Heroic couplet - at the end of a soliloquy, means a decision has been made,
- two lines in a iambic pentameter that rhyme
- Hear it not Duncan of it's a kneel, That summons thee to heaven, or to hell
"Not so happy, yet much happier!"
A foil is a character that follows the same story line as the protagonist, but makes different choices, and in Macbeth, this character is Banquo. He was told by the witches that he will have a great future like Macbeth, but he didn't do anything about it, he didn't plot a plan against his friends just to reach that future. He also chose not to take the information seriously even though the witches proved themselves trustworthy. And that's where their paths split apart.
