How does Miles indicate those who were involved in the hazing incident in "one hundred twenty-six days before"?

Chip asks Miles to point out which of the other students had been involved in the taping-and-tossing incident the night before. In World Religions, Miles points out a boy named Kevin and another boy, and later, he points out a third. Chip tells him they're all Weekday Warriors, and the third boy is a friend of his girlfriend, Sara.
