Act Three
Rosencrantz and Guildenstern find themselves on a ship that has already set sail. The pair seems to have no knowledge of how they got there. At first, they try to determine whether they are still alive, before they recognize that they are not dead and are on board a boat. They remember that Claudius has given them a letter to deliver to England. After some brief confusion over who actually has the letter, they find it and eventually open it. They realize that Claudius has asked for Hamlet to be killed. While Rosencrantz seems hesitant to follow their orders now, Guildenstern convinces him that they are not worthy of interfering with fate and the plans of kings. The stage darkens and, presumably, the characters go to sleep. Hamlet switches the letter with one he has written himself, an act which takes place offstage in Hamlet.
The pair discovers that the Tragedians are hidden ("impossibly", according to the stage directions) in several barrels on deck. They are fleeing Denmark because their play offended Claudius. When Rosencrantz complains that there is not enough action, pirates attack. Hamlet, Rosencrantz, Guildenstern, and the Player all hide in separate barrels. The lights dim.
When the lights come on again, Hamlet has vanished (in Hamlet it is reported that he was kidnapped by pirates from the ship). Rosencrantz and Guildenstern panic, then re-read the letter to find that it now calls for them to be put to death instead of the prince. Guildenstern cannot understand why he and Rosencrantz are so important as to necessitate their executions.
The Player tells Guildenstern that all paths end in death. Guildenstern snaps and draws the Player's dagger from his belt, shouting that his portrayals of death do not do justice to the real thing. He stabs the Player and the Player appears to die. Guildenstern fully believes that he has killed the Player. Seconds later, the Tragedians begin to clap and the Player stands up and bows, revealing the knife to be a theatrical one with a retractable blade. The Tragedians then act out the deaths from the final scene of Hamlet.
The lighting shifts so that Rosencrantz and Guildenstern appear alone. Rosencrantz still does not understand why they must die, yet he resigns himself to his fate and he disappears. Guildenstern wonders when he passed the point where he could have stopped the series of events that has brought him to this point. He disappears as well. The final scene features the last few lines from Shakespeare's Hamlet, as the Ambassador from England announces that Rosencrantz and Guildenstern are dead.
