What leads up to the death scene and how does it play out?

The Player says that he can provide any death the audience wants whether it is by hanging, convulsion, stabbing, poison, or whatever is wanted. Then he commands his troupe to die. Alfred, who is still in his costume, appears to die by poison. The Player pretends to fight with the troupe member dressed as the King, and they are both wounded. The two remaining tragedians are dressed as Rosencrantz and Guildenstern and are stabbed.
