Charlie just calmly asks Sawyer if he shouldn't be more concerned about Jack ransacking his tent. Sawyer looks down the beach, and sure enough
Sawyer angrily stomps over and demands to know what Jack's doing. Jack's just taking back the medicine that Sawyer apparently stole from the hatch, which Sawyer says he was just stealing back, or re-stealing, I guess, since it was in his stash when he left. "You don't have a stash anymore," says Jack, and Sawyer growls that Jack doesn't want to do this: "Just give me the pills, we'll forget it ever happened." Jack asks, "Are you threatening me?" kind of incredulously. Sawyer says, "Last chance, Doc," and intensifies the glare. Jack's all "later!" and strolls off; Sawyer seethes two holes into his back, thinking, "I wish I knew how to quit you."
Flashback, Sawyer's still shirtless, like this episode is going for some kind of record. He's in bed, either pre- or post-coital with a brunette whom he's nuzzling and asking, "What do you want, right now?" "Just you," she whispers. They make out a little bit, until his eye catches the clock on the night table. He says he's gotta go, or he'll be late for the meeting he told her about. She says, kiddingly, that if he's got another date, he can just say so. "I can only wrap my mind around one woman at a time," he says, getting dressed, "but I appreciate the permission." He grabs his briefcase, which opens, spilling bundles of money everywhere. "You weren't exactly supposed to see that," says Sawyer, chagrined. By which he means, she was supposed to see exactly that, and this is exactly like the other con he was pulling.
The difference here, though, is that she doesn't fall for it; she giggles and can't believe he's serious, that he just happens to have a suitcase full of cash and the lock just happens to break. Sawyer stares at her. She scootches forward on the bed and grabs some of the money from the floor, evading Sawyer as he tries to stop her, and discovers that it's not real money. "Are you trying to con me? What, I ask you what all the money's for and you do some song and dance about an investment or something, and then I say, 'Hey, you know, I've got some money'?" Sawyer sits on the end of the bed, listening, and then says, "Look, you got me. Good for you. No harm, no foul." He gets up to go, and she tells him that he should have done his homework, since she "didn't take anything from him in the divorce. I'm not even worth your trouble." Sawyer looks like this is news to him. "Shame on me," he says. And then, she says this: "I want you to show me what you do," and she crosses the room to get close and says, "Show me how you con people, Sawyer." Because asking the con man to get out would be a dumb idea, I suppose.
