Further Instructions

Locke wakes up in the jungle. After the implosion. He's alive. But mute. No sound comes out. He builds a sweat lodge. Hut. Fire. Smoke. He needs answers.

Vision: Boone appears to him in the airport. He guides him through the terminal. Every survivor is there, in a scene representing their fate. Boone shows Eko bleeding: "You have to save him. He's next."

Locke finds his voice. He finds Eko. In a polar bear cave. Dragged there like prey. Locke pulls him out. Eko whispers: "You're going to find what you're looking for." Locke nods. The hatch is destroyed. But his quest continues.
