Act 1, Scene 3-4

Scene 3 marks the pivotal encounter between Macbeth, Banquo, and the three witches on the heath. The witches deliver their prophecies, addressing Macbeth as Thane of Glamis and future king. Banquo is told his descendants will be kings, though he will not. As the witches vanish, Ross and Angus arrive to confirm part of the prophecy, naming Macbeth as the new Thane of Cawdor.

In Scene 4, we see the first seeds of Macbeth's ambition taking root. At Duncan's palace in Forres, the king praises Macbeth's loyalty and names his son Malcolm as heir. This announcement conflicts with Macbeth's newfound aspirations, though he hides his disappointment.

Quote: "The Prince of Cumberland! That is a step / On which I must fall down, or else o'erleap, / For in my way it lies." - Macbeth, revealing his ambition and the conflict it creates.

Highlight: Shakespeare uses imagery of growth and fertility in this scene, creating irony given the murderous thoughts beginning to form in Macbeth's mind.

Scene 5-6: Lady Macbeth's Introduction

Lady Macbeth emerges as a crucial character upon receiving Macbeth's letter about the prophecies. She immediately begins plotting Duncan's murder when she learns of his impending visit to their castle at Inverness.

Quote: "Look like the innocent flower, but be the serpent under it"

Highlight: Lady Macbeth's character reveals her ambitious and manipulative nature
