How does Hemingway come between Zelda and Scott in the novel, Z: A Novel of Zelda Fitzgerald?

Hemingway is an important character for the devastation he causes within Scott and Zelda’s relationship. Hemingway continuously tries to convince Scott that Zelda is bad for him, and even goes as far to spread gossip that Zelda is mentally insane. Though Zelda tries to warn Scott that Hemingway is not a good man, time and time again Scott refuses to listen to her. Hemingway’s ultimate goal is to replace Zelda and gain control over Scott, which leads her to fear that the two are having a sexual affair. Though Zelda concludes that the romantic love between Hemingway and Scott is one sided on Hemingway’s part, she nonetheless notes that Scott was “obsessing over Ernest Hemingway” (234), in a way that he once did with her. Even after the couple moves away from Paris, Hemingway manages to periodically creep back into Zelda’s life. It is only after Scott’s death that Zelda can distance herself from Hemingway, who turns to slandering the Fitzgeralds once Scott’s death brings him into literary fame.
