According to convention, the inclusion of the Savage Reservation should blur the clarity of the world of London. But Huxley manages to bring his dystopia into even sharper focus with the trip to the Savage Reservation. Both worlds emerge as believable and horrifying, each in its own way.
By holding the introduction of his main character until the middle of the novel, Huxley also flouts narrative convention. In this, Huxley uses the reader's expectations about structure to produce a particular effect. Since convention dictates that the main character appear very early in the novel, readers frequently become convinced that Bernard Marx will be at the center of the plot and theme. Just when Bernard proves himself cowardly and weak, despite his rebelliousness, Huxley offers John, the real main character.
Compared to Bernard, John appears truly heroic, at least initially, and, as a "savage," introduces a new perspective that Huxley uses upon the return to London. In bringing John into a dystopia already familiar to the reader, Huxley can play the reader's knowledge against the character's innocence. And the effect of this irony — Huxley's strong point — intensifies the climax and conclusion of Brave New World.
