DOCTOR: Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.

BILL: If you care so much, tell me how many people you’ve seen die?

DOCTOR: I don’t know.

BILL: Yeah? How many before you lost count?

DOCTOR: I care, Bill, but I move on.

DOCTOR: I am two thousand years old and I have never had the time for the luxury of outrage.

DOCTOR: What’s wrong?

BILL: What’s wrong? Seriously, what’s wrong? I’ve never seen anyone die before.

DOCTOR: A few hours ago, we were standing in a garden full of dead people.

BILL: That was different.

DOCTOR: How?

BILL: They were dead already.

DOCTOR: Morally and practically, that is not a useful distinction. Unlearn it.

BILL: Don’t tell me what to think.

DOCTOR: I’m your teacher. Telling you things is what I do.

BILL: Yeah? Tell me this. You’ve seen people die before, yeah?

DOCTOR: Of course.

BILL: You still care?

DOCTOR: Of course I care.

BILL: How many?

DOCTOR: How many what?

BILL: If you care so much, tell me how many people you’ve seen die?

DOCTOR: I don’t know.

BILL: Okay. How many before you lost count?

DOCTOR: I care, Bill, but I move on.

BILL: Yeah? How quickly?

DOCTOR: It’s not me you’re angry with.

BILL: Have you ever killed anyone? There’s a look in your eyes sometimes that makes me wonder. Have you?

DOCTOR: There are situations when the options available are limited.

BILL: Not what I asked.

DOCTOR: Sometimes the choices are very

BILL: That’s not what I asked!

DOCTOR: Yes.

BILL: How many?

(No reply.)

BILL: Don’t tell me. You’ve moved on.

DOCTOR: You know what happens if I don’t move on? More people die. There are kids living rough near here. They may well be next on the menu. Do you want to help me? Do you want to stand here stamping your foot? Because let me tell you something. I’m two thousand years old, and I have never had the time for the luxury of outrage.
