The 23rd Psalm

Eko wants to see the plane. The Beechcraft crashed on the cliff. Charlie takes him there. Eko knows what he'll find. It's his brother's plane.

Flashback. Nigeria. Eko as a child. Militiamen force a boy to shoot an old man. Eko takes the weapon in his place. He fires. He saves his brother Yemi. But he loses his soul. Yemi becomes a priest. Eko becomes a gang leader. Years later, Eko uses Yemi's church to export drugs. The plane takes off. Yemi is on board. Shot by a bullet.

On the island, Eko finds Yemi's body in the wreckage. He recites Psalm 23. The smoke monster approaches. Eko doesn't move. He stares it down. The monster retreats. For now.
