Ana-Lucia points out that he was gone for two hours yesterday, and Nathan says that he was going to the bathroom. Was it really two hours he was gone? Because if it was, shouldn't there be a little more to it than that? I mean, I'm as likely as anyone to bring a Sports Illustrated in there with me, but...two hours? You read the letters, check out that gossip section where it tells you what Anna Kournikova is doing these days, skip the weekly book excerpt/inspirational feature on athlete overcoming adversity, and then you're cruising through "The Week In..." and skim Life of Reilly and you're good. Two hours? Oh, I know! He's supposed to appear suspicious! Goodwin interrupts the impromptu interrogation by pointing out that everyone's scared, but there's no need to get paranoid, as they don't know anything. Hey, don't sweat it; twelve people have been kidnapped, but LET'S NOT GET PARANOID. Bernard thinks it's crazy they would try to infiltrate the group, which is true, but -- given that we've seen the results, are the motives that important right now? Libby says they have to leave the beach, since the Others know they are there. Ana-Lucia looks at Goodwin. "You said we needed to keep the signal fire burning." He quietly says he thinks it's time they let it go out. She ponders this, while at the same time managing to glare at Nathan all I'm not done with you yet.
It looks like Ana-Lucia agrees with Libby and Goodwin (Eko presumably not offering his opinion), but she's probably thrilled that she gets to lead one of her Bataan death marches through the jungle. They come across a stream, so she lets everyone break for five minutes. "We've been walking for three days straight, Ana," complains Bernard, who looks like he's already lost thirty pounds. "And you're still here. Five minutes," says Ana-Lucia, in some nice post hoc, ergo propter hoc fallacious reasoning. But Nathan has other ideas: "You want to keep walking? Go ahead. Fresh water, rock wall at our back, lots of fruit trees -- right here looks pretty good to me." He unshoulders his pack, and he and Ana-Lucia look at each other, with the rest of them looking at her to see what her reaction will be, before she finally says, "Fine, okay. This'll work," the way you might pretend to give permission to someone who's already made up his own mind.
