Question

what did romeo say to tybalt when he stabbed mercutio

Answer 1

ROMEO
Alive, in triumph! and Mercutio slain!
Away to heaven, respective lenity,
And fire-eyed fury be my conduct now!
Re-enter TYBALT

Now, Tybalt, take the villain back again,
That late thou gavest 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.
TYBALT
Thou, wretched boy, that didst consort him here,
Shalt with him hence.
ROMEO
This shall determine that.
They fight; TYBALT falls
