He harms Magiano during the Daggers' and Roses' encounter in the arena while reviving Enzo, but Magiano isn't badly hurt. Leo later dies as a result of his poison turning on and harming himself from within. Raffaele is saddened by his death and he helps Raffaele realize that the Elites' bodies will finally turn on their owners.
