is quasimodo related to esmeralda?
Those “characters” are Quasimodo, Esmeralda, that little girl who hugs Quasimodo at the end and if you look REALLY closely Quasimodo's mother. Everyone else has black eyes including Phoebus and Frollo. ... I would say they are not siblings as Esmeralda was not with Quasimodo's parents when they tried to entered Paris.
