In flashbacks, a mother, Joyce Malkin, claims that her daughter, Charlotte Malkin, drowned and then came back to life the next day. Eko goes to their house, but Richard Malkin asks him to leave. Charlotte finds him at the airport and says that when she was "between places" she got a message from Yemi. Yemi wants Eko to know that he's a good person and to have faith.

Jack, Kate, and Sawyer take care of Libby.

Michael is worried as he looks on. Jack says the best he can do is make Libby comfortable but only if he has the heroin from Sawyer's stash. Sawyer agrees to get it.

As they get ready to go back to the hatch, Hurley asks if they've seen Libby. Kate tells him what happened. Hurley is able to talk to Libby before she says, "Michael," and then stops breathing.

Eko dreams that Ana-Lucia tells him to help Locke. Yemi is also in the dream, telling Eko to help Locke. Yemi says to ask Locke about the question mark.

When Eko goes to the hatch, he sees that Ana-Lucia and Libby have been shot, but he's able to persuade Locke to go with him, under the guise of searching for the escaped non-Henry Gale. Eko asks Locke about the question mark and Locke acts as if he doesn't know what Eko is talking about. Eko head butts Locke.

When Locke comes to, he gives Eko the drawing of the blast door diagram. From the drawing, Eko tries to figure out where the question mark could be. As it gets dark, they walk through the jungle and come upon the burned out plane that fatally injured Boone.

They make camp and in a dream, Locke sees Yemi calling to Eko and having him climb a cliff.

Locke tells Eko of the dream and Eko climbs the cliff. From up above, he can see a circle on the ground where nothing is growing. He climbs down and bangs around the plane until he hits something metal in the ground. The two dig out two doors, and open them to climb down the hatch. It's another station.

They find an Orientation Video and see that what they have found is Station Five, The Pearl Station, of the Dharma Initiative. It is an observation station, where team members are asked to record what participants of The Swan Station are doing. The Swan Station members do not know that it's an experiment or that they are under surveillance.
