I've already trod on dangerous ground. We're on dangerous ground right now, because of our secrets and our lies. They're practically what define us. When the truth offends, we lie and lie until we can no longer remember it is even there. But it is...still there. Every lie we tell incurs a debt to the truth. Sooner or later, that debt is paid. That is how...an RBMK reactor core explodes: Lies.
