In Gertrude’s room, Polonius hides behind a tapestry. Hamlet’s entrance so alarms Gertrude that she cries out for help. Polonius echoes her cry, and Hamlet, thinking Polonius to be Claudius, stabs him to death. Hamlet then verbally attacks his mother for marrying Claudius. In the middle of Hamlet’s attack, the Ghost returns to remind Hamlet that his real purpose is to avenge his father’s death. Gertrude cannot see the Ghost and pities Hamlet’s apparent madness. After the Ghost exits, Hamlet urges Gertrude to abandon Claudius’s bed. He then tells her about Claudius’s plan to send him to England and reveals his suspicions that the journey is a plot against him, which he resolves to counter violently. He exits dragging out Polonius’s body.
