You Can't Trick A Trickster

Hamlet as a trickster throughout the play i believe catches on that he is being watched during the end of his soliloquy in Act 3 Scene 1.  Since Hamlet is alone at the beginning of his soliloquy he is just expressing his thoughts to the audience, which by definition is a soliloquy.  At this point he is unaware that he is being watched, but when Ophelia enters the room he clues in that the king as sent for him here but is nowhere to be found and now that Ophelia enters he now has to question where Claudius and Polonius are by asking Ophelia “Where’s your father?” (III. i. 130-131).  Hamlet also may clue in to the fact that he knows the king sent Rosencrantz and Guildenstern to spy on him throughout the play so why wouldn't they be spying on him now?  In my opinion Hamlet may not know for sure he is being watched but when he figures out all the clues that he might be he puts on his crazy act just to make sure nobody figures out his plot.

Hamlet's most famous soliloquy shows that he is a very intelligent individual who is always thinking of his next move.  He often may doubt some of his decisions but never backs down in the long run even if it causes him to procrastinate.  His first five lines in the Soliloquy say it all “To be, or not to be, … Or to take arms against a sea of troubles And by opposing end them.” (III. i. 56-60).  These first five lines are him asking himself if he is really doing the right thing be getting revenge on his uncle.  This also proves the reasons why Hamlet is known to be procrastinator, Hamlet is unaware of what he truly desires and if two wrongs really do make a right when it comes down to it.  

The mood from this scene brings out Hamlets true emotions over Claudius and Ophelia.  When Hamlet enters the scene by himself I believe he enters with confusion over not knowing what he is going to do next, but as he continues expressing his thought and sees Ophelia he becomes aware of how much he wants to get revenge back to his Uncle for stealing his father's life.  When he sees Ophelia i believe he becomes aware of his uncle and maybe others watching, since after all the king sent him here but is nowhere to be found.  This makes Hamlet start blaring out his “feelings” to Ophelia of what he wants his uncle to believe.  In this scene you can also tell how much Hamlet is in love with Ophelia because even though he is putting on an act he tries to drop somewhat hints to Ophelia by saying “Get thee to a nunnery” (III. i. 121) & “believe none of us. Go thy ways to a nunnery.” (III. i. 129-130).  By saying these things Hamlet is trying to tell Ophelia to believe nobody trying to hint that this all may be an act, but also telling her to go hid and be safe.  

After thoroughly observing the text I believed that Hamlet was his expressing his thoughts at the beginning of the soliloquy but caught on to the kings trick of luring him by the end when he witness’s Ophelia's beauty.

Re: Sam
I agree that it is hard to tell whether or not he is directing his soliloquy to an audience or just himself, but i disagree at how you think he was being watching the entire scene. If he was saying his most famous soliloquy to and audience then it wouldn't be a soliloquy at all, but this could also be why its the most famous because it is a soliloquy that keeps the audience thinking if he is aware or not that the King and Polonius are watching. Also like you said he has to have clued in the someone is watching him because the King has summoned him but only Ophelia shows up. So i agree that it is tough to judge when or if Hamlet realizes he is being watched.
