The scene starts with some rally loud knocking that wakes up the Porter of the castle angrily. After the death of King Duncan Shakespeare was to inflict some comedy for the play to not be dark. The Porter talks about lerchy, which means the excessive indulgence of sexual desire, to inflict some comedy to the play to cheer up the audience as a very spine-chilling death has just happened. As the Porter had waken up angrily he starts to call who ever is behind the door devil names for example Beelzebub, this shows that the Porter does not like to work in the castle because he barely gets any sleep so that shows that he likes to get all the  sleep he can get even if it is just a bit. Macbeth enters the scene trying to act as normal as he can. After Macduff had asked if the knocking had woken up the King,he goes and checks on the King and come back terrified as he had just found the bloody body of Duncan. Macbeth acts normal and externally tries to show that he is sorry so that people will not suspect anything” Had I died an hour before this chance, I had lived a blessed time” Macbeth says this in the external way that means that he wished he had died an hour before he ‘found out’ the death of Duncan as he did not want to experience this. Also Macbeth means this implicitly because he feels guilty of the death of Duncan, he wishes he had died an hour before he murdered him. At the end of the scene Macbeth tells everyone  how he had’ killed’ the guards because of his fury; furthermore after Macbeth leaves Malcom and Donaldbain discuss where they will flee.
