The next knight to arrive at Camelot is Sir Aglovale, the son of King Pellinore and his wife Piggy. He is in mourning for the death of his father, who was killed by the Orkney brothers for killing their mother, though the brothers also killed Aglovale’s brother Lamorak for sleeping with their mother. Aglovale is a young man bent on revenge, as is his right he believes. Arthur begs him to rethink the whole topic of revenge, which never comes to an end. Aglovale tells Arthur and Guenever that his mother died from grief, not long after his father. He tells of the adventures of Sir Percivale, his brother, who is as pious and pure as Sir Galahad. Aglovale’s sister had become a nun, cutting off her hair and saving it in a box. She joins Galahad, Percivale, and Sir Bors on a boat, where they find the sword of King David, which is given to Galahad, and two lesser swords for the other two knights. With spindles she finds on the boat, Aglovale’s sister spins a girdle out of her own hair. They sail to Carlisle, where they encounter a woman whose disease can be cured only by the blood of a maid of royal ancestry. Aglovale’s sister offers her blood, but she dies in the process. She is put in the boat, along with a letter explaining what happened, and set out into the ocean. Aglovale asks Arthur to invite the Orkney brothers to have dinner with him the following day.

The other knights continue to trickle back in to Camelot. The older knights, such as Sir Ector and Sir Grummore, survive, but the list of the dead continues to grow. It is rumored that Lancelot is among the dead, the victim of a fight with his son, Sir Galahad. But one day Lancelot comes home in a rainstorm. He is clad in scarlet and white, but underneath he wears a hair shirt. He goes straight to bed, tended to by Uncle Dap, who delivers a message to the king: The Grail has been found by Galahad, Percivale, and Bors, but it is being taken to Sarras in Babylon, along with the body of Percivale’s sister, because it can never be brought to Camelot. Bors would be coming home eventually, but the others would never return.

The next day, Lancelot tells Arthur and Guenever of his adventure. He had jousted with Galahad and been knocked down. As he lay there, a woman approached and said, “God be with thee, the best knight in the world.” Lancelot looked up to see who was talking to him but discovered that she was talking to Galahad. Lancelot then went to a chapel to confess but found it locked. He slept outside and in the morning he found that his weapons were gone. He sought out a hermit and confessed his sin. Thinking that he had been cleansed, he fought Galahad but was again defeated. He then found another hermit and confessed to the sin of pride. He was again defeated in the third joust, but now understood that victory was intentionally being withheld from him.
