DONNA: Why did this face come back?

DOCTOR: I don't know.

DONNA: To say goodbye?

DOCTOR: Oh yes, I'm the Doctor. I'm all bon mots and bonbons, but right now I'm furious! You took away so many people, the unwanted, the unloved, you promised you'd make their lives better- liar! Instead, you threw them into your machines, how cruel of you. And worst of all, you took away Professor Bernice Summerfield. I would say, "If you've harmed her, I'll make you pay" but you have harmed her! So there's that, I've got here too late. And whatever you're going through, if it doesn't kill you, I will hurt you until I feel better and I don't think I ever will! How cruel of me...

DOCTOR: What the hell are you doing!?

AMY: Changing the future. It's called marriage.

DOCTOR: Well, I must say, young man, I'm very proud of you.

STEVEN: Doctor, I don't know if I-

DOCTOR: I know, I know, my boy. Well, go on, you mustn't keep them waiting.

STEVEN: Goodbye, Doctor.

DOCTOR: Goodbye, Steven, and good luck.

(Steven leaves.)

DOCTOR: Fear makes companions of all of us.
