What would Jim Nightshade be as a symbol?

Jim was born one minute after midnight on October 31st (Halloween). He is thirteen years old at the start of the novel. Of the two friends in the book, Jim is dark, brooding, more impulsive and impatient compared to Will. He wants to know everything and is obsessed with the idea of growing up. Consider the carousel as your symbol. The carousel, with its ability to make people older, therefore holds special sway over Jim throughout the course of the novel. In the novel's climax, he rides the carousel for one-and-a-half rotations, aging a corresponding one-and-a-half years. By the end of the book, however, Jim begins to accept his age and the limitations - and joys - that come with it.
