At his celebratory feast, Macbeth receives word from one of the murderers that Banquo has been killed. While he is distressed that Fleance escaped, the new King of Scotland is in fairly high spirits. When he goes to sit down, however, Macbeth sees the ghost of Banquo sitting in his seat. Naturally, Macbeth is troubled and begins talking to this apparition, worrying his guests. This scene exemplifies Macbeth's paranoia and anxiety that accompany the killing of his countrymen in order to obtain power.
Please, do not worry. My husband frequently has fits such as these. It is merely a condition he has had since childhood.
What? Speak to me if you can. No, why should I care? You are dead and have no power over me. Be gone, foul spirit!
The witches meet to discuss the happenings so far when they are met by Hecate, the goddess of witchcraft and the source of their power. She reprimands the witches for meddling in the affairs of mortals without inviting her to show off her own powers. Hecate then, however, predicts the downfall of Macbeth, claiming that he will be fooled into thinking he is greater than fate before falling prey to his own overconfidence. From this point on, the reader is aware that Macbeth will have a tragic end.
How dare you begin meddling with Macbeth without consulting me? Do not forget that I am the source of your powers! I will make him mock death before he succumbs to his own overconfidence.
Two noblemen meet to discuss their suspicions regarding Macbeth's latest actions. While neither man says it outright, the reader can judge by their conversation that each individual believes that their new king may have had a hand in the murders of Duncan and Banquo. Additionally, through this conversation the reader learns that Macduff has fled to England in an attempt to get the help of the British King. Clearly, the everyday Scottish citizen is not a loyal supporter of Macbeth.
I am suspicious of Macbeth. Even though he claimed he was loyal to Duncan, these foul events reek of his treachery.
Yes, I am, too. You better pray no one hears you say that. Keep your tongue sharp to avoid drawing suspicion yourself. I have heard that Macduff has fled to England to enlist the help of King Edward. Hopefully we can throw off this tyrant!
