Act II.
Polonius tells Reynaldo to spy on his son Laertes in Paris. Polonius learns from his daughter Ophelia that a badly dressed Hamlet met her, studied her face and promptly left. Polonius believes that Hamlet's odd behaviour is because Ophelia has rejected him. Polonius decides to tell King Claudius the reason for Hamlet's recently odd behaviour.
King Claudius instructs courtiers Rosencrantz and Guildenstern to find out what is causing Hamlet's strange "transformation," or change of character. Queen Gertrude reveals that only King Hamlet's death and her recent remarriage could be upsetting Hamlet.
We learn more of Young Fortinbras' movements and Polonius has his own theory about Hamlet's transformation; it is caused by Hamlet's love for his daughter Ophelia. Hamlet makes his famous speech about the greatness of man. Hamlet plans to use a play to test if King Claudius really did kill his father as King Hamlet's Ghost told him...
