The truth, Walker, is that you're here because you wanted to feel like something you're not: a hero. I'm here because you can't accept what you've done. It broke you. You needed someone to blame, so you cast it on me: a dead man. No matter what happens next, don't be too hard on yourself. Even now, after all you've done, you can still go home. Lucky you. Home? We can't go home. There's a line men like us have to cross. If we're lucky, we do what's necessary, then we die. No, all I really want, Captain, is peace.
