DOCTOR: Once upon a time, late on Christmas Eve, a stranger came to the church on Ruby Road. She carried in her arms the most precious gift of all. A newborn child. A baby girl. Just before midnight, she left her daughter on the steps of the church. The child was taken in, and they named her Ruby, after the place where she was found. As for the mother, she was never seen again. No one ever knew her name, until that night a time traveller came to call. A traveller known as the Doctor.
