The smart move was to remove him, and I think both sides figured that one out. I wonder if (because I certainly didn’t see it) the Couples alliance played Fairplay for the idiot he is. “That’s right Johnny, you tell the others that you want to go home, and they’ll all vote for YOU and we’ll vote for Eliza.”
Which they didn’t. BTW, I missed it - who did Fairplay vote for? Was it Parvati or Eliza - either one of them would have told the others which side Dalton was really on.
According to Wikipedia’s Survivor: Micronesia page, he voted for Ozzy.
