"We will do our best." [Lancelot]
"Long ago when I had Merlyn to help, he tried to teach me to think. He knew he would have to leave in the end, so he forced me to think for myself. Don't ever let anybody teach you to think, Lance: it is the curse of the world." The king sat looking at his fingers, and they waited while the old thoughts ran sideways across his hands like crabs.
