Chapter Text
The moon hung low over Paris, its pale light slipping through the thin curtains of Marinette’s bedroom and spilling across the quiet room in a wash of cold silver. It painted long shadows across the walls, stretching over the scattered sketches pinned above her desk and the half finished designs that lay abandoned beside her. Normally, the sight of her sketchbook would fill her mind with inspiration. Tonight, it sat open and forgotten, the pencil lying motionless across the page like even it had lost the will to move.
Marinette sat perfectly still at her desk, her chin resting in the cradle of her hands, elbows planted firmly against the wood as though the weight of her thoughts might otherwise drag her to the floor. Her eyes were unfocused, staring somewhere beyond the walls of her room, beyond the quiet streets of Paris, beyond everything she had once believed was simple and safe.
Her thoughts circled one name, again and again, like a storm that refused to pass.
Felix.
Argos.
Her heartbeat thudded loudly in her chest, heavy and uneven, as the memories she had tried so desperately to push away clawed their way back into her mind with merciless clarity.
The Diamond Dance.
The ballroom glittering with chandeliers and laughter that had seemed so harmless only moments before everything changed.
Marinette’s fingers slowly curled into fists against the desk, the knuckles paling as she remembered the moment the air in the room had shifted when Felix had stepped forward with that same detached calm he always wore, as though the entire world was nothing more than a game he had already mastered.
Red Moon.
Even the name sent a chill down her spine.
The sentimonster had loomed over the ballroom like a nightmare pulled straight from the darkest corners of imagination, its crimson glow staining everything it touched with an eerie, suffocating light. People had screamed. Some had tried to run. Others had simply frozen, unable to comprehend what they were seeing.
But Argos had stood perfectly still beneath it all, his posture relaxed, his expression composed, as though the chaos unfolding around him was nothing more than an elaborate performance meant solely for his amusement.
Marinette squeezed her eyes shut for a moment, but the memory refused to fade.
The snap of his fingers.
The terrible, effortless finality of it.
One moment the ballroom had been filled with terrified voices and desperate movement, then the next, it had been silent.
People had simply vanished.
Erased as easily as dust brushed from a table.
A shaky breath escaped her lips.
“I can’t believe this...” she murmured into the quiet room, her voice barely louder than the whisper of the curtains stirring in the night breeze. “He... he could’ve killed everyone.”
The words felt heavy in her mouth, as though speaking them aloud somehow made them more real.
Because that was the truth she could no longer deny.
Argos wasn’t just dangerous.
He wanted to be.
There had been something in the way he carried himself that night, something far colder than the casual arrogance he normally wore like armor. It wasn’t the smug confidence of someone who simply believed they were better than everyone else.
No.
It had been something deeper.
Something darker.
The quiet certainty of someone who believed the world itself existed only to be shaped by his will.
And with the Peacock Miraculous in his hands, that terrifying belief wasn’t just empty pride anymore.
It was power.
Unimaginable, terrifying power.
How had she never seen it before?
How had she looked at Felix so many times, heard his biting sarcasm, watched the way he kept everyone at arm’s length, and never realized just how deep the darkness beneath it all truly went?
Had she really been that naïve?
Marinette pressed her palms against her temples, as if she could somehow quiet the relentless storm of thoughts inside her head.
Because the truth staring her in the face now was far worse than anything she had imagined.
Felix Graham de Vanily wasn’t just a spoiled heir with too much money and too little empathy.
He was a threat.
Argos was an enemy.
An enemy who could erase people from existence with nothing more than a gesture.
And if no one stopped him...
He could destroy everything.
Her breathing grew uneven as the weight of that realization settled deeper into her chest, thick and suffocating like a storm cloud pressing down over the city.
“Why...?” she whispered into the empty room, her voice trembling slightly despite her efforts to steady it. “Why did he do it...?”
The question lingered in the air, unanswered.
“Why does he hate Ladybug so much...?”
She hadn’t even had the chance to confront him properly.
Every encounter they’d had in the past had always felt strange in ways she hadn’t been able to explain, like trying to grasp something just out of reach. Felix had always been distant, guarded, his emotions hidden behind layers of dry wit and cutting remarks that made it nearly impossible to tell what he was really thinking.
But this...
This was something else entirely.
This wasn’t just coldness.
This was something far more dangerous.
And yet...
Even now, with the memory of Red Moon burning behind her eyes and the echo of that terrible snap still ringing in her ears...
A small, stubborn part of her refused to give up completely.
Because somewhere beneath all that cruelty, beneath the arrogance and manipulation and quiet menace...
Felix was still human.
Wasn’t he?
Marinette pushed herself abruptly out of her chair, the sudden movement sending it scraping softly against the wooden floor. She began pacing the length of her room, her bare feet whispering against the floorboards as restless energy surged through her.
The uncertainty gnawed at her relentlessly.
Felix was unpredictable.
Dangerous.
A force of nature wrapped in a perfectly composed smile.
But at the same time...
There had always been something else there, something buried so deeply it was almost impossible to see.
Pain.
Loneliness.
A wound that had never truly healed.
And despite everything that had happened...
Despite the fear clawing at her chest...
She couldn’t help but wonder if somewhere inside him, there was still something worth saving.
Marinette stopped pacing and stared out the window at the sleeping city below, the rooftops of Paris bathed in moonlight.
Her reflection stared back at her in the glass, tired eyes, clenched jaw, determination slowly replacing the fear that had threatened to swallow her whole.
Because no matter how complicated things were...
One truth remained.
She was Ladybug.
And Ladybug had sworn to protect Paris.
Even if the enemy she had to face this time was someone far more dangerous than any villain she had fought before.
Even if that enemy was Felix.
Even if part of her was still afraid of what would happen when they finally stood face to face again.
Her hands slowly curled into fists at her sides.
No matter what darkness waited ahead...
She would face it.
No matter what it took.
