I kind of agree with Spidey. I think maybe Rupert thought things out a bit. Getting rid of Jenna means there is a 4-way "alliance" because it was clear that Ethan and Tina were going to stick together. By getting rid of Tina first, he risks getting Ethan a bit upset, but I think that the fact that Jenna is so dead set (and up front) with voting off the previous winners that there is no question that Ethan will join in with the guys instead of the girls.
I think it is a shame that Tina had to get voted out, but stratigically, it wasn't such a bad call. Of course, it also doesn't show much faith in their tribe. After all, if they can avoid voting off two more people before any tribal shake-up, then there isn't a problem.
Jerri's been pretty tame so far. We'll see if that's a change of attitude or just a facade. She seems to have decided to keep her mouth shut...interesting.
Very interesting that Sue and Richard are playing a very similar game of just kicking back and letting everyone else do everything. It's also interesting that it seems like that strategy may actually work for Rich, but Sue is likely to get the axe first chance they get.
