"Can I just say, it's been an absolute pleasure to finally meet you?"
"I came because you're sick and you asked. And because sometimes, on a good day, if I try very hard, I'm not some old Time Lord who ran away. I'm the Doctor."
"Compassion then."
"Always."
"Why have I ever let you live?"
"Compassion, Doctor. It has always been your greatest indulgence. Let this be my final victory. Let me hear you say it, just once. Compassion is wrong."
