In II.iii, the porter is very drunk. He pretends to be the porter of the gate of hell, and takes a long time to open the gate for Macduff and Lennox. Macbeth greets them. Macduff says that he is there to wake the king, and Macbeth leads him to the king's room. Macduff is shocked to see the king murdered on his bed. He runs out shouting and wakes everybody up. Macbeth pretends he did not know about the murder, as everyone comes to see what is happening. He admits that he killed the guards, and says that he did it because he was so angry that they killed Duncan. Lady Macbeth faints and they rush to help her. Malcolm and Donalbain think that somebody is lying. They know it is not safe for them to stay in Scotland, so they run away. Malcolm goes to England, and Donalbain to Ireland.
