Once there, he takes off his mask. He and Kate look at each other. Oh, she's going to get executed now! "'I don't know how to use a gun'?" he says, and she laughs, and they start doing it right there. Shocker!
Back at the beach, Shannon's going over Rousseau's papers with Sayid. "You never said anything about math," she says. He didn't? Did he not tell her about the equations? Yeah, he did. I gotta say, I'm not sure if there's much point in getting her to translate the French if she doesn't even speak English.
She stares at the notes for a while, and then says she can't do it. Sayid gives her some Miyagi/Yoda bullshit along the lines of "you can if you think you can." And then he asks her where she learned to speak French. She vaguely says that there was this guy -- and Sayid sets his head on his hand in a gesture that clearly says, "Well, come on, girlfriend! Dish!" She says that she "kinda" lived in St. Tropez for a while. "Well, they say that is the best way to learn a foreign language," says Sayid. Living in St. Tropez? Really? They look at each other a moment, half-smiling, and that moment contains more spark than a season's worth of scenes thus far of Jack and Kate, Kate and Sawyer, Mercutio and Sun, or Locke and Boone. ["Told you. He is hot; she is awesomely bitchy; it's perfect. Get on that, writers." -- Sars]
Speaking of Sun, she's sprucing up what I presume is Jack's new waiting room with some plants. Jack asks them what they're for, and she starts speaking Korean. Perhaps she's hoping he's learned it since the last time they spoke? I don't know. So she pauses for a moment, likely figuring out how best to convey what the plants are for without giving away that she actually speaks the language. So she points at her temples and grimaces, and he says, "Headache!" and she's all, affirmative! And then Jack says "cool," whatever that's supposed to mean.
