Jehan is Claude Frollo’s younger brother and a student at the University in Paris. Jehan is adopted by Frollo at a young age, after their parents die from the plague. Although Frollo provides the best possible education for Jehan, Jehan squanders his time at university and spends all his money drinking and visiting prostitutes. Jehan is notorious for his involvement in many brawls on campus and does not respect Frollo, despite the many sacrifices Frollo has made for him. Instead, Jehan believes his older brother is mad and foolish and only visits him when he wants money. Like Frollo, however, Jehan is prone to extreme emotions and is very impulsive. While Frollo represses this side of himself, Jehan gives in to all his emotions and sensual urges and does so with relish. He loves pleasure and wants to live a life of debauchery. This is demonstrated when Jehan finally decides to give up his respectable education for good and become a “truant.” Jehan’s extreme personality and impulsive nature are eventually his downfall when he joins the riot against Notre Dame and throws himself into the fighting. He is killed by Quasimodo, who defends the cathedral during this riot.
