- "Let me tell you a story. There was a time when I didn't want to be around anyone... So I found a job that took me away from the world, away from everyone I ever knew, everyone I ever cared about... And then, when the world changed, when everyone went away, I realized I made the biggest mistake of my life [...] I couldn't help the people I had run away from, so I found a way to help the people who were still around [...] Just because you weren't able to help me, Luci, doesn't mean you're not going to be able to help someone else."
