Romeo and Juliet is a play based on love, fate, change and tragedy. It tracks the story of two lovers from opposing families' ancient feud, in death. Like most stories, the major characters play an important role, such as the decisions in which they take. Yet the minor characters also have a good deal of influence over the ultimate destinies of Romeo and Juliet.
The first minor character to be mentioned should be Tybalt. He was a butter enemy of Romeo, and had he not been 'slain', Romeo would never had been banished. In Act 3, Scene 1, Tybalt kills Mercutio when Romeo attempts to come between the combatants and averts the fight. Out of blind rage, Romeo kills Tybalt. "And in my tmeper soften'd valours see!" Had Romeo not decided to exact revenge on Tybalt, perhaps the Capulets might have accepted him as a son. This would mean that Romeo and Juliet would not have had to hide their love for each other. Tybalt, indeed, had a large effect on the lives of Romeo and Juliet, by killing Mercutio.
Another minor character thought to have shaped the destinies of Romeo and Juliet is Paris. In Act 3, Scene 5, Lady Capulet announces that Juliet is to marry Paris. "The County Paris, at Saint Peter's church, Shall happily make thee there a joyful bride." Juliet obviously refuses and goes to Friar Laurence for help. Friar Laurence devises a plan, which will prevent the marriage and reunite Romeo with Juliet. However, this plan goes horribly wrong, perhaps causing the deaths of Romeo and Juliet. If Paris had not wished to be with Juliet, none of the following would have occurred.
Friar Laurence gives a letter to Friar John to send to Romeo about Juliet's plans. But Friar John was unable to find Romeo. "Nor get a messenger to bring it thee, So fearful were they of infection". This is another example of a minor character playing an important role.
