It was during the Capulet's ball that Romeo and Juliet had first saw each other. Once this happened, there was no force that could have stopped them from falling in love. The encounter with the servant in the city set off an unlikely chain of events. .
Shakespeare sets us up in Act I for the fateful tragedy that unfolds when they first see each other and realize who they are. Romeo finds out who she is, "Is she a Capulet? O dear account! My life is my foe's debt."" (Act I, Scene 5, Line 131-132). Juliet asks her nurse, "Go ask his name. "If he be married, my grave is like to be my wedding bed."" (Act I, Scene 5, Line 150-151).
Given the information following, none of these events could have been altered or avoided. Tybalt Capulet, a nephew and cousin to Juliet was offended that Romeo attended the party. He carries the family feud into duel challenge. Romeo trys to intervene during the duel between Mercuitio and Tybalt. When he does, Tybalt strikes Mercuitio and he dies. Romeo feels he needs to avenge Merecuitio and kills Tybalt. "And for that offense immediately we do exile him hence," (Romeo and Juliet, III, II, 191-192). Romeo's banishment and the fate involved with it is a prime factor in the deaths of Romeo and Juliet. Why banishment? In Act I, Scene I the Prince's words were quite the contrary. Was it intentional that a man of such high standard would go back on his word? Perhaps. .
Romeo's exile poisons all possibility of happiness for him and Juliet and continues them onto their tragic fate. His exile causes Juliet great sorrow, greater then if he had been executed, as stated by Juliet in Act III, Scene II, lines 133-137 "Romeo is banished- "to speak that word is father, mother, Tybalt, Romeo, Juliet, all slain, all dead. "Romeo is banished- "there is no end, no limit, measure, bound, in that word's death; no words can that woe sound."" Juliet's sorrow drives her to obtain a "knockout potion" from Friar Laurence.
