The guys this season have been incredibly fragmented and stupid. I would never have gone along with giving the girls the number advantage last episode since even if I was in an alliance that I trusted I still wouldn't want the temptation of an all girl alliance being there to ruin things for me.
How stupid was Troizan in just swallowing it when the girl said that Mike was angling to get rid of him? If I was in his spot it would have set of every alarm bell in the world!
Kudos to Kim though, she is really playing the game well, she just has to hope that Alicia and Christina don't realize that they are at the bottom and might switch to a four way alliance with the last two males (it's the smart move for them).
