no he didn't. he voted for kass.
He may have known that Trish would have a big chance of going, so he just voted with the majority so he wouldn't further isolate himself from the tribe. Just my guess.
But before someone says he could have spared her with the idol, he may have also been paranoid again and not want to risk going. After that, it'd still be 2-2.
He did vote for Trish...
.
And this is why...
I don't know... at least it's Tony input...
It kinda make sense, though... She was a social player... He might have get some votes in the final... IMO it was a bigger threat that Woo and Definetely Kass... and was the weakest at challenges... I think priority number one for Tony must be to Vote out Spencer.
I feel that Tony realized that he wanted Woo at the end, and consulted him if either Kass or Trish. When Woo said that he wanted Trish out, and seeing the majority was voting against her he decided to vote against her. That also makes the "Final Four idol" more realistic and also votes out a social threat IMO (I feel that Trish would come out in FTC and say her story). I agree also that Trish is less likely to help win challenges than Kass or Woo (then again Kass doesn't seem help in challenges too).
