-Miraculous Ladybug and Chat Noir-

"WHAT THE HELL IS WRONG WITH YOU!"

The yell seemed to reverberate all throughout the streets of Paris. The ground seemed to shake with the force of it and all the spotted being did in response was remain still, head held high. "What I had too."

"You know aswell as I do what fate you've sealed Marinette to! You know what that will do to her, if it hasn't already!" Plagg loomed over the spotted Kwami, as the embodiment of destruction that he was. Her indifference only worked to fuel his rage, present in his flaming green eyes that poured into hers.

"Of course I do, Plagg, but this was the only course of action!" Tikki didn't waver in the slightest.

"Only course of action my ass! You know the mental abuse that splitting a person's soul has on the recipient! And you know that all that does is fill them with hate and rage!"

Tikki bristled. Couldn't he understand the severity of a Paris without Ladybug? A force of evil such as Hawkmoth can only be prevented by a pure and good power such as hers. Whenever a Ladybug had hung up her spots the world had fallen into disarray. Well never again. Tikki rose to hover above Plagg, her cool eyes now boring into his. The rage contained there flickered under the weight of her stare but did not weaken.

"I made the right choice, Plagg. Now either you accept what I did or you don't, I don't care either way, but I will not take back what I did. It's already too late, and even if it wasn't I wouldn't but Marinette and Ladybug back together. It's the life of one girl for all of Paris."

"That one life is your holder!" Malice rolled off him in waves. "Your Guardian! If you won't fix it, I will. I'll tell Chat Noir and I'll put Marinette back together myself!"

Tikki rushed forward at Plagg with her bright light, wrapping around him. "You will do no such thing! You'd be making a mistake, she is already to far gone!"

Plagg's fiery rage cooled to a cold hard stare. His power coiled inside him and he released the tiniest pulse against the bindings, crumbling them to ash. "Don't forget who I am Tikki! Just like you I am a core kwami, the wielder of untamed destruction. You cannot restrain me as much as I cannot restrain you, but if it comes down to this I will fight to save Marinette."

Absolute calm stretched across Tikki's features, forcing a wave of discomfort through him. "You won't, I know that. Because, as you said you are the wielder of untamed destruction. Your power could easily combat and even overwhelm mine, but the resulting damage? Inconceivable. But my power... I can focus it, use it to stop you at every turn. We are divided on this Plagg, and as such it falls to me to make sure what needs to be done is done. So I leave you with this threat, you care for Marinette so much, well, if you so much as hint of what has occurred to your holder I will erase Marinette completely by breaking her and then I'll follow up with your holder. Do you understand?"

Plagg's cool rage erupted once again, fueling his power, forcing it to show from a dark aura that surrounded him. One thought and she'd be gone. He didn't want to but what she'd turned into couldn't be allowed to remain. And yet, he was helpless. Tikki was right, he couldn't lash out, his power would kill millions. He yelled out again with frustration and turned away from Tikki. "You've made a grave mistake Tikki. One day you'll see that and it'll be too late."

Silence held between the two, neither bothering to break it as all that needed to be said had been. Plagg sighed, before flying away. "Goodbye, Tikki."

TIkki stayed there, eyes following the black streak moving away from her. She let her head fall, before whispering "Goodbye, Plagg."

-End Chapter 18-

It's short, sorry, but I didn't want to put anything else in this chapter, so that it doesn't take away from the impact. Also sorry I've been away for so long, I swear it may start being a cliché for miraculous fanfic writers to have lots going on in their lives because I swear it's nearly all of us XD. Anyway a quick rundown of corrections I want to make and also some info, First I'm going to be rewriting some earlier chapters as I believe they are horrible, two, I want to make sure people realize that Tikki isn't acting as ladybug, it's the embodiment of Marinette when she becomes Ladybug (confident, kind etc), Ladybug is still a good person who is ignorant of what Tikki has done. Third and final, this doesn't follow canon past season 3 and Adrien is not in a relationship with Kagami. Hope to see you soon.
