Okay, so this sounds really cheesy, but Romero totally serves as a muse to those who can appreciate him. Montoya, Jake, and Brett all have a true understanding, whether learned or instinctive, of bull-fighting, and the three of them understand that Romero is something remarkable. Montoya and Jake both see that he is different from the other bull-fighters – he possesses a pure, genuine talent that stands out in a sport gradually being taken over by drama queens and fakes. Romero’s performances in the ring inspire Jake/Hemingway to write some of the novel’s most exuberant, vibrant, and passionate prose. Brett, the fledgling aficionado, is also inspired by Romero, but not to create art – he instead inspires true feeling in her. With Romero, we see Brett lose herself in passion for the first time in the book; instead of being the manipulator and enchantress of men, she is reduced to simply being a woman in love. He also inspires her to do the first and last decent(ish) thing she does in the novel – leave him. Brett realizes that she and Romero shouldn’t be together, and despite her feelings for him, she asks him to leave.
