Jane G. Alexander was smart. Her parents, on the other hand, were not. Well, Mr. Alexander was smart enough to cheat on the college entrance exams to Harvard, and Mrs. Alexander was smart enough to marry Mr. Alexander. Unfortunately, they weren't smart enough to read the fine print. But we'll get right to that later.
Jane was not happy at all. Her mother was constantly forgetting Jane's name, and her father seemed to think that the definition of love and affection was give the brat money and shut her up.
Jane and her parents had a bitter relationship from the start. Mrs. Alexander never wanted a baby, and Mr. Alexander wanted a boy. So, Mrs. Alexander did the most a married socialite could, and hired a nanny. Mr. Alexander did the best a former high school football quarterback cum elite business man could, and slept with the nanny. The nanny, of course, was named Esparanza and was better at the sleeping with Mr. Alexander then with putting little Jane to sleep.
How Jane G. Alexander became Aperture Science's youngest AI specialist is a mystery to everyone.
