Polonius sent his servant Reynaldo to Paris to give Laertes some money and letters, but also to secretly check up on him. Polonius’s instructions were so precise and complicated that they seemed absurd. Ophelia entered, upset. She told Polonius that Hamlet burst into her room and held her wrists, staring at her face and sighing. Then he left without saying anything.
Polonius came to the conclusion that Hamlet was going mad with love because he ordered Ophelia to stop speaking with him.
