Elsewhere in the castle, Lady Macbeth expresses despair and sends a servant to fetch her husband. Macbeth enters and tells his wife that he too is discontented, saying that his mind is "full of scorpions" (3.2.37). He feels that the business that they began by killing Duncan is not yet complete because there are still threats to the throne that must be eliminated. Macbeth tells his wife that he has planned "a deed of dreadful note" for Banquo and Fleance and urges her to be jovial and kind to Banquo during the evening's feast, in order to lure their next victim into a false sense of security (3.2.45).
