Actually, it's Yemi, who gets out of the van and says he came to stop Eko, who tells him to go back to his church. "Do not get on that plane, Eko. You saved my life once and now I'm here to save yours." If Yemi shoots an old defenseless man, that'll be kind of unexpected. Yemi doesn't want Eko to get on the plane: "Let me take your confession. Anything I can do, I will do. But please, don't go." Wow, Yemi offers to take his confession. He's pulling out all the stops.
In the distance, we hear sirens, and we see a truck full of soldiers standing up in the back come speeding around a corner. In the first shot, I might be nuts (and the television I'm watching this on, again, kind of sucks), but it looks like the soldiers don't even have their guns out, which seems kind of reckless when you're swooping down on murderous drug dealers. Goldie yells that Yemi called the military, and I guess it's keen insights like that that have allowed him a place at Eko's right hand. Yemi says he didn't tell them who was involved, that Eko should just leave the drugs and come back with him.
Meanwhile, Goldie and the other guy open fire. If they want to continue posing as priests, they should probably at least have the Commandments down, you know? A bullet hits the windshield, and the truck swerves and crashes. The other guy, not Goldie, actually stops firing, all pleased with himself, somehow forgetting that there's a whole truckload of soldiers there, and he gets shot in the chest.
Yemi decides the best place for him is the crossfire, and he runs out yelling at the soldiers to stop shooting. Which they don't. And Yemi gets hit, and Eko embraces him, yelling, and gets Goldie to help load Yemi on the plane. But when Eko tries to get in himself, Goldie puts a foot in his chest. Eko leaves streaks of his brother's blood just inside the door and falls to the tarmac. Goldie closes the door and the plane taxis away. The sound of the gunfire dwindles to just one or two every few seconds. Either that or my microwave popcorn is done.
Back on Craphole Island, Eko climbs into the plane. He looks around, sees smashed-open crates with Virgin Mary statues scattered about. He looks at the doorframe, sees dried brown streaks of his brother's blood.
Towards the cockpit, he finds a body. This time, when he opens the shirt, he finds his old cross. He sits, and he stares. For a long time. And slowly, effectively, he starts to cry. He's even drooling. He hugs his brother's corpse and whispers, "Forgive me."
