After Eko kills the thugs that attacked him in the church, Daniel asks him: "Are you a bad man? My mother says you are a bad man." Eko retorts, "Only God knows." On the Island, Eko recalls this conversation and tells the image of his brother that he wishes he had told this boy that he had no regrets about what he has done in his life, because he only did what he had to to survive and save his brother as a child. Daniel is one of the visions that Eko has on the way to the Beechcraft, which can be assumed to be the monster (like Yemi). He simply says to Eko, "Confess." ("The Cost of Living")
