Ruby and The Doctor in “Space Babies”

How do you keep going?

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, or rent, or bills to pay. I don't have a purpose, or a cause, or a mission, but I have... freedom. That's why I keep moving on, to see the next thing, and the next, and the next. And sometimes... It looks even better through your eyes.
