CY: Doctor, I’m pointing a blaster at you. And I’m about to steal your ship. Aren’t you angry?

DOCTOR: Would it make you feel better if I were angry?

CY: Make me feel better? What are you talking about?

DOCTOR: Sometimes, when people do a bad thing they know is bad, they feel better about having done it if the party they’ve wronged reacts angrily. Maybe you wanted me to be angry with you, so you could feel better about having stolen my ship. Because you could convince yourself I wasn’t a nice person, or that I might have done the same to you. You see?
