Because Juliet catches up with Ed strolling out of a building onto a city sidewalk. He's talking on his cell phone: "Because you're insufferable. And you're mean." Pause. "Well, you asked me for the truth, Mom." Hee! Kind of throwaway dialogue, there. (Is Ed the long-lost older brother of Michael Bluth?) I presume it's meant to distract us from the bus down the street in the distance. Anyway, Juliet gets Ed's attention, and he ends the call to his poor mother. "Hello, Jules. What's up?" Juliet tells him Rachael's pregnant. Ed's just as surprised as Juliet was, but he gathers himself together enough to say that he needs to see her labs so he can verify her data, but Juliet says no. "I'm not interested in publishing, Ed! It's my sister!" Ed says, "Excuse me a second; before I continue this conversation, I am going to, for some reason, step off the curb and STAND IN THE STREET WHILE I TALK TO YOU." Which he does, and then he starts to ask her something about why she's concerned, if she's not interested in publishing, but he's suddenly hit by a bus, to the surprise of very few. Which is not to say it wasn't still pretty funny. Well, maybe not to Juliet, who stands there looking shocked, while bystanders all around rush to help.
Back in the OR, Jack's back to work on Ben, with Zeke helping out, although Zeke looks like he's not much better than Hurley as an assistant surgeon. Jack asks if he's okay. Zeke says he just doesn't like blood too much. "Well, then, you probably won't want to be look at that," says Jack, holding up a piece of tissue, which he holds up long enough for Zeke to start getting ill, and then tosses in a tray. Jack asks why, if they can really get off the island, they didn't just take Ben to a facility.
"Because ever since the sky turned purple," begins Zeke, and I would really like to hear the end of that sentence since when the sky turned purple the Others were already holding Jack, Kate, and Sawyer hostage. But we don't get an explanation, because Ben suddenly starts spurting blood, and the heart monitor starts beeping.
"What the hell happened?" asks Zeke, and Jack says he just nicked an artery. "Isn't that what you already did?" yells Zeke, and Jack says, "Yeah, well, that was on purpose." Heh. Zeke asks if Jack can fix it, and Jack's too busy working on it to answer.
On the beach, Kate, Sawyer, and Alex have arrived at Alex's boat, which is some kind of outrigger. Kate's carrying Carl. "Nice ride!" says Sawyer, and Alex snaps at him to help her push the boat out into the water. "So, you're the boss's daughter, huh? I never saw that coming," says Sawyer. Alex doesn't say anything, probably already fed up with Sawyer's bullshit.
