Back on the Elizabeth, Sayid's praying on a mat on the deck of the boat, finally confirming explicitly that he's Muslim. Up the deck, Jin and Sun watch him (and each other) smiling. I've got ten bucks that says Sun's about to say to Jin, "Honey, I just had kind of a wild thought. Maybe we could talk to Sayid about --" but she'd be interrupted anyway, by Jin spotting something on land. He runs over to hand the binoculars to Sayid. Sun takes the ship's wheel, regretting that she's missed her chance. Sayid looks through the binoculars, and sees the stone wall with the hole in it. "We're here," he says. Uh, how does he know about that wall? Did I miss something?
Charlie's leading an anxious Eko through the jungle to where the remainder of the dynamite has been hidden. Given that Charlie wasn't in on any of this, I'm wondering how he knows this. Oh, he says Hurley showed him. Oh, OKAY THEN. Charlie seems quite happy to help Eko. There are only a couple of sticks of dynamite left, and Charlie urges Eko to be careful as he unwraps the package, saying he doesn't want to wind up like Dr. Arse.
Charlie and Eko enter the hatch, with Charlie STILL saying "careful!" to Eko, so I imagined Charlie saying that the entire way back to Swan station, which sounds about right. If I were Charlie, though, I wouldn't be NEARLY so close to Eko.
Eko starts setting the dynamite in place against the door. For some reason, now is when Charlie starts wondering if this is a good idea at all, and asks Eko what if they hurt Locke and Desmond, or blow up the computer. "You can leave now, Charlie," says Eko, whose dismissiveness is really starting to bug me. Eko sets the fuse, as Charlie decides to spill the beans to Locke, yelling at him to open the door so they can work things out, and warns him that Eko's planning to blow open the blast door with dynamite. Inside the computer room, Locke looks quizzically at Desmond, who smiles confidently. "It would take an atom bomb, brother. Tell him not to bother." Locke asks if he's sure, and Desmond says he is. He looks over at a metal cart with a crumpled top that I don't remember ever seeing before. But I have a lousy memory, and I'm sure someone will correct me if I'm wrong. Besides, something tells me the upcoming flashback might give us some more insight into the blast doors.
Sure enough, in the flashback we see Desmond with the same cart, wheeling it into a doorway. He's now got on an official Dharma jumpsuit. In the kitchen, Clancy is pouring detergent into a measuring cup and stirring it with a paint brush. He asks if Desmond's ready. Desmond says maybe Clancy should do it, whatever "it" is. "Come on, Des. You've seen me do it a hundred times," says Clancy. So Desmond strolls back into the computer room, and touches a couple of bare wires on the control panel together, until there's a spark, and the now-familiar countdown comes on, preceding the alarm and the doors slamming shut, only one door slams neatly into the dent on the cart, and stops about waist-high. Desmond's quite pleased with himself. He doesn't know what Dharma's going to subtract the cost of that cart from his paycheque.
