The problem is, she does not want to marry him and later falls in love with Romeo. Romeo is a Montague and Paris will not let them alone.

The key purpose for character development in this scene shows us what type of characters the Nurse, Lady Capulet and Juliet are and what personalities they portray. This is all important because it foreshadows what each character might do or say, and whether they are kind and caring, or cruel and inconsiderate. The scene also shows us how Lady Capulet is sort of inconsiderate and uncaring about Juliet and her life, while the Nurse knows much and loves Juliet like she herself is Juliet's mother. It demonstrates how Lady Capulet does not know much about her own daughter.
