Luki's eyes had never quite shown this much of a mixture between confusion and absolute rage. You had to be borderline suicidal to attempt to jump on a twin and hold her down (especially when she was in such an uncontrollable state) and yet, Cloud took a hold of her and threw her body to the floor with him, pining her down.
She was fighting, struggling, shaking her head, moving her legs, trying to lift up the armed arm and take another fatal swing at the man above her. She would close her eyes while screaming, panting afterwards, then locking her maddened glare on light blue eyes trying to reach her.
Luki could hear Cloud's words - perhaps even understand them to a certain level - but the hound in her was too infuriated and too irrational to listen to his reasoning. She just kept fighting and struggling, grunting, snarling, screaming. This went on for a few good minutes, Cloud's appeals lost somewhere in the middle, up until the second Luki finally stopped, breathing heavily, bangs covering her sweaty and dirty face, head resting against the floor.
And then came that moment. The moment where Cloud's force on her faltered just a little bit - he must have thought it was safe, now - but enough for Luki to seize the opportunity and break her arm free and thrust it, one of the blades stabbing the man through his scapula. It would have hit a vital point, but Luki's clouded thoughts and lack of time for a better reaction limited her precision.
And yet, despite finally injuring Cloud, something she had been so bent on doing from the very beginning, part of the bestiality originally present in her eyes was gone. She looked almost... surprised, to know that one of her blades was finally sticking out of the blond's body with his blood on it - she could smell it, and the animal in her mind almost craved to taste it as the proof she needed to carve her victory in stone - and her mismatched eyes could do nothing but stare, parted lips, panting softly through them.
