Reward challenge: a combination of gathering stuff (survivors racing towards the big wall), and perhaps assembling things in trays. This would appear to favor speed and agility (Eliza) and possibly puzzle-solving (everyone but Chris.) The wall appears to be symbolic of a volcano. On the wall are a series of red paths, all of which end in golden necklace-looking things (the real immunity necklace is visible on a pole at the base of the wall. It's not clear if the Survivors are meant to retrieve stuff from the wall, or if the wall is a key to solving a maze that lies behind it.) A TC marching shot features Eliza and Twila, neither apparently wearing the immunity necklace. Eliza is wearing her Mom's shirt again, for the first time since Ep11, when it was given to her. Twila appears to be wearing her buff on her head, which suggests this is new footage from the finale, since Twila wore her buff on her left wrist at the Ep11 TC. The question is: is this the Final Four TC, or the Final Three TC? If it's F4, Chris seems the most likely to have won immunity. This seems the simplest assumption, so we'll go with a Chris F4 immunity win (for now).
Immunity Challenge: As usual, there are no previews of this available, but it should be the traditional remembrance of the previous booted contestants, which will be framed this season as visiting with their "spirits." The actual challenge is a test of endurance that involves bow & arrows. This would appear to favor both arm strength and arm endurance. So Chris's feet and Scout's knee should not hold them at a disadvantage. Chris or Twila would seem to be the favorite here, though. But you never know, Scout or Eliza could hang on for a win too.
F2/Winner: Still being hotly debated on the spoiler boards. I think you’ll have to tune in to find out.
