The Once and Future King Book 3, Chapter 45
Things begin to improve at court again. Lancelot and Guenever are in love, and Arthur trusts them not to let him know it outright-because then, according to justice, he would have to punish them-and Arthur is inventing Law as Power. He is trying to end bullying and fighting altogether.
Lancelot still has not been able to do a miracle since he slept with Elaine. Then Sir Urre, a knight who has been cursed so that he will bleed continuously until he is healed by the best knight in the world, arrives. Arthur decides to let everyone else try before Lancelot, just in case. This tortures Lancelot-what if he fails? Then everyone will know his sin. Terrified, Lancelot comes forward-and cures the knight. Everyone cheers, and Lancelot alone recognizes that the real miracle is that he was allowed to do a miracle at all.
