How does the author use foreshadowing in The Rover?

In Act I, Scene II, there are several important moments of foreshadowing. Blunt's comment about being robbed by prostitutes, Frederick's comment that he hopes Lucetta will teach Blunt a lesson, and Belvile's reference to Blunt carrying their money all foreshadow what will happen later in the play when Blunt is, in fact, robbed by Lucetta. Also, the way Belvile refers to Willmore as a rover foreshadows the way his attentions move, or "rove", back and forth between Hellena and Angellica.
