How does the author use foreshadowing in The Life and Adventures of Nicholas Nickleby?

In Part I, Act I, Nichloas' passion for honesty and acting/speaking impulsively gets him into trouble, something that foreshadows events at the end of this act and throughout the rest of the play. We also see the beginnings of deeper feeling, particularly compassion for Smike. This section, in fact, marks the true beginning of Nicholas' journey of transformation. He's already begun the journey through the events of his life. In this section, his journey towards true maturity begins. This manifests at this point in his growing compassion for Smike and resentment about how he's treated.
