Jack Jardine’s eighteen-year-old son. Jack Jr. and his unnamed friend destroy América and Cándido’s camp in the canyon and graffiti it with the words “Beaners Die.” Jack Jr. also tells racist jokes, and is responsible for spray painting the wall surrounding Arroyo Blanco Estates, presumably to stoke tension between the community and the immigrants he knows will take the blame. Only Delaney knows that Jack Jr. is the one to have spray painted the wall, and he deliberately hides the evidence of this from his neighbors. Throughout the novel, América and Cándido operate under the belief that Jack Jr. is actually Delaney’s son.
