Here, rather hilariously, a bunch of teams crowd around Rob and Amber to bitch at them like townspeople with pitchforks, and Bianca gets all up on her high horse and says, "Lying to somebody is completely different." Lying about something that, one way or the other, is already done and is at worst sneaky rather than harmful to anyone? Who cares? What obligates you to tell the truth about that? Whatever. "Tell me what I lied about," Rob says. Here, an amused Amber reaches out her hand, touches Rob on the elbow, and says, "Calm down." She's been here before, you can tell. Debbie and Bianca decline to specify what lie they're talking about. "Because there is nothing," he repeats. "Accusing somebody of lying; that's personal." "It makes me nauseous to have to deal with that kind of stuff," Debbie says, actually throwing her scarf over her shoulder so as to become a more complete caricature of the Mortally Offended Fairy Princess. Rob says it makes him nauseous to have her call him a liar. "Let's just say it's a good thing that people can't be voted off," Lynn snots. As the rest of them stomp off, mad and distracted and thinking about everything except playing the game, Rob looks toward the camera, grins, and winks. I tend to agree with people who say that this isn't smart strategy on his part in the age of the Yield, but Rob plays reality shows just like he would play poker or Monopoly, never seriously taking anything particularly to heart, and I find it intensely refreshing.
More generally, to me, the whole thing is just a bunch of moralizing nitwits who would do precisely the same thing if they were able to. Why didn't Debbie and Bianca do exactly what Rob did before he ever got there? Because they didn't think of it. They sat around on their fannies all, "We'll just go in order of arrival on the most obvious bus." They have absolutely nothing to be snooty about, because Rob would have had nothing to fool them over if they had done what he did when they got there, so their affecting an attitude at this point is a transparent case of envy and sour grapes. Which is why Rob is amused, as am I, once I get my eyes to stop rolling back in my head at how goofy some of these people are being.
