what is the development of a dynamic character in chapter 8?(any character)

Wilson seems to be Gatsby's grim double in Chapter VIII, and represents the more menacing aspects of a capacity for visionary dreaming. Like Gatsby, he fundamentally alters the course of his life by attaching symbolic significance to something that is, in and of itself, meaningless. For Gatsby, it is Daisy and her green light, for Wilson, it is the eyes of Dr. T.J. Eckleburg. Both men are destroyed by their love of women who love the brutal Tom Buchanan; both are consumed with longing for something greater than themselves. While Gatsby is a "successful" American dreamer (at least insofar as he has realized his dreams of wealth), Wilson exemplifies the fate of the failed dreamer, whose poverty has deprived him of even his ability to hope.
