Who does Fred Fairly meet on his way to his room? What is their conversation about?

Fred Fairly meets the Master of the College. The Master is blind, so, at first, he is unaware that it is Fred who is walking on the grass, which is a privilege reserved for the Fellows of the college. After Fred identifies himself as a Fellow, the Master asks him about his recent bicycle accident. The Master makes a comment that he hopes that Fred did not go to the hospital after the accident. Then he wants to know if Fred has made up his mind "about the most important question of all." Fred assumes the Master is referring to his religious beliefs, but he is told differently. At this point, the Senior Tutor takes charge of the Master, and Fred continues to his own room.
