Over at the makeshift kitchen, Jin haltingly asks Jack to pass some cereal. Mmmmm, Dharma Flakes. They chat about Jin's new language skills -- he understands better than he speaks, and both Sun and Sawyer have been teaching him. Sun walks up and looks oddly at Jack. She's clearly waiting for him to leave, which doesn't make much sense, as I'm pretty certain they can speak in front of him without him understanding a word. However, she does wait for him to leave before telling Jin (in Korean) to do exactly what she says and not ask questions. He breaks that rule right away by asking what's going on, and she tells him to gather enough food for two days. She wants to be ready to leave in twenty minutes. Where are they going, you ask? To join Locke at the Barracks. Commercials.
Sun is poking around in the medical supply tent (I think that's what it is) when Juliet walks in and asks her what she's looking for. Sun tells an unconvincing lie about searching for more pre-natal vitamins. Juliet goes to find them, and asks Sun what happened to all the other ones she gave her, since there should be twenty left. Juliet asks if Sun is planning a trip. Sun's non-denial is pretty much an admission, and Juliet asks her where she's going. She's not thrilled to hear that Sun and Jin are planning on going to the Barracks to join Locke. Sun tells her that she doesn't trust the Boaties, but Juliet reminds her that if she doesn't get off the island soon, she and her baby will both die. But Sun doesn't just mistrust the Boaties -- she's clearly not believing Juliet's story about all the dead baby mamas. Juliet cops to having been "less than truthful about certain things since coming here," but she promises that she's not lying about the pregnancy illness. She continues, "After everything you confided in me, I should at least have your trust." Sun tells her that Aaron came out fine, so she has no reason to think she can't also deliver a healthy baby on the island. She tells Juliet that she doesn't trust her, and then snatches the vitamins from her hand.
