Lady Macbeth is one of the most powerful female characters in literature. The fact that we meet her alone on stage means that we are privy to her innermost thoughts, which are filled with the imagery of death and destruction. And when she speaks, in her next soliloquy, of her "fell purpose," her intentions are described in the most grotesque and frightening terms. First she bids the spirits to literally deprive her of her femininity, to thicken her blood, and to stop her ability to weep. Next, she prays that those same evil spirits should suckle her, converting what should be her nourishing mother's milk to "gall" (bitterness). Lastly, she calls upon the night itself to hide her actions in a "blanket" of darkness. It is no coincidence that these last words reflect those of Macbeth in the previous scene: Shakespeare is creating a strong verbal bond between husband and wife that will continue throughout the play.
When Macbeth enters his castle, his wife greets him in a way that again recalls the words of the Witches; in particular the words "all-hail" and "hereafter" chill the audience, for they are the exact words spoken to Macbeth by the Witches. The dialogue that follows their initial encounter is fast, urgent, and disturbing. Shakespeare uses half-line breaks to intensify the drama of the moment, each "partner in crime" picking up the rhythm of the other's speech:
M: My dearest love,Duncan comes here tonight.
LM: And when goes hence?
M: Tomorrow, as he purposes.
LM: Oh, never Shall sun that morrow see!
Shakespeare uses the same technique immediately after the murder.
