In act 4 of Romeo and Juliet what is one example of dramatic irony

In scene 4, lines 1-30, Capulet tries to get Juliet to marry Paris. Capulet decorates the wedding to where it would be perfect. He wants Juliet to marry Paris because he was very wealthy and he had great fame.

Capulet had given Juliet her freedom as a child and he wanted her to hurry up and marry Paris before she got too old.

The audience, Friar and the nurse were the only people who knew about Romeo and Juliets marriage. Romeo and Juliet fell in love and they knew that they shouldnt be able to get married. This makes it a dramatic irony because Juliet is already married to Romeo.
