Act Two Scene 3 Lady Macbeth takes center stage twice in this scene. What do her actions reveal about her character?

In Macbeth, Act II, Scene iii, Lady
Macbeth opens the scene. Shortly afterward, Macbeth enters. The conversation between
them is about the fact that Macbeth has just recently murdered Duncan and he feels
something has changed within him. Macbeth admits that because of the murder he will no
longer be able to sleep:

Macbeth shall sleep no
more!

Macbeth swears that he
heard this pass from the lips of Duncan's guards. Lady Macbeth, angered at the fact that
Macbeth seems to becoming weak, "You do unbend your noble strength," decides that she
must do something to insure the finger is pointed at someone other than Macbeth. Lady
Macbeth exists so as to insure that McDuff and Lennox do not blame
Macbeth.

When Lady Macbeth reenters, she tells Macbeth that
she has returned the daggers to the sides of the guards and smeared them with Duncan's
blood (basically framing them for the murder of Duncan). Lady Macbeth tells Macbeth that
she is now just as guilty as him, but she "wears a heart of white." Lady Macbeth states
that a little water alone is able to clear them of their
deed.

What the scene tells readers about Lady Macbeth is
that she sees her husband as weak and acknowledges the fact that she must take charge to
insure that Macbeth gains the crown as stated by the witches' prophecy. Lady Macbeth,
here, seems to be the far stronger character while, at the same time, her brutal
character is uncovered.
