Varner and Abi. I noted the case for Varner up above. He's far more rational, he's apologetic and expresses his loyalty. Abi, otoh, is a loose canon, and they must start to see what Spencer saw in that she's a cancer, and deathly to an alliance.

Then, in the challenge we have this picture:

Andrew takes a break and gets crucified by Abi, perhaps? Regardless, I just don't think they need her anymore. Her conflict was resolved when she got them to vote out Pei-Gee. So, I am voting out Abi.

I wouldn't be surprised if it were Varner or Woo either.
