I know the consensus is that the TV Guide 4/24 date is wrong, but what if it's right? All we have from the web clues is:
One Castaway has made too many promises to too many friends, leading to a Tribal Council in which she is forced to betray an alliance. One Castaway, desperate for friends and allies, makes the ultimate sacrifice in exchange for promises of safety from every single tribemate.
Let's say Jason wins immunity but gives it up for some reason. I've been assuming that this would be the blunder and would lead to him getting booted, but what if they actually honor his request? (Still not sure how or why he could convince them of this.) Meanwhile, if Parvati makes and honors her promise to not vote off Jason, then she'd need to choose between her other two alliances (she could go with Ozzy who would vote for either Alexis or Natalie because they're not faves and not his bud Erik, or she could go with the all-girl alliance and attempt to blindside Ozzy). Meanwhile, Jason would live for another week and make his even bigger blunder next week.

I just feel like I've been overthinking it all week. Sometimes it's the obvious solution, and sometimes they over-hype BEST TC EVER and then it ends up not living up to all the hype.
