Had some a lot of spare time (again), so enjoy.
We start the day after the incident, at the Agreste Mansion, in Adrien's room.
Adrien is lying down in his bed, but is tossing and turning. He then hears echoes of mysterious voices.
???: You know you can't win.
???: Now! FIRE NOW!!!
???: We will see each other again...
Adrien wakes up, breathing heavily.
Adrien: Who was that? What is happening to me?
Plagg: (yawning) Can you keep it down? I was having a good dream.
Adrien: Sorry, Plagg. (getting out of bed) It's just that after last night, i've been hearing things, strange voices. I don't who they are, but they sound... familiar.
Plagg: Probably just a nightmare. You did try to help Ladybug.
Adrien: Yeah, but... what was that.
Adrien then looks at the clock.
Adrien: Uh oh, i better get ready.
Adrien spends the next 45 minutes getting ready for school. He then grabs his bag (with Plagg flying in) and heads out the door and down the stairs.
He turns, seeing Gabriel walking out of the atelier.
Gabriel: ...we need to talk.
Adiren: Sure, what is it dad?
Gabriel: After what happend last night, i think you should stay home.
Gabriel: I'm concerned about you. After the incident and what you did, i don't think it's safe for you to go nor do i think you in a condition to go.
Adrien: I'll be fine, Dad. Trust me.
Gabriel:..... Fine, but the moment something happens, i'll
Adrien: I know dad, we've been through this before. I gotta go, Bye!
Adrien walks out the door.
Gabriel: I should have never made that deal. Loup... when i find you, you'll regret summoning me.
Meanwhile, at the school, Marinette, Alya, and Nino are hanging in the courtyard, telling everyone what happend.
Marimette:... after that, the driver took us home, one-by-one.
Myléne: And you guys are alright? After that?
Alya: No, we were all still shaken. We didn't talk on the ride home, not even a whisper.
Max: What about Adrien? You said he was staring into that orb.
Nino: Yeah, he wasn't even knocked back. The dude was just staring into it. But, after his dad got him... well.
Alya: Mr. Agreste lashed out on Mr. Stérn...
Marinette: But it wasn't his fault, it was Hawk Moth.
Alix: How come?
Alya: Well, guys remember Loup?
Nathaniel: The guy that broke into the Louvre?
Marinette: Yeah, but akumatized. He was wearing darker clothes, but had the tails and ears of a wolf.
Juleka: He sounds awesome. Like a were-wolf.
Nino: Yeah, that dude was kinda cool. I think he had claws and eyes like a....
Alya glares at them
Nino:... i'll stop.
Rose: So, what's gonna happen to Adrien? Do you think his father will do?
Nino: I don't like it, but think he'll make Adrien stay home.
Marinette: Hang on, look!
Adrien points at the entrance, where Adrien walks in inside. They all run towards him.
Nino: Hey, dude!
Adrien looks up, seeing them running towards them.
Nino: You alright?
Adrien: Yeah, i fine. Why?
Alya: Why? Because after last night, we thought something happened to you.
Nino: You are feeling okay, right?
Adrien: Yeah... i am.
Max: Hey, we better go. Classes are starting soon.
They all head upstairs, except for Marinette, Alya, Adrien, and Nino.
Marinette: You sure your feeling alright?
Adrien: I would be more concern about you. You probably had it a lot worse than me.
Alya: She's fine, but you not so much.
Adrien: Just forget about it, we'rr gonna be late.
They all head upstairs.
A few hours later.
Mrs. Bustlier's class just ended. Everyone gathers their things and head to their next class. Adrien walks out of the door, down the stairs and to the other side of the schook. Marinette, Alya, and Nino are observing him from the second floor.
Alya: He looks fine.
Nino: Yeah, Adrien's been acting like himself all day.
Marinette: Yeah, maybe we were worried for noth...
Suddenly, Adrien is straggling, struggling to keep his balance. He then collapses.
They all run towards him, as they group around them.
???: What is going on here? Out of my way!
Everyone moves back as Mr. Damocles makes his way.
Mr. Damocles: (sees Adrien, unconcicous) Oh dear... (faces everyone) What happened here? Someone better give me an explanation.
Marinette: He collapsed. Just as he was walking to the door, he was struggling to walk, before collapsing.
Mr. Damocles: I see... someone call an ambulance. You (pointing at Nino) help me get him to the nurse's office.
Nino and Mr. Damocles picks up Adrien, putting his arms on his shoulders and dragging him away. At that moment...
Nino: Hang on, i think he's waking up
They stop as Adrien begins to move. He opens his eyes, but they glow with a golden light.
Mr. Damocles and Nino lets go of Adrien as they back away.
Mr. Damocles: What is the meaning of this?
Adrien looks around.
Nino: Dude, you in there?
Adrien then runs, towards the door as everyone gets out of the way.
???: Stop right there!
Adrien stops as Renard and Loup lands in front of him.
Marinette: It's Loup and Renard. Everyone, stand back!
Renard: Don't be alarm. When your friend here touched the "apple" last night, he became awaken... but at a terrible price.
Loup: Boy, you must control yourself before you lose it.
Adrien gets in a fighting stance.
Renard: It's no use. Plan B?
Loup: I got it right here (patting his chest pouch).
Loup and Renard circle around him.
Renard: Return to your senses, Adrien Agreste...
Loup:... Before you lose yourself completely.
Loup and Renard tries to rush him, but Adrien dodges. Loup tries to grab him, but Adrien counters with a uppercut and knocks him back with a side kick. Renard grabs him from behind.
Renard: Argh! Now! I can't hold him much longer!
Loup: On it!
Loup reaches into his chest pouch and pulls out the orb. He then grips it, bright light erupts as Adrien eyes stop glowing and loses consciousness. Renard then gently lies him down on the ground.
Renard: (examining Adrien) It's worst than we though. The "syndrome" is in it's second stage.
Mr. Damocles: Enough! Explain yourselves!
Loup: I guess we can't hide it any longer.
Loup and Renard take off their hoods. Then they remove their masks, revealing them as Cooper and Jaune.
Mr. Damocles: The Stérn brothers?
Marinette: But... i don't understand. How? Why?!?
Cooper: We'll explain everything later. Right now, we need to attend to Adrien.
Nino: Why? What's wrong with him?
Jaune: He has a disease. A syndrome.
Cooper: When he picked up that orb, he interacted with it. He saw things... things no normal human could understand.
Jaune: Whatever he saw, it lead him to experience past memories... memories of his ancestors. At least one of them, anyway.
Marinette: Wait? What?
Jaune: Look, there's no time to explain. He needs treatment and we'rr the only ones who can give it to him.
Coopet and Jaune take Adrien's arm and lifts him up, before putting them around the shoulders and drags him away.
Marinette: Wait! Where are you taking him?
Loup: To the "site", where we'll cure him.
Alya: At least let us come.
Jaune: We can't! We don't have the time!
Alya: Then at least let one of us come with you.
Cooper: Very well... Marinette, come with us. Hurry, we can't waste any time.
Marinette picks up Adrien's bag and follows Cooper and Jaune. She then turns around.
Marinette: Don't worry, i'll text the address.
She then heads out the door and follows them to the GT-500. They put Adrien in the car.
Cooper: Get in.
Marinette gets in the back seat and closes the door. Cooper gets in the driver seat and sarts the car. Jaune gets in and they drive away from the school.
I hoped you liked it. Secrets will be revealed, find out what and how in Chapter 13: Enter the Past.
