(Ellie is reading Bill's letter to Joel...)

Bill: Anyway... I never liked you, but still, it's like we're friends... almost. And I respect you. So, I'm gonna tell you something because you're probably the only person who will understand. I used to hate the world, and I was happy when everyone died. But I was wrong because there was one person worth saving. That's what I did. I saved him. Then I protected him. That's why men like you and me are here. We have a job to do. And God help any motherf**kers who stand in our way.
