Flashback to the Nigerian village from the first scene. Outside the church, a woman is selling Virgin Mary statues as Eko strolls up. "Sir! Sir, if you buy a statue the money will buy polio vaccine for the village. Two-hundred naira, sir." Eko's examining the statues when a young priest comes out of the church. "What are you doing here?" Not hostile, but not friendly either. "I have come to give my confession," says Eko, and the two of them break into smiles. "Hello, Eko." "Hello, brother."
Inside the church, Eko gripes that he's come to visit for the first time in three years, but his brother won't hear his confession. "You know, Monsignor would have said he failed to raise a proper Catholic boy." Eko's brother, still smiling, asks why Eko would waste his time confessing, since it won't help him. "For confession to mean something, you must have a penitent heart." We learn that Eko's brother's name is Yemi as Eko chides him for his guilt: "I've only done what I needed to do to survive. How is that a sin?" Look, guy, it's the Catholic church: everything's a sin. Yemi's smile is long gone. "You may live far from here, but that doesn't mean I have heard of who you are and what you have done."
Eko reaches forward and pulls on Yemi's cross, the same one that Eko used to wear. "Have you forgotten how you got that cross, brother, the day they took me? Is what I did that day a sin?" I keep telling you, Eko: yes. "Or is it forgiven because it was you that was saved?"
The brothers sit down in the pews, and Yemi asks why Eko is here. "I have come to help you. I have some merchandise that I need to get out of the country. I would like to use one of your church relief flights to transport it." Church relief, Eko? But you don't even believe in Jebus! Yemi's not fooled; he knows that "merchandise" means "drugs." But Eko concocts some story about how it's not his normal business, and he's moving the drugs out of Nigeria so they can't be used by their people. "And the money -- you'll have all the money to buy your vaccine. God has given us this opportunity; we should not turn our back on it." This is a new one on me: trying to claim that the drug deal is a God-given opportunity.
