How does brother Leon make the rest of the class suffer using Baily as bait

He makes Bailey go to the front of the classroom, and in front of everyone, Leon accuses Bailey of cheating. Leon wonders how else Bailey could always get such great grades. Bailey protests, saying that he does not cheat and never has, but Leon is relentless, accusing him then of lying as well as cheating. Leon gets Bailey to admit that he is not perfect, and twists his words to make it seem as if Bailey is then admitting to cheating. Jerry watches this exchange in horror and finally someone says to leave him alone. The bell rings, and Brother Leon asks them all to wait a minute. He then compliments Bailey on his bravery, and berates the students for watching the exchange and for enjoying it. Leon turns the tables, saying that the others were really the cheaters because they doubted Bailey.
