Nightmare gave Cross permission to get out of the battlefield to get you away from it. You sneaked into the battle to watch your father fight, but one misdirected shot caused you to get hurt.

Cross was now running away with you in his arms.

WHAT WERE YOU THINKING?! DO YOU REALIZE HOW BAD YOU COULD HAVE GOTTEN HURT!?! YOU COULD HAVE DIED!! YOU CAN'T DO STUPID THINGS LIKE THAT!! YOU'RE MY RESPONSIBILITY AND I CAN'T HAVE YOU DIE!! I CAN'T LET THE ONLY THING I CARE ABOUT DIE!!!
