Boone Carlyle

Boone is Shannon's stepbrother. He protects her. He finances her. He always comes back. Even when she pushes him away. It's his prison.

On the island, Locke takes him under his wing. They discover the hatch together. Boone finds purpose. For the first time, he exists outside of Shannon. Locke teaches him survival. The jungle. The hunt.

Boone dies climbing into a crashed Beechcraft. A fatal fall. The first survivor to die from non-violent causes. Locke carries him back to camp. Jack can't save him. Boone's sacrifice opens the path to the hatch. "The sacrifice the island demanded," Locke says.
