My sister's reaction to the episode was "they wasted two idols just to get rid of Phillip
" as she was expecting them to get rid of a strong strategist (namely Andrea).
Which actually brings up a fair point - and really increases my respect for Boston Rob's gameplay (despite the fact that I don't like him) because he dragged the person that everybody did not like to the end and that contributed to his win. Every season (well some) there seems to be one (or more) people that the rest of the castaways do not like (for whatever reason). And quite often the inability of the majority to put up with and keep that person costs them in the end.
Last season is a good example. Skupin and Lisa threw away a million dollars because they were incapable of putting up with Abi for three more days.
Phillip was definitely playing a different role to last time, but nonetheless that alliance would be smarter to boot a stronger strategist like Andrea (although I'm so thankful they didn't).
