RUBY: But you could come and see my dad. You don't do that, do you? Will I ever see you again?

DOCTOR: Of course you will. Of course you will.

RUBY: Your own granddaughter. You left her and never went back.

DOCTOR: And that was my mistake. Maybe I'll find her again, one day. But you, Ruby Sunday, I will see again. Because you changed me. I talk about family in a way that I never did before. That's because of you. You have made my life bigger and better. And now, Ruby Sunday… goodbye.

RUBY: I love you.
