From the display in the ending scene, it is clear that Armand had a very negative perception of people with black ancestry (Chopin, 1893). His reaction is based on the fact that he does not value the people with black ancestry, meaning he does not value himself. He is in denial that he has been disregarding what he is. I would have made Armand feel the challenge of not being wanted by society. The challenge of trying to fit in a society that does not value blacks. I would have introduced a scene where he is chased away from a place and denied access to basic commodities. All these just to help him understand the burden of being rejected by society.
After the scene, I would picture Armand in a lonely place where he thinks of how life was before he discovers that he had black ancestry. Afterward, I would make him accept that his discovery that he has black ancestry changes nothing but makes him understand that all are equal and all races are entitled to the fact that they have to lead a life as everyone does. Accepting that all races are equal would make him rethink his take on blacks. Additionally, I would make Armand act as a fighter against racism in society. As he has a taste of both races, he can make a good character in the fight against racism. All the reactions would be reactions of a changed man who knows how it feels to treat others badly, where there is no gain, and be treated as such.
