Describe symbolism in Whatever Happened to Janie? by Caroline B. Cooney

In Chapter Eight, Jennie feels as though she and Janie were two different people. When the first exam is given to her, she struggles with what name to put at the top. At first, she just puts a 'J', symbolic of both names but then remembers what she and her parents had discussed. To keep them safe, she had to become Jennie. Deliberately and with great care, she wrote her birth name for the first time.
