Claudius believes that Hamlet is becoming more and more crazy. Fearing the risk of danger, he asks Rosencrantz and Guildenstern to go to England with Hamlet.
You must go to England with him, because I cannot risk the chance of danger!
We will take care of it! It is our duty to serve Your Highness.
Polonius comes to tell Claudius that he is going to spy on Gertrude and Hamlet's conversation, thinking it is wise to have someone other than a mother listening.
I will hide behind the tapestry in Gertrude's room to hear the conversation between her and Hamlet.
Hamlet catches Claudius vainly trying to pray. He decides not to kill him then, because since he was in the act of prayer, he would go to heaven. Hamlet decides to wait and kill Claudius while he is committing a sinful act.
I could do it so easily right now. But I cannot, he is professing his sins!
My soul is stuck to sin...
Help! Someone help!
What are you going to do? You won't kill me, will you? Help!
What is this, a rat? A dead rat now.
A horrible act—almost as bad, my good mother, as killing a king and marrying his brother.
This is only a figment of your imagination. Madness is good at creating hallucinations.
As Gertrude fears for her life, Polonius calls for help from behind the tapestry. Hamlet hears him and charges toward him.
Oh, what a senseless, horrible act!
Hamlet hears Polonius's cries from behind the tapestry and stabs through it, killing him. Gertrude was appalled, and could not believe what Hamlet had done.
King Hamlet's ghost enters and reminds Hamlet of his mission to get revenge on Claudius. Gertrude thinks Hamlet has gone mad, as she cannot see the ghost. Hamlet tries to convince his mother that he has been feigning madness, and makes her swear to keep his secret.
