Mike wins immunity and plays the idol for Dan since that's who everyone will be targeting. They vote out Tyler/Wil/Carolyn/Rodney.
Sierra flips at the next tribal council and Dan uses his extra vote. This gives them a four to three advantage over the remainder of Tyler/Wil/Carolyn/Rodney.
Just an idea, I wouldn't mind this.
If not, Mike and Dan are probably the next two out.
Carolyn/Tyler and Rodney/Wil are going to be vying for Sierra's vote at F5 rather than voting her out I think.
