I agree. This alliance has their A game on. Only a twist from the producers will keep them from systematically removing their foes. There are 10 left. The strong onions are Marcus, Charlie and Corinne. I think they also control Randy and Bob, at least as their ticket to get further in the game (they would be fools not to see that this is short sighted).
Suzie hasn't shown any game, or she might be smart enough to realize she is next from that tribe (she did get 3 votes!).
I wonder if Sugar, seeing the futility of her current tribe, will try to get back into the onion. Marcus is weary of her HII (almost sure she has it), so bringing her into his alliance would be the smartest thing to do.
So who's next? I suspect that Crystal and Matty could be next targets. Matty has been the most competitive of the Fangs, and Crystal must scare people with her negative attitude and size.
hmm...
