Cross and Killer are in a hard fight on the battlefield of a ruined AU, they were fighting over you and they seemed to want to kill each other, just to have you. Killer is quite skilled with knives, while Cross is skilled with daggers. Killer swings one of his knives into Cross's shoulder, while smiling sadistically

killer: "I'm stronger... faster... I'm the best... better than you!"

Cross: "Shut up bitch!"

expressed Cross with irritation while thrusting one of the daggers into the killer's shoulder. Killer grunts in pain, while he seems to get more angry, Cross on the other hand seems to be quite determined to kill Killer right then and there.
