Help: HAMLET. ACT 2, SCENE 1: Help with characterization of Polonius from "Hamlet" and the foreshadowing motif that the scene displays.Please help...

Polonius is telling Reynaldo in this scene to spy on
Laertes.  Polonius tells him to ask people in Paris about what Danes are there, how much
money each has, where each lives, how each one conducts himself, etc.  Polonius says
that this method of asking general questions of no particular Dane will uncover more
information about Laertes.  Polonius continues, telling Reynaldo, to ask people if
they've heard of Laertes and if he's been known to hire prostitutes, gamble, get in fist
fights, and other activities.  Poloinus, despite his high-handed advice to his son in
Act, sc. 3, does not trust Laertes.  If he trusted him, Polonius would not send Reynaldo
to Paris to enact this elaborate scheme.  This action shows us that Polonius is not a
trusting man.  It also shows us that Polonius likes subterfuge.  He enjoys spying on
people and getting information about them without their knowledge.  This sneaky quality
is important because Polonius engages it in trying to find out what is going on with
Hamlet, too.  Never does Polonius suggest directly asking someone what he is up
to.
