Poor Hugo. In The invention of Hugo Cabret, he doesn’t have the best track record with family; after all, he’s orphaned and his Uncle Claude was a real jerk, if we do say so ourselves. He’s pretty much got no one left when we meet him, which is very sad for a little boy who should be in school and getting proper nutritional lunches without having to steal. You could say that Isabelle doesn’t have a family either… except she has Papa Georges and Mama Jeanne, who are her godparents and care for her as their own child. And when Hugo comes across their motley little family unit, somehow he becomes a part of it all too.
Hugo is isolated because he has no family and doesn’t know whom to turn to in the train station.
Even though Isabelle is orphaned, she still has a loving family, and that is something that Hugo envies.
