(You are fighting over your "love" of Lavinia with your brother Chiron.)

"Not I, till I have sheathedMy rapier in his bosom, and withalThrust these reproachful speeches down his throat,That he hath breathed in my dishonor here!"

(You are stopping your mother from killing Lavina, you haven't had your vile way with her yet.  Where is the fun in that?)

"Stay Madam here is more belongs to her,First thrash the corn, then after burn the straw.This minion stood upon her chastity,Upon her Nuptial vow, her loyalty.And with that painted hope, braves your mightiness,and shall she carry this unto her grave?"

(I need death sounds, you are gagged, bound, and having your throat cut by Lavinia)
