Judy Jones is a static character because she does not undergo any sort of character development throughout the story.
From the begining to the end of the story, she is shown as a very selfish, spoiled and superficial person.
She believes that, because she is the most beautiful, she should be the heppiest person. For her, money and status are the only things that matter.
