LAST EDITED ON 10-15-12 AT 11:03 PM (EST)So, thanks to the CBS promos and CBS cybermonkeys let's examine what we do and do not know.
Denise and Malcolm have a clue to the HII and search for it. We do not know if they find the HII or if so which of them keeps it.
There is a Reward Challenge, all three tribes go to it, all 14 players. We do not know if Matsing is dissolved before that challenge, after that challenge, as a result of that challenge, or if they get to sit out because they are the reward (or part of it). We do not know who wins RC.
We do know that Matsing is dissolved. We do know that Denise goes to Kalabaw, Malcolm to Tandang, per challenge shots, though those challenge shots are probably IC. At least one shot has turned up showing Denise with all six Kalabaw, she does spend time with Dana.
We do know that Dana gets sick and that Probst and Medical come to camp to deal with the situation. We do know that Medical says it isn't bad enough for them to pull her from the game, it is her decision whether to tough it out or quit. We do not know what she decides: We do not know whether she decides to quit, to tough it out, or whether in toughing it out she gets worse and Medical later changes their position, or she changes her mind and quits.
We do know there is a challenge in which Abi is an apparent sit-out, so there is an Immunity Challenge and there will be a boot. This suggests that Dana was medically evacuated from the game as the tribes would be at equal numbers otherwise, or if she is still in the game Probst allows sit-outs because she is too sick to run the challenge (or some variation thereof). We do not know which tribe wins IC.
We do not know who is voted out of the game. At least not per CBS reveals (clues and hints and misdirections are separate issues).
Did I leave anything out? Oh, we don't really know anything about the challenges, but perhaps there will be a challenge preview for one of them.
