Which line in this excerpt from act IV of Shakespeare's Romeo and Juliet best reveals the dramatic irony of the scene?

NURSE: Mistress! what, mistress! Juliet! fast, I warrant her, she:

Why, lamb! why, lady! fie, you slug-a-bed!

Why, love, I say! madam! sweet-heart! why, bride!

What, not a word? you take your pennyworths now;

Sleep for a week; for the next night, I warrant,

The County Paris hath set up his rest,

That you shall rest but little. God forgive me,

Marry, and amen, how sound is she asleep!

I must needs wake her. Madam, madam, madam!

Ay, let the county take you in your bed;

He'll fright you up, i' faith. Will it not be?


(Undraws the curtains)


What, dress'd! and in your clothes! and down again!

I must needs wake you; Lady! lady! lady!

Alas, alas! Help, help! my lady's dead!

O, well-a-day, that ever I was born!

Some aqua vitae, ho! My lord! my lady!
