Julie Alexandra Mayer is the eldest child of Susan Delfino and Karl Mayer. Growing up, Julie was the perfect child for Susan; she was often seen as the mother in their relationship as she cooked, cleaned and even gave her mother dating advice. She seemed to be a happy child to others, but secretly her childhood had damaged her significantly, causing her to lose control in later life. She got involved with a “bad boy”, dropped out of medical school, slept with a married man and got pregnant accidentally with a friend.
