In the boathouse, it looks like Locke has taken more drastic measures to ensure Miles's captivity: Miles now has his hands tied together above his head. It doesn't look very comfortable. Locke walks in. "I don't know what you think you're doing, but you're wasting your time," says Miles. Locke ignores this, pulls a grenade out of his bag, and STUFFS IT IN MILES'S MOUTH. He tells Miles to bite down; Miles does so, biting down on the handle, and Locke then PULLS THE PIN. He says he made the mistake the other day of not introducing himself: "My name is John Locke. And I'm responsible for the well-being of this island. Eventually, Miles, you're going to tell me who you are, and you're going to tell me about the people on the boat, and you're going to tell me why you're so interested in Ben. In the meantime, you're going to keep your mouth shut." Muffled protests from Miles. Locke, zipping up his backpack, says he learned yesterday that it's no good having rules if there's no punishment for breaking them. "Enjoy your breakfast," he says, and walks out. I'm sure the grenade will turn out to be a dud, but Miles doesn't know that. Fortunately, we're spared watching the trickle of urine running down his leg (or worse).
Sawyer and Kate are asleep, entwined in bed. Kate nuzzles him, climbs on top and starts kissing him, he flips her over, and then she gets all reluctant on him. "Come on, it's not like we've never done it before," he says. He also adds that he's cool with the fact that they didn't "go all the way" last night, because she was sad. Funnily enough, Kate is immune to the charms of someone displaying the sexual maturity of a fifteen-year-old, and she demurs, and it's only a matter of time before Sawyer says something like, "It's different for guys. We could die if we don't do it." She turns away from him on the bed and says, "Forget it." "You're still worried you might be pregnant," he says, which I suppose is the only possible thing he can fathom that might explain a woman not having sex with him. She turns back to him, and props herself up on her elbows. "I'm not worried. And I'm not pregnant." Sawyer busts out the "woo-hoo!"s, to the extent that Kate asks if it would have been the worst thing in the world. Sawyer's answer is "yes," in so many words. "What would we have done with a baby?" asks Sawyer. Like there would have been any "we" about it where Sawyer's involved. "I'm going back to the beach," says Kate, which only sets Sawyer off more.
