At the moment, Shannon is traipsing through the jungle with Sayid leading. He's being all mysterious about where they're going, to such an extent that Shannon thinks he's actually Lost, or possibly just lost. He recognizes some trees, though. "It's this way, I think," he says, and keeps going. "Did you just say 'I think'?" asks Shannon, who nevertheless follows him. And it turns out another stretch of beach is right there. And Sayid has set up some sort of beach picnic. "Surprise," he says, and Shannon beams.
In the jungle, Jack is frustratedly throwing shit around when Charlie comes back. "I found an A," he tells Jack, who asks if it's positive or negative. "She doesn't know," says Charlie, who says he also found two B-positives and one AB-negative, "at least he thinks so," like, Charlie, this wasn't a bleedin' blood survey. Jack asks if he found any O-negative. "Sun said A-negative!" protests Charlie, which didn't seem to prevent him from finding out the other non-A-negative blood types, but whatever. Jack asks where Sun is, and Charlie says they split up, and he figured she'd be back here. "You only asked four people?" says Jack, and Charlie snaps that he asked the "whole sodding camp" but nobody knows their blood type. "I don't know my bloody blood type!" Oh, fine: heh. Sun shows up, and Jack asks if she found Shannon. Sun says no, that she was getting something for Jack, and she holds up a sea urchin. She plucks one of its spines, and tells him it's a hollow needle that's sharp enough to pierce a noodle. Jack's all impressed with Nurse MacGyver and says it's perfect. Then Charlie reminds him that they still need someone who's A-negative. Or O-negative, says Jack. "Right, which, judging by your tantrum, no one is," says Charlie. "Someone is," says Jack. Charlie deduces that Jack is, and starts spazzing, wondering why Jack made him ask everybody, and Jack quickly shuts him down by telling him that O-negative is universal donor. "It's in the ballpark, but it's not perfect," he says, adding that his blood could potentially send Boone into anaphylactic shock, stop his heart. "You mean he'll die?" says Charlie. Well, as we all learned from Itchy and Scratchy, you need a heart to live, so I'm going to assume that yes, Charlie, if his heart stops, he'll die. Everybody looks at each other all nervously, knowing full well that if the death is another fake-out, the audience is going to be pissed.
