I would say Kyle is just as bad as Mitch about riding coattails at this point by not using his alliance with Kamilla to flip the game. This was the week where they could have voted out Joe and flipped it but once again Kyle was too scared to rock the boat and played the safe vote which is what Joe pitched. If Joe gets to the end he is winning at this point. The only way anyone but him wins at this point is voting him out. You already had Mary and Kamilla onboard with voting out Joe and Kamilla even set it up with playing it cool with Eva. My guess is Kyle chickened out and thus so did Kamilla and Mitch too because if there were 3 votes on Joe then you know he's gunning for them next vote with the power he and Eva have with SWP and the idol plus the odds he might win immunity too.
Joe has been my favorite from day 1 so rooting for him to win it. His game reminds me a lot of another firefighter that is my all time favorite winner which is Tom Westman. Tom won a lot of immunity challenges, was the leader of his alliance, and was well liked by most on his season thus he won 6-1. Joe is setting himself up to have played a very similar game I think if he makes it to final tribal. I'm perfectly fine if the strong 4 make it to the end because most seasons lately the strongest players don't make it and we are stuck with some less deserving options.
We know Eva has use or lose her SWP next vote so that could be a big thing to save one of her or Joe or maybe 1 of their other alliance. Is her idol good till final 4 or 6? That is going to play a factor soon too.
