OFG,I have thought about nearly everything that you have posted.
The problem I have with this episode is that I have been trying to reconcile the promos that hype a potential medevac in the shocking final seconds that no one saw happening with the press release that gives a teaser about a conspiratorial Tribal Council.
The promo makes it appear that episode 6 ends with the medevac rather than a Tribal Council. I had thought that perhaps the press release teaser about the conspiratorial TC might be for week 7 instead, until I noticed that Colton is missing from some of the Manono camp promo footage as well as being missing from the day 3 press image of the Manono tribe.
I started to wonder if Colton might be the evacuee but I don't see how a TC where Jeff reveals that Colton has been taken out of the game would be conspiratorial except for Alicia and Christina having another argument.
I still think that Tarzan is the evacuee because of all the attention that was given him at the episode 5 TC in comparison to the first 4 episodes where he had virtually no character development. It was as if Tarzan was being given a send-off before he is taken out.
Regarding the immunity idol stand being absent from the challenge, maybe the aerial shot was taken before the stand was set up. Generally we see the immunity idol stand next to Jeff when we get Jeff in actual active footage while the challenge is running.
Oy, and I thought analysis for week 4 was confusing.
