Previously in episode Chat Blanc:

"Okay, okay!" Ladybug reached out a hand, her heart pounding as the horizon from all points turned the dangerous white of her akumatized partner's Mega Cataclysm. "I'll give you my miraculous Cat Noir!" She had to stall, she had to find the solution. She had already called on her lucky charm, but still she had no leads to end this.

Her capitulation created an immediate reaction, the powerful attack dwindling as fast as it had come into existence. She couldn't help but tense as the ice blue eyes pined her down once again, briefly. "I'm not Cat Noir anymore. I'm Cat Blanc." He flicked his bell with the same hand that had just been about to destroy the universe. Marinette zoned in on the small sphere; the last item on Cat that could be akumatized.

You can do this, just get close enough to take it… Her former partner watched her every move, taking in her slumped shoulders and downtrodden look as she approached. Placing her hands against his chest, she looked up into eyes she desperately wanted to see green again. He must be able to hear me, he must know I'm trying to help him deep down… "You will always be Cat Noir to me." And it was true; this akuma wasn't her partner, it was the manifestation of something terrible, something she didn't understand.

Something she had to fix.

Ladybug leaned in, knowing she was playing a bit dirty against the feelings Cat had always held for her. But she had to save him; just keep him focused, eyes looking into hers-

Her hands, which had been creeping so carefully towards their goal, were snatched by two clawed gloves.

Gasping, she tried to reel away, but was held tight. "Cat." Her voice came out slightly panicked, taking in the manic glint to his eyes. No! This wasn't supposed to happen!

"You seem to have forgotten bugaboo, but-" He leaned in, encroaching her space in a way he never would have dared before. "I. know. You." Wrestling both wrists into one hand, he reached forward harshly, jerking out one earring from her left ear.

"No!" She twisted as the sparks of power started to dance around her form. The eraser, her shot for figuring out this mess, dispersed in a glitter of magic. Dropping down, she almost loosened his grip, gambling the risk of it being better for them to tumble back into the overrun Seine then what he was about to do. Instead, he controlled their landing back onto the base of the Eiffel Tower, pinning her beneath him despite her best efforts to wrestle him off. Chills ran straight to her heart as he laughed off her attempt.

"Don't struggle, M'lady. What happened to trusting your partner?"

Managing to rip one hand free, she covered her one remaining earring with a half-gloved hand. Curling so the one remaining piece of miraculous was beneath her, she closed her eyes tight, praying Alix would come back in time to stop him. "This is the akuma talking! You have to stop!"

She felt the points of his glove dig into her skin, prying her hand off enough to reach for her earring. "My Ladybug, always playing hard to get. This is the only way to save us!" She cried out from more than pain as her ear tore from him ripping out her remaining miraculous. Instantly, what little power she had left disappeared, revealing her regular form to the akuma. Without her powers, Marinette couldn't even push him off as the miraculous adjusted to it's knew owner, the back ends becoming subtle clip ons.

He stood up, backing away from her as the powers of creativity and destruction began to swirl around his form.

"No!" This wasn't supposed to happen! She was supposed to be a hero! She was supposed to save her partner! "Cat, please!" She stumbled up; her right hand bloody from clutching at her torn ear. The fight had drained her more than she realized, and without her miraculous to enhance her endurance, she staggered too close to the edge, her foot slipping on the rusted iron. Falling off the side, she realized something that made her truly afraid.

Without the protection of her miraculous, she would die.

But almost immediately, the same hands that had just attacked her entrapped, holding her close as they fell together. Deftly, Cat Blanc adjusted like the cat he was, using the momentum to leap along the tower, towards the center where there was still some semblance of a toppled platform.

Marinette could do nothing but cling to him, frustrated with herself for being so paralyzed. Red and black energy zinged passed her hurt ear, playing along her form as Cat held her close.

"It's going to be okay, Marinette. I won't lose you again."

Finally, he settled on a platform, letting her down with surprising gentleness. If she kept her eyes closed, she could almost pretend it was Cat Noir. But it isn't. And you won't ever see him again if you don't do something!

Before she could move away- to face him, attack him, run, she wasn't sure- his hands grasped her shoulders, keeping her in place and only able to crane her head back to see an almost pensive expression.

"Why… why save me, you have what you wanted." She didn't like how her voice cracked, how hard it was to hold herself up in exhaustion. Alix, where are you? What happened?

"This Cat is nothing without his Lady. You know that, bugaboo." She startled when one hand left her shoulder to gently pull at the strands of her hair. "You're wearing pig-tails again. I haven't seen your hair up in pig-tails since…" He trailed off, lost in some thought.

He wasn't making any sense; she always wore her hair in pig-tails. The energy drew close to their forms, encompassing them in an almost protective cocoon. Tikki? Does she have any control over what's happening? What about little Plagg? Likely sensing that she was going to try again, the white arms trapped her in their embrace again, keeping her arms to her sides. Keeping her from being able to do anything but watch. "Let me go, Cat. This isn't right." She trembled slightly, knowing her words could insight the anger she had seen earlier, but she needed to try.

At her words, he held tighter. Marinette flinched, but it was only a hold to keep her more closely caged, nothing about it aggressive. "I'm sorry, Marinette. But I can't. Cat Blanc made that mistake before. I won't do it again."

"Cat." She pleaded again, ignoring the feeling of her blood running hot and unchecked down the side of her neck. "I need to fix this. You can't use the miraculous together- there's a price to whoever calls upon them for a wish!"

"No price will be worse than this." Still he held her, his head falling next to hers, taunting her with how close her chance to fix this was. The energy coming from the miraculous swirled faster, growing brighter as the wish in Cat Blanc's mind grew assuredly. "I told you, Princess. I'll fix everything. We'll be in love again, just how it should have been, forever."

"This won't make me love you!" She blurted, surprised when she teared up at the truth in those words.

This time, his grip did become worryingly tight. "You're right, I can't make you love me." The lights swirled quickly now, expanding out into the far stretches of the world, drowning everything in its power as Cat Blanc's wish came to fruition.

"But I can make you mine."

It's haitus season. And while I was hoping someone else would take on the 'what if' AU of Chat Blanc, I haven't seen it.

And I NEED it.

So Here's my contribution. A bit dark, but only a touch. It's a fine balance with these lovelies. I think I'll add a few more pieces to it, the aftereffects of Chat Blanc's success, the revelation for Marinette on what DID happen. But, I don't know how it can end in a happy ending for our favorite couple
