The Once and Future King Book 3, Chapter 2
Lancelot is to become Arthur's greatest knight. He is not, however, the romantic figure that popular myth has made him out to be. He is fiercely devoted to Arthur's cause, and he is solitary and unhappy with himself. With the help of his uncle and personal aide, Uncle Dap, he works very hard for three years, even though he is so young, to be strong enough for Arthur. He also wants to be holy and good, because he thinks he is a terrible person. He wants to be able to heal people miraculously.
