Dawn is not "running" anything. True, she has been trying harder to play a sneakier social game, running to everyone and blaring her yap about everything she hears, but this has cost her emotionally which is funny as hell. Lindz is exactly right about Sherri. No way in hell you vote her off. Too much potential swing there. Phillip was the best choice for causing such a degree of climate change at camp (the fun sponge lolz) as to free people's minds to the idea of alliance shifts.
Andrea has been playing an interesting game with her flirting with Eddie, to keep an iron in that fire, but I don't see her as "running" anything either. No..everyone SAYS they were just humoring Phillip, but..he WAS running shit more or less, so there is an interesting power void open now.
All that said, it doesn't make sense for members of the numbers alliance to jump ship. It really is in their best interest to get rid of Malcom, Eddie and Reynold. I wouldn't be shocked if Cochran actually stepped up and tried to make sure stability of course ensued. Watching the "pretty people" come back from the grave to make a run for things is like that guy's worst fears come true.
