the problem i have with Exile island and CI is that immunity idol, huge HUGE advantage... + they just couldn't split the votes cause it was strong 4 versus 6 after the merge... candice might not be smart but neither is Jonathan. he was not a sacrificial lamb so why didn't he flash the idol from Yul, i know why because he is dumb bitter bitch...
In CI, there was never a time when they could split the vote to flush out the idol. When they went in for the merge, there were 9 people, which was 4 v 5. Yul, Becky, Sundra and Ozzy were always voting the same way, which meant that targeting Yul would be a disastrous move for the other 5 people because they would lose a member of their alliance if Yul was to play his idol had he been voted off.
Flushing the idol in this season was more difficult because it would have meant that Yul had to be voted out before he plays it. Furthermore, the very first merge, Yul threatened Jonathan with the idol saying if he didn't join their alliance, they would target Jonathan and Yul would play his idol, meaning that Jonathan would be out. So Jonathan had to risk sticking with the 5 and vote for Yul knowing he'd play the idol and one of them would be going out or switch and vote out who he wanted.
All of this could have been avoided if Jonathan and the other 4 had voted off Sundra or Becky. But if I remember correctly, Nate and all them were quite adamant on voting out Yul, which meant that Jonathan knew for a fact that one of them were going home since they didn't know that all 5 voting for Yul would mean Yul would play the idol.
