How are Gene and Phineas foils in terms of conformity?

Gene and Finny are definitely foils in terms of this particular theme, and actually act as foils to each other throughout the novel. In terms of conformity, Gene is a rule follower. He likes order, and he does what is expected of him. Finny, however, is Gene's polar opposite. He is a rebel, and rules mean nothing to him..... except as something to break.
