I think this is where Raro gets a lot more pissed off and vindictive. Up until now, they were thinking it was a situation where they could be like, "Jonathan is so foolish; we never counted on how dumb he was going to be," and they could go out on that note. But he's basically just proved that not only did he successfully flip on them, but he wisely flipped on them, so there's really nothing for them to make fun of or to complain about. It was perfectly fair, and it was perfectly smart. In fact, it was basically his only choice, and they have nothing. Which means, of course, that it's time for the irrational vitriol.
So anyway, Jonathan says he knows the ex-Raros don't even believe him that Yul has the idol, and Parvati snots that he's right -- she doesn't believe it. Good for you, girl. You just keep on believing that Jonathan is making up the fact that Yul has the idol, and keep trying to vote him out. "Guess there's nothing to say tonight," Jonathan finally says. "We can talk tomorrow if you want." What I dig about Jonathan here is that he's not at all afraid to talk about what he did. He's not defensive, he's not denying it -- he's just telling them why what he did was rational and sensible, and he understands that they don't like it. Parvati says in her interview that she "called [Jonathan] out," which is idiotspeak for "pointlessly complained," and told him he's "a filthy, miserable rat." And then she smiles a little smile, because she has nothing to fear but the fact that she's going to lose, and she's going to lose ugly.
