I am trying to understand how to connect Marie-Laures unusual origin and explain how it connects to her current relationships and at the same time how it connects to a universal theme. I wanted to talk about her blindness as her unusual orgin and talk about how it made her vulnerable, intrepid, and kind and how those impact her relationships with others and also connect it to the theme of the tragedy of war.... I wanted to make sure my thinking is making sense and would like a second opinion.
