Isn't that Brice on the far left sitting out?

Hehe...Um like duh! *slaps forehead* *blames alcohol*

Yup, this is IC2, in Episode 1.
Cliff and Brice are sitting out for both Aparri and Solana.
Which, as concluded already, means David is the first boot.
Considering what JP had to say about him..."The thing going against David is the other 17 people probably don't live the world you live and they're not gonna come play your game. You're gonna have to go play theirs."... it appears, even in the caps ...

... as though David is confrontational, perhaps bossy, and this apparently won't fly. The game is his to lose. No real surprise there.

As to the 2nd IC...

For me it looks like Aparri's puzzle is done.
The fact that Cliff is sitting down does denote a non-celebratory moment for Aparri but it could indeed be a complete rout, they've already celebrated and are just being respectful of the continuing contestants.
It does look like Solana could be close to done, possibly the seventh piece but at that point the eighth piece is easy.
Who can tell where Luzon is at?
But judging from the facial expressions they both still believe they could win, so it's close.

And as stated by FP below, It doesn't look like LJ and Alexis' hug is celebratory.
But it is a hug. Which is usually celebratory.

Who knows.

For the boot at the 2nd TC...
Conclusive of future challenge caps, it is clear that: Trish, Woo, Lindsey, Sarah, Tony, LJ, Jeremiah, Morgan, Jefra, JTia, Garrett (most likely Spencer and Tasha too.) are all safe for both TCs during Episode 1.
This leaves Cliff for Aparri.
Highly doubtful it's him.
For Luzon, we have Tasha, Spencer and Kass.
I seriously doubt Spencer is going anywhere soon (even though he'll probably deserve it). The caps of him with Garrett and both Tasha and JTia means to me that the four of them are the initial alliance. After David, Kass is an easy choice for boot.
For Solana it's either Alexis or Brice.
Both believable but if anything is tied into the title, it has to come from Solana. How LJ or Jeremiah avoid being the target, I don't know. Both come off as the leaders.
And apparently Jefra, Morgan or Alexis is our grudgy Hot girl.
What I found interesting was these caps...

and...

There is apparently some sort of animosity between the two of them. Or at least Brice has found it okay to augment Jefra's standing in the tribe. Or at least her standing with him. Openly.
If Jefra is indeed our "weakest", as suggested at with the map, than it is completely plausible that Brice wouldn't be able to contain his "truth-telling"-self and let her know she's the target.
It's not only plausible that Jefra is our Hot girl with a grudge, it's gaining probability for me.
There have been plenty of caps that suggest that Jefra is on the outs. And to add to those...

The same story can be said for Morgan. There are plenty of caps with her being the pouty outlier.
But Morgan's interactions with Brice have ... up til now ... led me to believe that Morgan and Brice are on the outside of the "alliance" and maybe Brice tells Morgan that she's a goner and she "plays the game" and Brice is booted for pulling an S6 Alex.
Regardless of whether Jefra or Morgan is our Hot Girl with a Grudge, Brice is the victim.

Lesson re-learned. *crossing fingers*

Hey, I was thinking about re-animating a SOTS semi-tradition. I have some of it hammered out but didn't get enough time to finalize some details before the premiere. But it's coming... SOTS. State of the spoiling. Complete with post-show clue rehashing.
