Fitzgerald uses Jordan's story about Gatsby to contrast what we've already been told.... to show Gatsby from another perspective. Jordan portrays him as a romantic, forced to worship his lover from afar, and although she implies that there was something in Gatsby's background that caused Daisy's parents to oppose their marriage, it is clear that the young Jay Gatsby was a man of unimpeachable virtue. In using this perspective, Fitzgerald draws upon a few centuries of romantic cliché to present Gatsby as the ideal lover: a soldier going off to war, brave and handsome, young and pure.
