Noir gone Blanc (UNDER REVISION)

THIS STORY IS UNDER REVISION. PLEASE EXCUSE THE CHANGES IN WRITING STYLES. I made this when I was like 14, and I'm 18 now, so I'm fixing it.

I ran as he chased me, his white claws just brushing the tips of my bluebell hair as he tried to grab at me. There was a loud hiss behind me as he missed again.
"M'lady," he growled from behind me. I stumbled up to a cataclysmed building, and tried the door, panicking slightly to find that it was stuck. I tugged harder at it, as Chat Blanc slowed to a walk, his bright blue eyes boring into the back of my head.
"M'lady," he repeated as strolled up to me. I quickly turned around and tried to duck to the side, with no luck. He slammed his hand into the wall, next to my head, caging me in. "You can't hide from me. We are meant to be together." He grabbed my chin, and tipped it up, so I was looking right at him. The white cat smiled, not a trace of sanity left in those orbs.

Marinette would definitely be haunted by the memories of Chat Blanc, so in this story, what were to happen if he plagued her nightmares? What would happen if he made a return, but in a different, more twisted version? (Marichat/Mariblanc)
