Freddie Lewis, Fourth Grader:

Lonely in a way with which Patty is uniquely familiar, Freddie is the introverted smart kid in a class full of boys and girls more interested in sports and socializing then studies. Small even for fourth grade, his self-imposed isolation is born both out of discomfort with his peers and concern for his many allergies. Finding a friend in Patty and sharing her interest in medicine, Freddie soon becomes her self-proclaimed assistant, shadowing her every move in his overlarge lab coat. Can Patty help him escape his shell?
