DOCTOR: The human race might be clever and bright and brilliant, it's also savage and venal and relentless. All the anger out there on the street - the lies, the righteousness - that's human, that's you. That's who you are. Using your intelligence to be stupid. Poisoning the world. And hating each other? You've never needed any help with that. But today, something else is using your worst attributes, playing with you like toys.
