How does the author use foreshadowing in The Day They Came to Arrest the Book?

Chapter Three introduces two of the novel's main plotlines.... those of the apparent racism seen by some within the novel Huckleberry Finn, and the silent censorship occurring at the hands of Principal Moore in the high school. Gordon's anger and outrage at the repeated word "nigger" in the book, and his revelation that his father has a conference with Principal Moore, when combined with the knowledge of Moore's censorship activities, foreshadows events to come as Huckleberry Finn comes under scrutiny.
