I can see a FTC of Rodney, Mike, and Carolyn. Let's say Mike and Carolyn make it to the F4 together with Will and Rodney and Mike wins, he probably does not want to take Will because of his behavior. If Rodney wins, he is definitely taking Will, but might think Mama C will be a bigger threat to win because of her challenge wins and because she did not piss off anyone. If Carolyn wins, Mike will definitely be a goner.
ETA: This is based on my fantasy boots of Dan this week, Sierra next week - though I would much rather see Mama C go next week instead of Sierra. If Dan uses his advantage this week on Mama C and she plays her idol, granted that Mike wins immunity, Dan will most likely go home as Mama C might need Sierra next week to vote with her. Next week, with Mama C vulnerable with no idol in play, she goes home.
