How does chapter 5 of Frankenstein by Mary Shelley prepare the reader for what happens in the story?

In chapter 5, the monster receives life and it literally
makes Victor physically sick. Throughout the rest of the book, Victor spends much time
contemplating the consequences of his action and suffers intense mental anguish for this
creation. The monster is gone by the middle of the chapter and that leaves the reader
hanging in suspense about what will become of the monster because there are 21 chapters
to go! Henry, Victor Frankenstein's good childhood friend arrives on the scene and in
this chapter Victor most worries himself about what will become of his poor friend if
the monster finds Henry. Fortunately that never happens in this chapter, but the fear
and worry certainly foreshadows the fact that Victor's family and friends will encounter
significant consequence because of Victor's action.
