Neither Macbeth or Banquo expected that, and the witches banished, but then two men came and said that the Thane of Cawdor was a traitor and that Macbeth would have his title ! So he wrote a letter to his wife !
And you, Banquo, lesser than Macbeth, yet greater, not so happy, yet much happier, you shall beget kings, though you shall not be one
The king Duncan then came to the Macbeth's castle and Lady Macbeth wanted to kill him so that her husband would be king, they executed it, and they killed Duncan, something happened.
There was something that happened when Macbeth tried to kill King Duncan, he saw a dagger in front of him !
Is this a dagger that I see before me ?
The king Duncan was murdered by the Macbeth's, but even though they weren't caught, Macbeth was named king. He arranged a banquet, were Banquo was coming, so the king arranged 2 murderers to kill him, and his child so that he couldn't be overruled.
Macbeth, went again to the witches, thinking about the prophecies he sent 2 murderers to Macduff's castle and killed his son and wife.But meanwhile, Macduff was planning a war from England to Scotland to kill Macbeth.
Macbeth, beware of Macduff!
None born of a woman shall harm Macbeth!
Macbeth shouldn't be overruled unless Birnam woods begin to walk !
Here was the queen, and her assistant and her doctor, but she was rubbing her hands, this obviously meant that went she had the kings blood on her hands.
