I still don't think Carolyn has much of a pitch to the jury, perhaps the opposite. Aside from the lack of challenge wins, she's been vocal about being left out of the vote and people not listening to her all along. Sure, hiding her idol was good gameplay and surprising for such an open personality, but it's not enough, and when she did play it, it wasn't actually necessary (she likely didn't know that, but the result is still the same). There's a possibility that just her personality and relationships might have done it against the right opponent back in the day, but not now with two others to choose from.
That being said, was writing down Lauren's name and then scribbling it out a strategic move? To give the impression that Tika is not fully together? To make Lauren nervous? If it was just Carolyn being indecisive that's one thing, but I don't recall a ballot like that ever being shown before.
I too noticed the flames in Carson's glasses, but surely he's prepared for this like he seems to have prepared for every other aspect of the game. One thing I keep wondering about is why the voting table is a chess board, complete with pieces. Sure, just an expression of game play, but not very South Pacific. Wouldn't it be fun if instead of building fire at the end, they had to sit down and play a game of chess?

One might think it unfair, but what if during their interviews etc they did determine that all the players had some knowledge of the game coming in and no one was a tournament player (it would be a pretty normal question to ask for a show like this) and then it's been sitting there in plain sight the entire time. Probably won't happen, but fun to think about how it would go if it did.
I know a lot of you like Heidi, but at this point if she wins I will be disappointed. Not seeing enough confidence and real game play from her at all. I'm still rooting for Carson.
