This had originally been a oneshot, but there was a surprising number of follows and calls for continuation. To be honest, I wasn't quite sure where to go, but this popped up in my head randomly. Basically Marinette freaking out and discovering some things that should've stayed secret.

Nino–

–was Tortuga.

Chat Noir–

–somehow knew Lady M. Which meant he knew Marinette, who was also Ladybug.

Marinette–

–'s brain really hurt.

She didn't know if she could go to school the next day.

But in the end, she decided to suck it up and deal with–well everything.

That didn't mean she wasn't scared about seeing her friends again. Actually, she was more pissed off than anything.

She had no idea what to do with the situation anymore. It had quickly spiraled out of control, like a story whose author needed to accelerate the plot without knowing which direction to go in.

But, she was Ladybug. Even if her friends didn't know, even if she herself forgot sometimes, she was Ladybug, protector of Paris, and as of last night, only sane superhero in the city of Paris.

She'd be damned if she let her crazy friends and superhero partners drive her insane.

(Tikki would later attest that Marinette was already driven insane at this point)

Her thoughts and worries and confusion swirled around in her, and she didn't even realize what was wrong until she arrived at school.

Her hair.

She had forgotten to put it up.

She self consciously reached up to pat at her loose curls. She'd worn them in pigtails since she'd gotten her long tresses chopped the year before.

Marinette shook her head, and her black hair swirled around. She had to focus on the task at hand.

What task, she wasn't sure, but her emotionally riled up brain didn't pause to think about that.

She was early that particular day, which never happened, but she was a girl on a mission. She plopped herself down on the steps of the school to wait for the others.

The first one to arrive was Nino.

He was making his way up the street when Marinette caught sight of him. The tan boy was nodding his head to whatever music was coming out of his headphones, oblivious to the coming storm that was Marinette Dupain-Cheng's wrath.

He turned into the courtyard, and Marinette stalked up to him. His eyes widened comically as he saw the petite half-asian barreling towards him, and he hesitantly pulled his headphones off. Her grim appearance caused him to stutter in surprise.

"He-Hey Marinette! You're early today. Like real early. As in why the heck are you here already, you've barely ever been on time. W-wait, your hair-it's down." He sounded shocked.

Marinette didn't answer. She was glaring at him, hip cocked to the side, eyes narrowed.

Nino gulped nervously.

Tilting her head, Marinette scrutinized him. If she squinted hard enough, pretended that there was a green hood around his head instead of his ridiculous red cap, maybe–just maybe, she could see it.

She held her hands up to his face, not paying attention the confused and worried look Nino was throwing her. Holding her hands in two circles, she held her 'mask' in front of his eyes and glared.

Yup. Nino was the goddamn turtle miraculous holder.

Which really made zero sense to Marinette, because the turtle miraculous was supposed to represent wisdom and patience, not amusement at his friend's suffering.

Marinette threw her hands up in exasperation, turned around, and stalked back to where she was sitting before, still having not said a single word to Nino.

Nino followed her cautiously, and prodded at her side.

She glared even harder, and tilted her body away from him. He was Tortuga! And he never acted like it! He kept such a big secret from them, and here he was never giving a single indication that he was moonlighting as one fourth of Paris's quartet of heroes.

Her hypocritical thoughts were interrupted by the arrival of Alya.

"Dude, thank god you're here. I think Mari's broken." Nino desperately grabbed at the blogger's arm, and put her in between him and Marinette.

Alya let out a noise of amusement.

He whispered dramatically, "I think she might've been akumatised! She hasn't said a word to me, she's glaring–She never glares Alya!–and she's wearing her hair down."

Marinette glared even harder.

Stupid Turtle.

Alya waved a hand in front of her face. Marinette barely saw her.

She bared her teeth at Nino.

Nino turned tail and ran.

Unfortunately for him, Adrien had just started making his way over to them, and Nino full on collided with him.

"Nino, dude! Are you okay? I expect things like that out of Mari, but you're usually so calm. Not that Mari isn't calm, she's just a little more prone to collisions…," Adrien helped his best friend back up.

Nino hid behind him. "Mari's been akumatised. Or something–," he mumbled, but Adrien didn't hear the rest.

He dropped his bag and ran over to Marinette, nearly knocking over Nino again.

He grabbed Marinette's shoulders and shook her hard. "Marinette! You can't be akumatised, you're always so happy! Unless we're talking about the whole shipping thing, and I'm really sorry that I was so mean to you about it that was stupid of me. But please be okay–Oh, no! She's not wearing pigtails she's been akumatised hasn't she, oh god–I uh–I have to go, I'm sorry–,"

Marinette, normally who would've swooned due to the fact that Adrien was touching her, was still so out of it that she barely realized that her crush was basically coddling her.

Alya patted Adrien, "I'm sure she's not akumatised. She hasn't said anything yet. I think she's just really mad at Nino for something," Alya brightened, and her grin turned cheeky, "Maybe she finally realized that the shirt Nino bought for her is total bullshit!"

Marinette turned her glare to Alya.

Stupid.

Ship.

Ping.

"On second thought, maybe she is akumatised," Alya said nervously, and started backing away, "Girl, ya know, you're scary when ya glare."

Ships were stupid. Just let them drown for god's sake.

She would've lived in blissful ignorance of Nino's alter-ego, or the fact that Chat knew her–knew her!– if Alya hadn't started this stupid shipping thing.

The first bell rang, and she turned away from them, stalking up the stairs of the school, as she entered the building before class started for the first time in months.

The trio behind her shrugged helplessly at each other.

Alya whispered, "I guess we'll have to deal with Dark Marinette today. Dear God, I really hope she isn't akumatised, she's actually kind of scaring me."

The boys nodded, and they followed Dark Marinette into the school building.

Marinette was unaware of the caution of her friends, and made her way single-mindedly towards their classroom. As she stormed towards her seat, she nearly ran into Chloe.

"Ugh! Look at the trash today. Watch where you're going…" Chloe trailed off as Marinette turned her glare at her, and brushed past the blonde without a word. Chloe nearly peed her pants.

Alya, Nino, and Adrien filed in minutes after Marinette, and were surprised to find Marinette sitting calmly in her seat, and Chloe trembling in her own, leaning her body against Sabrina as if she was trying to get as far away from the aisle as possible.

Kim shuffled down to meet them. He whispered, "Dudes, I've never seen Marinette like this. Is she trying to develop a resting bitch face or something, because boy is she succeeding."

They could only shrug and makes their way into their respective seats.

There was still a couple minutes before class started, and everyone chattered as they pulled out their tablets and notebooks.

A thought suddenly occurred to Marinette.

She smirked evilly, and several of her classmates who witnessed the action would later claim that it had traumatized them.

She turned to Nino, who had been whispering to Alya and Adrien, and pasted on a wide smile.

The conspiring trio stopped at Marinette's sudden change.

"I was wondering if I should get a pet turtle. They're so cute." She narrowed her eyes at Nino.

He sputtered, and Adrien patted him on the back.

Alya raised an eyebrow, and held a hand up to Marinette's forehead. When she removed it, she frowned. "Okay…so you don't have a fever, but there's definitely something wrong."

Marinette's evil plan was just starting to form. "Oh, I've never felt better."

She thought of how Chat Noir had claimed to be friends with her–Lady M. But only a couple people knew she was Lady M. How odd.

She raised her voice so that it carried throughout the classroom. "I was thinking of getting a black cat, but I thought it would be too troublesome. But I guess turtles aren't completely innocent either. In fact, I would say that the whole situation was really the turtle's fault."

Her three friends looked slightly lost now. Adrien was slightly pale, and Nino's eyebrows looked like they would disappear of his forehead at any moment. Alya was just confused.

"Maybe I like bees the best, even if they do sting. Maybe that's why Queen Bug is better. She's annoying but at least she doesn't know me," Marinette mumbled the last part under her breath.

"What was that?" Nino asked, looking slightly worried.

Alya, who had always been the brightest of the group, suddenly caught on, "You-You're talking about the superheroes aren't you?"

Marinette ignored Alya's question and focused on her own.

Hmm…But who was Chat? Marinette turned her gaze towards her classmates. Only Nino, Adrien, and Alya knew her as Lady M…right?

Oh.

Oh no.

But–that–

–no it couldn't be–

Marinette let out a gasp, and nearly fell back in her chair. Alya helped steady her, but Marinette shrank away from her friend's gesture.

She knew who Chat Noir was!

It.

Could.

Only.

Be.

–ALYA.

How could she have missed it before! The obsession with Ladybug was there in both her civilian and superhero life.

Maybe the black cat miraculous drastically changed one's appearance. Marinette wasn't too concerned with that particular aspect of her theory.

Now, she only needed more evidence. She turned her gaze back to Nino. Might as well confirm two identities at once.

"AHHHHH…." All at once, the conversations in the room stopped.

"…Marinette, babe…are you okay?" Alya put her hand against Marinette's head, who only continued to wail.

"I-uh-I NEED the MIRACULOUS-yeah that's it–CHAT NOIR AND TORTUGA SHOW YOURSELF I MUST HAVE YOUR MIRACULOUS!"

Nino backed away, "Dudes, I told you Mari was akumatised. I wonder what happened…I gotta go though, I just remembered that I left my literature homework in my locker, Al, take care of her before Ladybug gets here alright?"He ran out the room.

Alya nodded and grabbed Marinette's arms, which had started flailing about. Marinette smirked internally, of course Alya would take 'care' of her, she was Chat Noir.

Adrien rushed after Nino, and minutes later, Chloe exclaimed, "Ugh–I can barely stand normal Marinette, I'm not gonna deal with weird akumatised Marinette either," and left the classroom.

But Alya wasn't leaving.

Marinette needed to confirm that Alya was Chat, but why wasn't the girl leaving?

She suddenly jumped up, and rushed on the classroom, sure that Alya would chase after and transform.

Not checking to see if her best friend was behind her, she ducked around a corner, just as she saw Chloe–

"Pollen, Stinger out!"

–Yellow sparkles.

Queen Bee?

Not the identity she was going after.

–Wait what? She–what? Alya–Chat–Chloe–Bee? Huh?

Marinette stared at the hero, who suddenly noticed her. She couldn't move. Her brain hurt.

How come two other superheroes were also in her class, like, what were the odds?

–Wait! How come Chloe go to be a hero, she was a terrible person! That wasn't fair at all!

Queen Bee ran up to Marinette, who was sliding halfway down the wall.

"Are you okay, Marinette?"

"Nghhh-bleheh…"

Another hand helped lift her up. A black, leather-clad one. "Um…Queenie? I think she's broken."

Chat.

At that exact moment, Alya came skidding around the corner, camera in hand, calling for Marinette.

She shook her head.

Alya.

Turn.

Chat.

Turn.

Alya.

So…Alya wasn't Chat?

Then…who else?

Not Nino, sneaky little turtle.

Not Alya, because well–she was right in front of her, next to Chat, and unless time travel had occurred, that was impossible.

So…

–Oh dear lord–

–Adrien.

Marinette fainted right then and there.

lol does anyone actually want me to continue? If you have any ideas, I totally would! Sorry if this wasn't what you were expecting, or if Marinette was a little too OOC for you, but hey, I felt like this was a perfectly reasonable way to react.

Thanks, FroOrange.
