A/n: someone commented sarcastically they think that Chat should kill his father on how horrible his father treats him. And to that, I have six words: be careful what you wish for.

Marinette's POV

The wind blows through my hair. I pull my scarf up to my nose, and I rub my hands together to create at least some warmth. I stand outside, waiting for Chat Noir to walk out. If all goes according to plan, he should come outside un-akumatized. But, even though I'm the freaking guardian of luck or whatever, Chat Blanc walks outside instead.

Crying.

I rush to him, and hold my arms out. I give him a tight hug. He hugs me back, and I feel him tremble. He's cold, shaking, and alone.

"Please de-akumatize me, princess. I don't want to be cold anymore," he whispers in my ear.

My heart is struck. I can't believe someone would make their own son go through this. How could someone call themselves a father and put their own child in direct danger? How could someone call themselves a father and make their child feel hurt because of them? How could someone call themselves a father and make their own child deal with the struggles of the world all alone? What type of monster uses their own child as a toy in their great scheme of taking over the world?

"I've never dealt with an akuma who's asked to be de-akumatized! W-What happened?" I ask, pulling away.

He holds himself and trembles from the tears falling down his cheeks. "He said he would bring back my mom even if that meant I had to die."

"Excuse me?! Why would she even want to stay with your father if he let you die in exchange?!" I scream.

He opens his mouth to say something, but nothing comes out. He trembles and collapses in the middle of the Paris street. He's so hurt; so alone.

"I can't do this anymore. I feel so alone. You're all I have Marinette."

I sit next to him on the warm cement. "Don't say that, that's just the akuma talking."

"The akuma akumatized me because of my feelings, right?! I could never tell you this when I was Adrien, but now because I'm Chat Blanc, I finally know my true feelings!" He shouts, breaking down.

I squeeze him and try and calm him down. "Chat, please!"

"He's going to turn the entire city of Paris into vampires tonight. If he does that and you leave this world, I won't have a reason to live anymore!" He sobs.

"Chat..."

"Marinette, I wish things were the way they were before! I hate being a vampire! I wish I never turned in the first place! I hate my father!"

"Chat calm down..."

"I wish I was never Chat Noir!" He screams, his voice cracking from the pain.

I rub the back of his head. "Shhh, I know. I have a plan."

"What's your plan?" He asks, pulling away from the hug.

"I can't tell you or you will never let me do it."

His ears perk up. "Princess, now you have to tell me."

I shake my head. "Come on, let's go home."

"No."

"What?"

"No. I'm going to make Hawkmoth pay."

I turn my head in shock. "Huh?"

He stands up and I see his expression quickly drop to a blank face. "I'll... I'll trick him. Yeah. I'll trick him and I'll get the miraculous instead, and wish for him to be dead."

A chill runs down my spine. "Ha-ha Chat, very funny. Okay, lets go."

"No," he states, "I'm not going to your place. I'm going to turn the city of Paris into vampires tonight and then I'll be the one to get the miraculous instead of him."

"Yeah, whatever. Here, let me de-akumatize you. I just need to transform really quick..."

"No. You aren't listening, Dupain-Cheng."

He never calls me by my last name.

"Chat, I'm serious. That's a seriously evil and bad idea. Don't joke around."

He throws his hands up. "Why not?! He would finally get what he deserves!"

I stand up, tense and scared. "Luka and I are the only miraculous holders left, not counting you! That means you would have to beat Luka and I to get what you want!"

He frowns. "I thought we were a team. You're all I have left, Marinette."

I back away. "You're still an akuma, Chat. I can't trust you no matter what you do. Let's just get home so I can de-akumatize you."

"Why do you always bring up the akuma? I'm so much more powerful in this form!" Chat argues.

"You just said you wanted to be de-akumatized! Why are you switching up on me like this?!" I shout in confusion.

"That was before I made my plan. Now I know what I'm doing. I'll use the vampires against Hawkmoth tonight and show him the amount of pain he's made me go through. Let's call it a plane of revenge."

I glare at him. "The Chat Noir I know and love wouldn't do this."

He tilts his head and smiles. "Too bad I'm not Chat Noir. I'm Chat Blanc."

Luka's POV

I'm soaring through the city terrified of what might have happened to Adrien. His dad took him away, and from what I heard from Marinette, he might go through with the plan. The only problem is we only planed out the first part: Adrien needs to trick Hawkmoth into thinking we're on his side. We never talked about how he's going to get there, or how far he should go. I'm deep in my thoughts when suddenly Marinette calls me.

"Luka! Oh my god, Luka!" She sobs through the phone.

I land on a tall building in the sky and frantically answer her. "What's wrong?! Did you find him?!"

"Yes!"

It feels like a million tons have been let of my chest. "That's great! Oh my god!"

"N-No!" She interrupts through her tears. "He's... he's been akumatized!"

My eyes widen and I feel my heart sink in my chest. "...What?"

"He's been akumatized into Chat Blanc! He must have wanted to prove that he was really on Hawkmoth's side, and went too far! I thought I could talk logic to him, and I almost had him on my side, until he got so worked up on Hawkmoth's revenge."

"He is an akuma, after all. Akuma's don't think about anything but themselves and what they want. You can't really talk logic into them," I explain. "Wait, whats this revenge plot he's talking about?"

Marinette doesn't say anything.

"Marinette?" I ask.

"He's going to turn the whole city into vampires. Even including you. You are what is called a dormant vampire. You think you have your vampire powers under control, but you really don't. Chat and Hawkmoth have the power to awaken your vampire instincts inside of you and you would have no control over it."

I gasp. "So he can turn me evil, just like that? All because I'm... what's it called... a dormant vampire? So that means there's more of my kind out there..."

"Yes. He's going to use that as leverage. We're going to have to give him our miraculous to him if we want the city of Paris to go back to how it was, without all the vampires."

"So Chat Blanc going to get our miraculous and use the wish to wish for revenge?" I ask.

"Yeah. He's going to try and do it by tonight," she nervously explains.

I gasp. "Tonight?! But it's 5 o'clock in the evening right now! That's only a few hours away from night!"

"Which means you only have a few hours of being in control."

Silence. I can't believe this. Not only is Adrien akumatized, but he's going to try and take over the whole city. He's going to try and steal our miraculous too. If Marinette and I don't have a plan by this evening on how we're going to beat him, then I'll end up helping Chat too, whether I like it or not. He'll be able to turn on my killer vampire instincts, just like that.

"Okay, we first need to prepare," I explain through the phone. "Let's meet at your place and talk through our new plan."

"Alright. See you in five."

She hangs up. I slip my phone into my pocket. Before I start making my way back to Marinette's place, I remember what it was like when I was akumatized. It was dark. I didn't care about how others were impacted, I just wanted my way. I didn't care about anything else. I understand Marinette trying to befriend Chat, but knowing how the akuma messes with your brain, he won't want to be her friend unless she's on his side twenty-four seven. Akumas are selfish. They only think about themselves.

I arrive at Marinette's place through the window. I slip in her room and notice her sitting on her pink bed. I de-transform and walk across her wooden floors to get closer to her. As soon as she sees me, she parts her hair to the side.

"Woah woah woah, I stole from the blood bank recently. I don't need any blood," I say, waving my hands and looking away.

She laughs. "Look, if you're gonna turn evil, I would much rather you be evil and full, and not evil and hungry for blood."

"You sure?" I ask, taking a step closer to her.

She nods.

"Don't need to tell me twice!"

She giggles.

I place my hangs gently on her neck. She takes a deep breath. I slowly and carefully sink my vangs into her neck. I be careful to not tear her fragile skin. I only need a limited amount of blood, so I don't need to rip into her skin. I taste her sweet blood on my tounge, and even though I itch for more, I know I can't risk hurting her. I pull away and wipe my mouth. She sighs from relief and starts to walk to her bathroom to clean herself up.

"I'm going to go get some bandages, okay?" She asks lightly.

I nod, and I'm about to go back to my business, when suddenly I notice the other side of Mairnette's neck that she didn't let me see. It looks bruised.

"Marinette... your neck..." I mumble, taking a temp towards her.

She whirls around on her toes, and brushes her hair in front of her neck. She gives me a forced smile.

"Oh, it's nothing!"

I frown. "It was Chat Blanc,  huh?"

She swiftly turns around and ignores me, and bandages herself up in the bathroom.

"We only have a limited amount of time left. I suggest we both transform and storm into Agreste Mansion," she explains.

"What time do you think he'll activate the dormant vampires?" I ask.

She sighs. "He said tonight, but I don't know if that means 6 o'clock, 8 o'clock, or 12 am."

My chest starts to hurt. I sit on her bed and pull my knees to my chest. I try not to cry thinking about the fact that tomorrow I won't be myself, unless my plan with Marinette works.

"Let's go now," I suggest, getting up from the soft bed.

"W-What? Now? Our new plan isn't even all the way finished yet!" Marinette stutters.

"I want to leave now. Let's just storm the mansion, cure Chat Blanc, and take away Hawkmoth's miraculous."

Marinette rolls her eyes. "Luka, it's only six. We need time to form a plan before anything, and that plan you suggested doesn't sound very reliable."

"I don't want to turn into a true vampire!" I shout, fear rising in my voice. "I won't be able to control anything! I could kill you! You would have to face Chat, Hawkmoth, and myself all on your own!"

"I've beat you once, and I can beat you again. Trust me," she replies, walking out on her balcony.

I lay back on the bed, exhausted from arguing. The afternoon light fades in the sky, turning it into an orange color. Birds fly across the sky. I feel the hot wind coast throughout Marinette's open windows. I rub my forehead and sweat beads drip down.

"Mari, can you turn the air conditioning up?" I ask, changing the topic. "It's too hot."

She twirls around and leans on the balcony fence. She slowly brings her scarf up to her nose and I notice her breath in the air.

"Psh, what do you mean? It's 29 degrees out!"

I sit up in the bed, and sink into my puddle of sweat in the mattress. "Ha-ha, very funny. Look, just turn the ac on. I'm sitting in my own sweat, Dupian-Cheng."

"Well, Couffaine, incase you don't have eyeballs and don't remember which freaking season we're in, it's fall. You shouldn't be sweating," she says, laughing.

I try to stand up to argue with her, but my head starts to swirl. I immediately collapse back on the bed and reach for my head.

"Marinette, my head is pounding."

Her face drops.

I squeeze my eyes tight as my head screams in pain. My head is spinning, and my vision is blurring. I feel like I want to puke. I feel so hot that I'm sweating. I try and listen to what Marinette is saying, but I can't hear a thing. All I can focus is on the pain. The excruciating pain. I need it to stop.

And then it hits me.

I'm transitioning. I'm transitioning into one of Chat Blanc's vampires.

"Marinette..." I whisper. "Marinette please!"

She dashes over to me, and holds my head on her lap. "I- I don't know what to do! I thought we had more time!"

I have tunnel vision. My world is moving in slow motion. Ignoring the pain in my head, I reach over and hold my hand on her cheek.

"Please, Marinette, Promise me." I whisper, trying to stay awake. "Promise me that if I try to hurt you... you'll kill me."

Her face goes pale, and tears start to form. "Luka! No Luka, I can't do that!"

I shake my head and try to show her I'll be okay. "Please, Marinette."

"Luka! You're my friend! I can't do that!" She sobs, with tears racing down her cheek.

I smile. "You are an extraordinary girl, Marinette. Clear as a music note, sincere as a melody. You have been the song I hear in my head since we first met. I won't let anyone hurt you, not even myself."

Tears continue to fall, and I wipe them off her cheek. "Luka..."

"Promise?" I ask.

She finally nods. "Promise."

With that I stop fighting the pain in my chest, and I surrender to the darkness forming in my mind. The darkness rushes through my body. I feel it flow through my veins. It twists and turns throughout my system, until I feel numbness throughout my entire body. I feel the cold, empty, shallow feeling in my heart. I sigh.

How alone I felt was the last thing I remember before my emotions shut off, and I forgot who I was and who I wanted to become. That didn't matter now. I am a vampire. An akuma. My mind and soul belongs to Chat Blanc, my leader.

And I will obey.
