Chat Noir landed on the roof of the school without a sound, eyes darting around the perimeter to verify that no one was present at this hour. Upon seeing that the coast was clear, he slinked towards the door that led inside the building.

He tried the doorknob. Locked, as expected. He detransformed, and without a word, Plagg phased through the door. It clicked, then Adrien slipped inside.

Heart thumping, he shifted his backpack and continued down the rooftop stairwell until he reached a hallway. It was empty, although that didn't do much for his nerves. Getting caught on campus before the school opened would mean getting asked questions he would rather not have to answer.

Adrien wasn't a rule-breaker. He was courteous, mild-mannered, and above all, obedient. He did things by the book. Or, at least... he did as Adrien. Chat Noir was another story altogether.

Trying to shake off his jitters, Adrien took a deep breath and tried to summon the playful part of him that enjoyed these more mischievous types of activities.

There wasn't much for him to do for the next couple of hours but to wait until people slowly trickled into the school. He decided to occupy himself by organizing his locker, so he stepped out into the common area from the dark hallway and carefully crept to the locker rooms downstairs.

As it turned out, it was a good thing he checked it before anyone was around, for the loud gasp he let out as he discovered its contents would have surely attracted the attention of the entire room.

Inside the locker was a duffel bag full of belongings– his belongings: his passport and birth certificate, his wallet, some clothes, his favorite blue scarf, a photograph of his mother; school supplies and stationary, a brand new laptop, and an indistinct burner phone.

There was no written note, no card, no name left behind. The only identifier provided was a picture of an black and red butterfly on it.

A butterfly? Surely this couldn't be a gift from Gabriel Agreste. He'd never be this thoughtful, not in a million years.

He studied the picture, flipping it over for more clues, and found some small text on the back.

"Scarlet Peacock Butterfly", the caption said. "A vivid red and black butterfly that ostensibly poses as another toxic species in order to deceive predators."

Adrien gasped.

A fake.

Could it be...?

Adrien's fingers trembled as he picked up the phone. It was an older model flip phone. He opened it.

It had a single phone number saved in its contacts.

He selected the number, fingertip hovering over the "call" button. With a shaky breath, he pressed it. And waited.

A few agonizingly long seconds passed. Then the ringing stopped; someone had picked up.

Adrien's breath hitched and he gulped. He couldn't help the crack in his voice as he whispered hesitantly into the phone.

"...Nathalie?"
