How does the author use foreshadowing in Mao II?

In Chapter One, the reference to the homeless man, whose insistence upon not being touched foreshadows Bill's determination to remain "untouched" by the world, and Scott's visit to the library, with its references to Chairman Mao (which introduces the thematic presence of dictators). The reference to the portrait of Mao foreshadows the passing reference in Chapter Five to Scott giving Karen a copy of that same portrait, and introduces two repeated motifs ... the impact of faces (also commented upon in Brita's discussion of why she's photographing writers) and the idea of how dictators promote and build upon their power through image. Scott watching the young people playing on the skyscraper foreshadows the danger and risk, both physical and emotional, into which all four of the main characters place themselves throughout the narrative, while Brita's reference to meeting a "terrorist chief" introduces one of the book's primary themes, the likening of novel writing to terrorism.
