Act 2, Scene 2

Claudius and Gertrude are worried about Hamlet, who’s been acting crazy in court, so they dispatch Rosencrantz and Guildenstern to spy on him. Polonius arrives with the ambassador Voltemand in tow, both bearing good news. Voltemand tells Claudius that the King of Norway has put a stop to Prince Fortinbras’ threats, and Fortinbras has vowed not to attack Denmark. Polonius then tells Gertrude and Claudius that he thinks Hamlet’s behavior is due to his feelings for Ophelia.
