Well, after reading this act, I'd think twice about spending a night at Macbeth's castle. Sure, the hospitality is fine, food is great, and there's even a room for your bodyguards to hang out. But there are ghostly daggers floating, and watch out for that late night drink...
The opening of Act 2 shows how Macbeth is thought of as a good person, loyal soldier and all-around good guy. Banquo, Macbeth's best friend, tells our anti-hero that King Duncan has not only rewarded Macbeth with a promotion to Thane of Cawdor, but also given MacB a big diamond for his Lady. Banquo is still troubled by what the Weird Sisters said, but Macbeth says he never thinks about it.
Do you believe him?
When Banquo leaves, Macbeth sees a ghostly dagger, pointing the way to Duncan's chamber. Where did this come from? Is it a "dagger of the mind, a false creation/proceeding from the heat-oppressed brain?" Or, is this some supernatural vision, sent by supernatural powers to prod Macbeth to murder?
Macbeth alludes to the presence of witchcraft in this passage. Is he acting on his own, or are there other forces propelling him to kill Duncan?
After Duncan's murder, Macbeth is so shaken up that he forgets to leave the dagger behind. It's part of the big frame-up, and Lady Macbeth is a little upset with him.
Men. You can't get them to follow the simplest of directions.
Now Lady Macbeth has blood on her hands, literally and figuratively.
She realizes that her husband is going to have to do some pretty good acting to cover themselves. What does she tell Macbeth to do? What does Lady Macbeth do to further increase the dramatic reactions to Duncan's death?
Scene iii shows another example of Shakepearean wordplay. It's interesting how Shakespeare uses minor character to provide some comic relief in this scene, while staying true to the plot and overall tone of the work. See if you can find specific examples of this in the drunken porter's dialogue.
