Over at Drake, they're having a discussion about who's going to sit out the challenge. They're up two on the Tribe of the Damned, so they'll have to sit out two people for the next challenge. Jon is lecturing to the tribe that if the challenge is physical, he'll sit out, but if it's not, he won't. I guess he doesn't want to deprive them of the use of his giant, pulsating brain and its accumulated wisdom. That's a relief to the team, I'm sure. Unwisely, he next decides to tangle with Sandra, declaring that if the challenge has swimming in it, she isn't such a strong swimmer and should sit out. Note that it's not Sandra's turn -- she sat out a challenge last week. So he's specifically plucking her out to pick on. Sandra -- irritated but not speaking particularly loudly -- asks Jon why he thinks he's a better swimmer than she is. Jon and Sandra get into a silly spat over who did a better job swimming from the boat to shore on the very first day. She opines in an interview that Idiot Jon goes after other people in situations like this because he's sensitive about the fact that he's actually the weakest person in the entire tribe. Probably so. At any rate, Jon eventually escalates the argument with some yelling and swearing, which Sandra does not appreciate, and that's when it degenerates into a full-on shouting match. Jon walks away, apparently being one of those guys who's unable to deal with chicks who don't shut up when you yell "fuck" at them really loudly. (Hint to Jon: You might start with a chick who doesn't have a history in the military, nitwit.) "I walked away because she can argue all day long; that's because she's foolish," Idiot Jon fibs condescendingly in an interview. Wow, Beavis is calling Sandra foolish. I'm sure that cuts her to the bone. "Screw Jon, 'cause he's an ass," Sandra interviews calmly. Heh. "Her days are numbered," Jon returns menacingly in a voice-over. "We have bigger threats to get rid of first, but she's not one of the final four." Now he giggles and interviews that he's got "a mil that says she won't be the final one." You know, if you're going to try to be a bad-ass, you could at least learn to make threats without sounding like you're in seventh grade and you're threatening the head of the chess club with a killer wedgie.
