What are some scenes with foreshadowing in Walk Two Moons?

There are several instances of foreshadowing in the first chapter and some teasers that actually mislead the reader to some degree. Sal says “peculiar” things happen to Phoebe and that Sal’s own story is hidden beneath Phoebe’s. Sal explains that she and her parents lived in an old farmhouse they were restoring together until her mother left them “one April morning.” Sal’s mother’s name was Chanhassen Pickford Hiddle but everyone called her “Sugar.” Soon after Sugar’s departure, Sal’s father begins chipping away at the plaster on a particular wall in the house. Sal says that one day they learn that her mother is not going to return home at all. That’s the day her father attacks the wall and discovers there’s a fireplace hidden behind the plaster. This is an analogy for the hidden story of Sal’s family that is very similar in some ways to the story of Phoebe’s family

In Chapter 13, Ben makes an interesting comment that’s a foreshadowing of his own story. He knows that Phoebe is referring to Mike as “a potential lunatic.” Ben says Phoebe and Sal shouldn’t call the young man a lunatic. He seems to be trying to say that it isn’t nice but gives up trying to explain. Sal will later learn that Ben’s mother is in an asylum and has obviously had some sort of nervous breakdown.
