How does the author use foreshadowing in Mutation?

In Chapter Eight, Marsha, the child psychiatrist, presents an array of concerning information about VJ's behavior to Victor, who summarily dismisses her concerns. He insists VJ is a child prodigy and, therefore, beyond normal concerns. This type of character interaction is fully developed in the novel and presents a recurrent theme. Marsha's insistence is also a form of foreshadowing in that she is always presented as a credible professional.
