While sleeping, Mr. Eko is assigned by his brother, Yemi, in a dream to go with John Locke to disclose the meaning of the "?" symbol, which Locke previously saw painted on a blast door in the bunker. With the pretext of chasing the escaped Henry, Mr. Eko brings Locke with him, and they find a second hatch near the Beechwood crash site called Station 5 "Pearl," part of the Dharma Initiative in a vast underground bunker with the question mark symbol marked on the field. A video explains that the other hatch is a psychological experiment, and the people in it are actually subjects. More of Mr. Eko's background story shows him as a priest at a mission in Australia where he is sent to investigate a possible resurrection miracle. The possibly resurrected girl gives him a message from his late brother, which she received during her near-death state. Meanwhile, Jack unsuccessfully tries to save Libby after she is fatally shot during the escape of Henry, all of them unaware that the murderous but guilt-ridden Michael was the one responsible.
