The Archdeacon and Brother Labas with Baby Quasimodo
The Priests a.k.a unnamed Archdeacon and brother Labas (not sure of spelling), are the only people who appear to work at Notre Dame and are Quasimodo’s care givers. This means that Quasimodo has two dads.
Both of them fulfill the role of Frollo’s parental/priest roles from the book, though why there are two of them, I couldn’t tell you. If I had to venture a guess I would say it was more for comedy. The Archdeacon is more the less the straight-man to Lebas, though the aren’t exactly funny, except for the scene where Frollo is threatening the church for shinies. Other than that there was no need for Brother Lebas.
They aren’t wholly nice as they don’t give in to Frollo and the Archdeacon saves himself when he is arrested. For their roles they are fine, they are not the annoying and they don’t get in the way despite Brother Lebas being a superfluous character.
