Julian and Max have been playing together at Hearst, but the former hates the latter's attitude to him and others as well as becoming football captain because of his father being the principal of Hearst. This enmity continued even after Julian's transfer to Berry High, when Max mocked Julian during a basketball match and falsely accused him of favoritism during baseball tryouts. Upon graduation and the revelation that Julian and Max will attend rival universities, the former laments that their rivalry will continue beyond high school.
