For scene three I would have fog constantly surrounding Macbeth. I would have Macbeth surrounded because it foreshadows the lack of clarity in his upcoming decisions. When the witches are with Macbeth some of the fog will move towards them as well. This is because the witches are still very mysterious. As soon as they vanish the fog will return to Macbeth. Macbeth exclaims “Would they have stayed!” after the witches vanish, wanting some understanding about these questionable beings.
