In this scene the others find out that Duncan is dead. This makes Macbeth worried because they start to suspect people but also Malcom and Donaldbain are scared because they might be next. A quote to prove this is ” there are daggers in men’s smiles,” which means they might be smiling but then will kill you when you least expect it. To prove Macbeth’s worriedness and lady Macbeth’s assistance is that she fainted to take the tension of Macbeth’s shoulders.
