King Claudius plans his next step when he discovers Polonius' death. Thinking it would've been him if he weren't so careful, he orders Rosencrantz and Guildenstern to go find Hamlet and Polonius' body.
Hamlet enters and tells Rosencrantz how he is a sponge that soaks up the King's demands so he can squeeze it out and throw him away afterwards. Ouch!
Hamlet sasses Claudius by lecturing him instead of revealing where Polonius' body is. He tells Claudius about death being the great equalizer and how everyone is food for worms in the end.
Hamlet says he should check heaven by sending a servant but check hell himself. Translation: GO TO HELL
This attitude definitely convinced Claudius to have Hamlet killed in England. Will he succeed?
