Even though I can't stand Coach, it was pretty stupid to vote him out. The Villians are getting absolutely worked and to keep rail thin Courtney or dumpy Sandra around was a huge mistake. I don't see a merge happening for at least another 2 weeks.
I find the analytical processes of the Heroes to be pretty lacking if they automatically think it's a girl alliance on the other side without considering other alternatives. Could be their downfall, who knows.
No, they aren't. This basically comes down to Russell and Parvati overruling Danielle in that they are pushing the all girls alliance and the fact that Coach is the first jury member makes it even more likely that there is a merge next episode.
Also, while I normally would 100% agree with the "ignore the promo" mantra I got a feeling that this just might be one case where they actually follow through on giving a pretty accurate promo. The heroes aren't the brightest bulbs on the tree and I could see them running right to Russell to to try and "pick up his vote" against what they see as an all girl alliance that they would have to contend with. They have NO CLUE about what Russell is really like. None whatsoever and Russell set that "Russell Seed" as Probst likes to say and JT and Rupert, certainly no candidates for the Mensa club, I could easily see falling for it.
