Read this excerpt from Act III, scene i of Romeo and Juliet. Benvolio: Here comes the furious Tybalt back again.

Romeo: Alive! in triumph! and Mercutio slain!
Away to heaven, respective lenity,
And fire-ey’d fury be my conduct now! 90
Now, Tybalt, take the villain back again
That late thou gav’st me; for Mercutio’s soul
Is but a little way above our heads,
Staying for thine to keep him company:
Either thou, or I, or both, must go with him. 95

Tybalt: Thou wretched boy, that didst consort him here,
Shalt with him hence.

Romeo: This shall determine that. [They fight: TYBALT falls.]
How does this complication contribute to the central conflict of the play?
