In A Seperate Peace, how does Gene depend on Finny throughout the book?

THere is an almost creepy dynamic between these two. The central relationship in the novel—that between Finny and Gene—involves a complex dynamic of seeking to establish, yet being uncomfortable with, identity. Early in the book, the boys’ relationship seems fueled, in part, by Gene’s envy and resentment of his friend’s dominating spirit. As Finny demonstrates his physical prowess, Gene feels the need to accentuate his academic prowess. Finny’s fall from the tree, however, apparently purges Gene of his darker feelings and steers their relationship in a different direction so that codependency rather than envy characterizes it.
