Blood
The glass test tube in front of him split, his fingers curled as he's pressed further against it as the blade he had been stabbed with dripped with blood. His blood. He grimaced, gritting his teeth and retaining to slipping calm as he spoke quietly. He couldn't turn to face his attacker. "Who are…" He stopped himself immediately, seeing the attacker's likeness reflecting off Jenova's prison and that familiar scent that came with the realization.
He had been stabbed in the back by her.
"Claire…" He spat her name bitterly as though that name doesn't mean anything to him any longer. His face contorted with silent rage that she couldn't see. "How dare you interrupt—!"
"Shut up!" Lightning barked, silencing the man and surprising herself with how much authority and hatred it carried. How dare he still use her name! "Just shut up!" She plunged the broad sword's blade with more force. She half-expected herself to be trembling on how rashly she acted on this, she didn't even need to see her reflection or his face. She stood firm on her wrath; hate etched on her features, no regrets registered to her mind.
Time seemed to stand still and she was frozen stiff in place. He stabbed her and she stabbed him, his blood flowed freely on her hands as she released her former lover and watched him crumple to the ground, hands slid off the glass desperately as to claw for support.
