Macbeth meets up with the witches, who are busy making potions and casting spells. He tells them he wants to learn more about his future. They tell him three key things: He should keep an eye on Macduff. He won’t face any harm from anyone “of woman born." He won’t be conquered until Birnam Wood marches to Dunsinane. Macbeth thinks this is all good news—after all, since when can forests march? And Macduff is definitely of woman born, right? Still, he thinks it’s a good idea to kill Macduff anyway, just in case. Everything seems to be working out well for Macbeth until the witches share with him one final vision: a long line of kings who all look just like Banquo. Once the witches depart, Lennox arrives to tell Macbeth that Macduff has gone to England. Since Macduff himself is out of reach, Macbeth opts to go after his family.
