What are the motifs in The Moviegoer by Walker Percy?

Kate is John's cousin and one of the few people in the novel with whom John has a good relationship. Kate and John understand one another. Kate, however, suffers from extreme depression and is at odds with her world. Ironically, the source of her depression is her stepmother's vocal hope that she will improve. Aunt Emily — or Kate's stepmother — lives in Elysian Fields, which is a Greek reference to where all souls come to die. In order for Kate to accept the world that her stepmother is actively wishing she pursue, she would enter a form of Elysian Fields and kill her essence and soul within her to conform to the Southern New Orleans society.
