Another way Michael develops over the text is his increase in intelligence. When he enters Briarcrest, the school he attends throughout the book, "... the grade point average the boy would bring with him to Briarcrest began with a zero: 0.6" (Lewis 53). By the time he graduates, he has a 2.56 GPA. This change happens because the Touhy's provide Michael with a private tutor to help him understand what he is learning in school. This also happens as Michael learns how to learn in a classroom.The final way Michael develops is socially. Before attending being taken in by the Touhy's, Michael is afraid to talk with strangers and people he doesn't know very well. Being with the Touhy's and attending Briarcrest makes him better with other people and Michael soon becomes a very friendly person.
