What happens in Act 2, Scene 3: The Discovery of the King's Murder.
A porter answers the gate in a comic scene full of dark jokes, letting in Macduff and Lennox. Macbeth greets them. Macduff goes to wake Duncan and returns in horror: the king is dead. Macbeth and Lady Macbeth perform shock and grief. Macbeth admits he killed the guards in a rage, claiming he could not control himself when he saw them next to Duncan's body. Lady Macbeth faints, possibly to distract from Macbeth's suspicious explanation. Duncan's sons, Malcolm and Donalbain, decide to flee Scotland, fearing they will be next.
The beats worth remembering.
Macduff Discovers the Body
Macduff goes to wake the king and comes back in shock. His discovery sets off the chaos of the scene and introduces him as a character who will matter enormously later in the play.
Macbeth Kills the Guards and Has to Explain It
Macbeth says he killed the guards out of grief and rage. It is a weak explanation, and Macduff immediately asks why. Lady Macbeth's faint cuts off the questioning, which may be deliberate on her part.
Malcolm and Donalbain Flee
Duncan's sons decide separately to leave Scotland. Their flight makes them look guilty to others, which works in Macbeth's favor. Malcolm goes to England, Donalbain to Ireland.
The moments you can actually use later.
Macbeth's Justification for Killing the Guards
Macbeth claims he acted out of uncontrollable grief when he saw the guards next to Duncan's body. The explanation is thin, and Macduff's immediate question about it shows that not everyone accepts it.
Malcolm and Donalbain's Decision to Flee
The two princes decide independently that staying in Scotland puts them in danger. Their flight is rational given the circumstances, but it makes them appear guilty to the Scottish court and benefits Macbeth directly.
What to carry forward.
Macbeth's Story About the Guards Is Already Shaky
Killing the only witnesses was convenient, and Macduff notices. Students should flag this moment as the first crack in Macbeth's public performance, and as the start of Macduff's suspicion.
Malcolm and Donalbain's Flight Sets Up the Rest of the Play
Their departure removes the obvious heirs from Scotland and clears the path for Macbeth to take the throne. It also sets up Malcolm's return later as the force that will eventually unseat Macbeth.
