I love Sandra, because she's such a good, under-the-radar player. She has an amazing social game. You noticed how she was mentioned as a threat last night, but still didn't get a single vote. Also, the goat thing with her didn't bother me--I think it's partially cultural, and your own experiences. People in other countries eat goat all the time, and growing up, I had an uncle raise goats for food and milk. The only thing I think she's doing wrong is being too smug with her whole "I'm the queen!" thing. It's one thing to say that in your diary time, but you shouldn't be saying that to the other players. Although they may be thinking, "she thinks she's the queen, but she has no power". I say that because I suspect she's really, really good at planting a seed in someone's head, and having them think it's their own idea, which is how she stays alive in the game.
I was really sorry to see Malcolm go, that sucked. I'm not sure what Hali's game plan really was at tribal. Also, I'm not sure Tai made the right move by telling people about his idol. Sure, it worked to his tribe's advantage last night, but longer term, it might have been better for Tai to keep it for himself.
