In I.iii, the Witches appear again. They talk about using their powers on humans, and it becomes clear that they have a lot of power, but they cannot kill people. Macbeth and Banquo are returning from the battlefield to Forres, and meet the witches. Banquo is amazed by the way the witches look, because they look like women but they have beards. Macbeth is not afraid and asks them what they are. They do not answer him, but greet him as the Thane of Glamis, the Thane of Cawdor and the future King. Macbeth is surprised, because he knows that he is not the Thane of Cawdor, and does not think he will ever become the King. Banquo asks the witches what his future will be like. They answer in riddles, saying that he will be "lesser than Macbeth, and greater", "not so happy, yet much happier", and that he will be the father to a line of kings. Then the witches disappear.
