Ruby: Ten minutes ago, you said genocide. Your people are gone.
Doctor: Yeah.
Ruby: How do you go on?
Doctor: For days like this, Ruby Sunday. I don't have a people. I don't have a home. But I don't have a job either. I don't have a boss or taxes and bills to pay. I don't have a purpose or a cause or a mission, but I have freedom. So I keep going to see the next thing and the next and the next. Sometimes it looks even better through your eyes.
