It takes us all day to make it back to the beach, but it's almost bearable without Miles's constant bickering. When we get back to the beach, everyone crowds us, asking about our new friends.

"This is, uh, Charlotte, and Dan," Jack says, introducing them. "Their helicopter already took Sayid and Desmond back to their freighter. They can make arrangements to get all of us off this island."

Sun walks up to me. "Where's Kate?" she asks.

I explain our trip to the Barracks and how we traded Miles for Charlotte. "But Kate stayed behind," I say. "Don't ask me why. I don't know."

Daniel walks up to us, Charlotte slightly behind him. "Um, I don't mean to be rude, not at all and I don't want to impose."

"What do you need, Dan?"

"Well, it's been a while since we've eaten. Do you all have a food supply?"

"You just walked through our kitchen," I tell him, pointing. "All of that stuff is food. Help yourself."

"Thank you, Tia," he says, turning back around and taking Charlotte to the pantry.

"Who are they?" Sun asks me.

"That's Daniel. He's the boat's physicist. And Charlotte? I'm not really sure what she does." I notice Jack sitting with Juliet, messing with the SAT phone. "Come on," I say to Sun.

"Maybe you should try a number other than the boat, like 911," Juliet suggests.

"What's wrong?" I ask.

"Nothing," Jack says. "I'm just having some trouble getting ahold of their boat."

"You haven't heard from Sayid?" Sun asks, surprised. "You said they left yesterday!"

"And I'm sure they're fine."

"What if Locke was right?" Sun says. "What if these people are here to hurt us?"

"Locke has no idea what he's doing," Jack says intently.

"Then why is Kate with him?" she counters. Jack doesn't come up with an answer and Sun walks away, hotly.

Jack tries the number again, but without success. "Come on," he says to me and Juliet, walking over to Charlotte and Daniel, who are playing a card game. "Hey. I've been calling your boat all day," Jack tells them, bending down. "Why isn't anyone answering?"

"We're here, how should we know?" Charlotte says. "If they're not answering, they're probably—,"

"Are you telling me there is only one line on that boat?" Jack asks, getting impatient.

Charlotte and Dan exchange a look. "There is another number that we're only supposed to use in emergencies," she says.

Juliet bends down, grabbing the phone from Jack and handing it to Charlotte. "It's an emergency."

"Put it on speaker," Jack says.

Charlotte dials a number. It rings and a British woman answers. "Yeah?"

"Regina, it's Charlotte."

"Why are you calling me on this number?"

"Minkowski wasn't answering. The people on the island want to talk to their friends, make sure they're alright."

"What friends?"

"They left last night! Frank took them up in the helicopter."

"What do you mean they took off? I thought the helicopter was with you."

Jack looks at me confused. Juliet looks worried. Daniel looks…not confused. I can't place his expression.
