Osric brings the swords, and Laertes makes a show of choosing his; Hamlet asks only if the one he has chosen is the same length as the others. The King sets wine out for the duelists to drink and holds up the cup intended for Hamlet. Laertes and Hamlet fence for a moment until Hamlet asks for a judgment call from Osric the referee. Osric proclaims a hit in Hamlet's favor, and Claudius holds up Hamlet's goblet and takes a drink. With high pomp, Claudius drops a pearl, his gift to Hamlet, into the wine.
When Hamlet hits Laertes a second time, Laertes protests that it is a mere touch. Claudius assures Gertrude that, "Our son shall win." Gertrude agrees. She takes Hamlet's wine, wipes his brow, and offers him a drink, which he refuses. She then toasts her son. Claudius asks her not to drink, but she does and then wipes Hamlet's brow one more time.
Laertes tells Claudius that the time has come to hit Hamlet with the poisoned tip. Claudius disagrees. In an aside, Laertes expresses a reluctance to hit Hamlet, but Hamlet accuses him of dallying and presses for a third bout. The two fight again and Laertes wounds Hamlet with the poisoned tip. Both drop their swords and, in the scuffle, Hamlet grabs Laertes' sword and Laertes picks up Hamlet's. Hamlet hits Laertes with the poisoned sword. Gertrude swoons. Hamlet sees the Queen fall and anxiously asks, "How does the Queen?" The King assures him that she is faint because of the blood, but Gertrude cries out that the drink has poisoned her. Outraged, Hamlet orders the doors locked so that the King cannot escape. Laertes reveals the murder plot to Hamlet and explains that the poisoned sword now rests in Hamlet's hands.
