Harding dives into Nemo's lair beneath the lake and is trapped in a chamber. Gideon is awakened by an intruder.

A tribe of native Islanders arrive on the island in search of Nui, a young native girl they believe has special significance.

Nemo fulfills a promise to Katira to bring the rest of her people to the island, then watches with glee as the natives take over Granite House and send the castaways into exile.

A tattooed native man arrives on the island telling the castaways that he is on a spiritual quest. Nemo is delighted when his presence has a disruptive influence on the group.

Nemo's hidden camera in Granite House breaks down, so he disguises himself as a shipwrecked Englishman in order to gain admittance into the house to fix the equipment.

A series of accidents leads Harding to come face to face with the mysterious phantom, and he struggles with how to share the shocking truth.
