Question

"Who is the speaker? Banquo

Who is the ""thou"" being referred to in the first line? Macbeth

What is the speaker explaining?
Banquo says Macbeth now has everything stated in the witches' prophesies but he believes Macbeth killed to get it all. Then he remembers that the witches said that Macbeth would not have an heir to the throne."

Answer 1

Banquo, in Shakespeare's 'Macbeth', speculates that Macbeth may have achieved the witches' prophecies through foul means and remembers that while Macbeth becomes king, Banquo's descendants are to inherit the throne.

Step-by-step explanation:

The question relates to the character Banquo in Shakespeare’s play "Macbeth". Banquo is suspicious of the circumstances under which Macbeth has risen to power. His speculation stems from the witches’ prophecies, which foretold that Macbeth would become Thane of Cawdor and eventually the king. Banquo recalls that the witches also predicted that while Macbeth would be king, it would be Banquo’s descendants who would inherit the throne, not Macbeth’s. This leads Banquo to believe that Macbeth might have had a hand in fulfilling the witches' prophecies through foul play.
