Locke: I'm sorry. Sorry I ever doubted you. Sorry I gave up on my faith in the island. I messed up. And now our people are captured. If I had just listened to you, if I had just let you keep pushing the button. I could have gone with 'em, protected 'em. I coulda saved 'em.
Eko: You can still protect them, you can still save them.
Locke: I don't even know where they are.
Eko: You will find them. After all, you are a hunter, John.
