Claudio says: "and you must put me in your heart as a friend, if you have heard, and with a trained ear, that he who killed your noble father has haunted my life. "(IV;vii;1-4). This suggests Laertes to ally against Hamlet. Claudius thinks of a plan to kill Hamlet in a way that will make them both appear innocent. He states to Laertes "a dull sword, and, in a passage of practice, repay him for thy father" (4.7.135-137). This means that Claudius wants Laertes to duel Hamlet with a sharp pointed sword and not with a slanted sword for safety during the duel. Laertes agrees, but will also put poison on the tip of the sword so that the slightest scratch will cause Hamlet to die: "I will do it and for this I will anoint my sword. I bought an anointing from a charlatan, so deadly that, but by dipping a knife into it, where it drowns blood, no poultice so rare, collected by all the simple who have virtue under the moon, can save from death what is only scratched."(4.7.138 -144). While Laertes and Hamlet duel, both are wounded with the poisoned sword, when they realize that they will soon die the truth is revealed. Laertes tells Hamlet of the plan he had with Claudius and forgives him for his death
