They're interrupted from considering this by a sudden clanging and hissing of the pipes. "Did you hit something?" asks Jack, and Sayid says, "I don't think so. I think it's coming from over there." Jack's going to go check it out.
He pushes up a grate in the floor and climbs out, as we see steam billowing along the floor and hear the sound of water on concrete. And it turns out, the entire Swan Station experiment is a contrived reason to get Kate a shower scene. Jack can't stop grinning as he asks a surprised, towel-clad Kate how the shower is, and she says that the pressure sucks and the water went cold at one point and it kind of smells like sulfur, but hey, it's a shower. "You could use one," she suggests, not in a "you stink" kind of way, but in a "concern for his welfare" kind of way, and she's not too pissed to be caught in the shower by him, but I doubt she would be. Maybe later, says Jack, and she says she'll leave the shampoo for him. Shampoo. His hair doesn't even grow, so he can probably wipe it off with a washcloth.
On the other side of the island, our heroes continue marching through the jungle with some of the other survivors. The woman in front of Michael stumbles, and he helps her, and she introduces herself as Libby. She asks how many of them there are on the other side of the island. "When we left, around forty," he says, and asks how many of them survived the crash. "Twenty-three," she says. End of the small talk.
At the back of the line, Otherbisi asks Sawyer if he's all right. "Now you give a damn," says Sawyer. Otherbisi says he said he was sorry, and that it was a misunderstanding. "A misunderstanding is when you bring me lemonade instead of iced tea," says Sawyer. Or a mint julep. Up ahead, Ana-Lucia snaps that she said "no talking!" "He was talking to me!" says Sawyer, which didn't work for anybody who used it for the last time back in Grade Four. Anyway, they're here, says Ana-Lucia, only there doesn't appear to be anything. Sawyer sarcastically asks if she's going to beam them up, and at some point I have to wonder if Sawyer actually enjoys getting beaned with rocks. Ana-Lucia ignores him, however, and pulls aside some brush to reveal an entrance, not surprisingly, much like Swan Station's. She knocks, and the door is opened from the inside by an older white gentleman, who, due to his skin colour, I'm going to state cannot possibly be Bernard.
