How does the author use foreshadowing in As Bees in Honey Drown?

In Act I, Scene IV, Beane illustrates how Wyler becomes more deeply involved with Alexa at the same time as Alexa's stories and schemes are also becoming more involved. Several elements of foreshadowing appear in this scene, including the reference to Wyler's notebook. The notebook plays an important role in his creation of art at the end of Act II.
