"That hath made them drunk has made me BOLD. He is about it. That death and nature do contend about them whether they live or die."
"Th' attempt and not the deed Confound us. Hark!--I laid their daggers ready; he could not miss them. Had he not resembled my father as he slept, I had done't."
"I heard the owl scream and the crickets cry. Did not you speak?"
"I have done the deed. Didst thou not hear a noise?"
"Go get some water and wash this filthy witness from your hand. Why did you bring these daggers from the place?"
Lady Macbeth got the guards drunk and then she had some too but not a lot and in her perspective it made her "Bold." She was thinking if Macbeth had killed Duncan already and that she doesn't care if the guards die or not because it's not her problem. It also shows if it was hard to tell if the guards were dead or asleep.
"I'll go no more I am afraid to think what I have done. Look on 't again I dare not."
Among the quote "I laid their daggers ready," it shows that everything was according to plan, she gave Macbeth the daggers for him to kill Duncan and frame the guards and another quote of her saying "Had he not resembled my father as he slept, I had done't," it shows that Lady Macbeth could've killed King Duncan in a heartbeat if King Duncan hadn't resembled her father.
"Will all great Neptune wash this blood clean from my hand? No, this my hand will rather the multitdinous sea incarnadine, making the green one red.
Macbeth returns to Lady Macbeth with the bloody daggers instead of putting them on the guards hands when they were asleep. He is also paranoid that he heard someone when he was hallucinating the fact that he thought he heard someone and all Lady Macbeth heard was crickets and owls in the night sky and ground.
Lady Macbeth: "Get on your nightgown, lets occasion call us and show us to be watchers."
Lady Macbeth tells him to move on and wash the blood off his hands(which was to pretty much wash away the guilt he had). Lady Macbeth then realizes that Macbeth still had the daggers in his hands and told him to put them on the guards and smear blood on them for "framing" them that they murdered King Duncan but Macbeth refuses to go back there again so Lady Macbeth takes the daggers and does it herself.
Macbeth feels so guilty that even though his hands are clean, he feels so much guilt that he can still see the blood on his hands.
Lady Macbeth tells Macbeth to put on pajamas and pretend to act "innocent" like observers.
