One of the most important element is fate. Right from the Prologue, before the action of the play, one is exposded to the idea of fate. The Prologue explains the plot and ending of the story in that the two lovers will die because they are "star-cross'd", and it is their fate to die. No one can overcome fate, or so did the Elizabethans believe.

It is at this party that Romeo will instantly fall in love with Juliet and forget about Rosaline. The love between Romeo and Juliet will become increasingly passionate, such passionnate that it will lead to a tradegy. Therefore, fate plays an important role to the outcome of the tragedy.

Romeo observes: "Here's much to do with hate, but more with love." and Juliet notes: "My only love sprung from my only hate!" Because of the feud, Romeo and Juliet have to hide their love and get married secretly. One night Juliet will have to make a difficult desicion: either marry Count Paris and betray her true love, Romeo, or not get married with Paris and be disherited by her father.
