We open this episode with Emily, in the sixties being knocked down by a car and taken to hospital, where she tells them she is pregnant and gives birth to a boy. She asks them to name him John. Through out the episode we see John growing up as a child, and through different stages of his life. The helicopter arrives back at the ship. Sayid plans to go back to the Island with Desmond but at the last minute Desmond pulls out. Locke, Ben & Hugo go to find the cabin, where Jacob is. When the pilot (Frank) doesn't agree to fly the helicopter back to the island, one of them kills the doctor. He then also kills the caption of the ship. Frank then hires up the helicopter and they take off. Back on the island they see the helicopter and something drops out. It's a tracking system. When they arrive at the cabin, Ben and Hugo both decide not to go in, so Locke goes in alone. They wish him Good Luck. He goes in and there is someone else there (the man that visited him all though years ago as a child), who says he can speak on Jacobs behalf. Claire is also there. He tells John to ask the one question that really matters and John asks "How do I save the island?"
When he comes out he tells Ben and Hugo that Jacob wants them to move the island. They both look at him as if he has lost his mind. How can things happen on the island (like dead bodies) before they have actually happened?
