Somewhere in New York. Abigail was woken up by her kwamis, Airo, the Dove kwami and Parru, the Peahen Kwami.

"C'mon! C'mon! Abby! Time to go to Paris! The airport is waiting for you!" Parru jumped on Abigail's torso constantly.

Abigail sighed, "later.. and stop Parru, you're gonna make me throw up."

Airo slapped Parru, "you heard her! Stop bouncing! It's too vulnerable!"

"Hehe," Parru laughed sheepishly as she halted. "Sorry.."

"Abby, time to go to the airport. Paris is waiting for you," Airo calmly said. "Don't forget that Natalie wanted you to come there because she wanted you to stop Hawkmoth."

"And that's when you found me!" Parru obtruded.

"No, she didn't!" Bellowed Airo. "That was before Natalie wanted to send her to Paris! She delivered the Peahen Kwami first, because she said, it was something to remember her mother by!"

"Aww, how sweet!" Parru then cried. "And wahh!! Why did Master Aurora even have to disappear?! I miss her already!"

"Guys, please don't talk about my mom.." Abigail covered her face with a pillow as the sun shined down to her hair. She was living in a luxurious apartment that her father stored for her, of course.

"We're sorry, Miss Abby. We won't do it again," Airo said, elegantly bowing down. "But seriously, please get ready for Paris. Natalie's been waiting."

"Guys, I get that Natalie's been my mother's friend and all that. But I want to give up on this for a second," Abigail said. "I know that I have to come back to Paris for a mission, but man! I'll do it later!"

Parru rolled her eyes, "oh, don't be a lazy bone! At least you get to see Adrien again!"

"Nah, Adrien's just a stubborn and jokish child like before. Don't forget the reason of why I was sent to New York!"

"Abby, I know that Adrien and you got a fight since you guys were 13." Airo said. "But come on, you're 16 today and he is too! He's your twin brother! I'm sure he's changed today ever since your mom...died."

Abigail sat up, "I hate to be a blunder, but you shouldn't talk about a dead person." She glanced at Airo and Parru. "I want you guys to shut up."

Her eyes flashed glowing neon-blue as the kwamis reflected it, and they've done of they were told to. This was clearly half of Abigail's power, Oraculum or to be said it more clearly, Authority. She headed to the bathroom for a shower as the kwamis were silent.

But someone called, her phone rang. Abigail picked it up, "Dove.. may I speak with you honestly?" She recognized this old voice.

"Yes, Master Fu.. what is it that you ask?" Abigail sounded serious.

"It's time.."

Back in Paris, Marinette was running again. This time doing it while reading a book, "let's see! Let's see! Uhm, uhh.. atom--"

"Marinette! You're reading the book upside down!" Tikki peeped out of Marinette's little purse.

Marinette squeaked in embarrassment and turned it rightside up. "An atom is the smallest particle of an element that can exist either alone or in combination--"

"Marinette, don't expect that you'll get the whole thing in your mind by just reading it!" Tikki alarmed. "And slow down, if you--"

Marinette bumped into someone, her book was tossed up in the air while that somebody's text book did as well. The books swapped places.

"Oh, gosh! I'm so sorry!" Marinette apologized. "I'm such a klutz!"

"It is my fault for not looking of where I was going," a familiar voice said as Marinette's eyes shrunk.

It was Adrien, suddenly Marinette scowled at him. "Oh, it's you."

"And if it isn't Marinette Dupain-Cheng. My long weird-weird enemy, still mad 'bout that gum incident?"

"Not as mad as I've found out that you were Chat." Snapped Marinette.

"And I found out that you were Ladybug," Adrien rolled his eyes. "It's sincerely not my thing to be impolite, but I never really liked you, whether as Marinette or Ladybug."

"Pfft, same here, though." Marinette said, "and please watch where you're going. Are cats blind these days?"

"Uhm, I'm not a real cat." He recovered and handed out a hand to Marinette in a gentleman's manner.

"Seriously?!" Marinette asked, she slammed his hand away and got up by herself. "Are you really that dumb?!"

Adrien was screaming for rage inside, "pardon?" His eye twitched with rage.

Before Marinette could say a word, "I couldn't help but ask, are you two an item?" A new voice popped in as they turned to see Madame Dove, a dove and peahen superhero. Floating ground, she wears a a peahen suit, with a silky peahen-patterned long skirt. High tall peahen-patterned boots. She has a white dove-themed sling bag hunged on her shoulder and a peahen-themed fan wrapped around her belt. She wore an amulet, it's pendant was prismed and the design had white sparkling diamonds and a pair of little wings wrapped around over it. Her golden hair was shined brighter than the sun, her eyes were sparkling blue. Her skin was slightly tan and her hair was back-lengthed, it was long and straight.

"Tch, with this gal? No way!" Adrien snarled.

Marinette did as well, shaking her head. "Same here!"

"You two are Ladybug and Chat Noir. Am I correct?" Dove asked.

Marinette's eyes were wide open, "how did you--"

"First off, nice to meet you and blah blah blah. I'm Madame Dove, a dove and peahen superhero." Dove exclaimed with glee. "And you two will be getting MARRIED!"

"What?!" Both of them freaked out.

"That's dumb," snapped Marinette.

"Preposterous," Adrien said. "Seriously? Are you kiddin'? This isn't funny,"

"This is true, imp." Snapped Dove, "I'll need you to be careful and close that mouth of yours for a second so I can talk! As I've said before, you two will be getting married and I'm deeply serious."

"Just who are you exactly?!" Asked Adrien.

"Abigail. Your twin sister." Said Abigail as Adrien's eyes wided. Marinette's eyes did as well, almost bulging her eye sockets.

"You have a twin sister?!" Marinette asked, freaking out.

"Long story." Dove sighed.

"This is...Abigail?" Adrien asked, he glanced at her from head to toe.

"Of course, I am. Why? Got a problem with that?" Dove snapped, frowning a bit.

"Yep, you're Abigail, alright." Adrien examined his sister, "Abigail, you look different!"

"Yes, I am. Why? Is it bad to even change?" Abigail glared at her brother, gripping on the strap of her sling bag. "You look..nice in way too, I guess. Or is it just another figment of my imagination?"

"Strong tounge, tall posture, mean glare, snappy tone." Adrien examined his sister. "that's not the Abigail I know. She wasn't that mean when we were 13 and since we're 16, I was hoping that she would be another premature person like father!"

"And you're another weird person," Dove snapped. "So you're a Chinese person?" She smirked at Marinette. "I like this girl, so you sure that she isn't your girl friend or whatever? Huh? Adri?"

Adrien frowned, "tch, her? We've been in a fight ever since the first day."

"Uhuh," Dove said. "Well, it's me, Abigail, your sister. Isn't this a melodramatic rekindling? Aren't you gonna embrace me or something?"

"I still have a few questions though," said Adrien. "First off, what are you doing here? And what does this even mean?!"

"You two will be the Miraculous Duo!" Dove proclaimed.

"Huh?! What does that even mean?" Asked Adrien.

"I've read that in Master Fu's book before, but what does it mean?" Asked Marinette.

"A child shall bring end to the war between good and evil that is stored deep within the Miraculouses. And that child is the child of the Miraculous Duo, the Savior." Dove said in a serious tone, then abruptly explained, smiling from ear to ear. "That means you two will get married and have a baby."

"Uhh--" the two gaped and stared at Dove while she smiled proudly.

"Congrats!"

"Whoa, whoa, whoa, whoa! Have a baby?! With her?!" Adrien blushed as he gestured Marinette.

Marinette scowled at him, "what're you blushin' about?!"

The bell then rang, "welp, that's the bell. See ya!" Dove smiled warmly as she flew away. "Let's meet after school!"

"So we're..destined to be together, huh?" Adrien asked, looking away at Marinette, surprisingly blushing.

"Can it. Now to the school, we don't have all day.." Marinette walked up to the staircases as Adrien followed.

"Hey Marie! What took you so long?" Alya appeared in front of the halls, she saw Adrien. "Oh, and you've got Adrien with you. I thought..you guys never got along,"

"We did and we just ran into each other," Marinette crossed her arms. "Nothing unusual happened, that's all. Oh and I have to..get home early,"

"What? Why?" Alya asked.

"Her mother wanted her to assist on decorating their bakery." Adrien proclaimed as Alya gave him a suspicious and curious look.

"How do you know about this?" Alya asked. "You're not..another Nathan, are you?"

"Nathan?" Adrien raised a brow. "Why would you say that?"

"Nathan had a crush on me," Marinette said.

"Oh, that's..fine," Adrien gawked. "And I just knew, that's all."

"Sure, whatever. I'll leave you be," Alya rolled her eyes and dragged Marinette upstairs to the class room.

Marinette sat on her seat as Alya sat aside her. "Thanks for drawing me away from him, Alya. He's so annoying, and stubborn!" She said as she placed her back pack down.

"Uhm, no need to be rude and all, but you should give him a chance." Alya said as they watched Adrien come in. "If you keep acting this way around him, you'll be losing allies and friends."

"Hmph! What do I even need a friend for?" Marinette huffed. "I only came to school to learn, not make friends!"

"Uhm, girl. I'm your friend, your only friend." Alya said, "I'm right here, so.. don't say anything cold,"

"Sorry,"

"Students, we have a new transfer student." Ms. Bustier said.

Marinette and Adrien turned pale as they gaped while their eyes wided.

"What the?" Alya adjusted her glasses, "is it me or does she look like somebody?"

"This is Abigail, Abigail Agreste." Ms. Bustier explained, "obviously Adrien's twin sister and a daughter of Gabriel Agreste. She'll be transferring in this school, be good to her everyone! Abigail, you sit in the back with Lila, is that fine?"

"Yes, Ma'am, it's fine." Politely Abigail answered and nodded, heading to the back.

Taking a last glance with a smirk on Marinette and Adrien's shock faces.

-:-
-:- -:-

"Abigail! What the hell?!" Adrien freaked as Abigail folded her arms.

"What are you doing here?" Marinette asked, they were in the Empty Hall. "I thought you only came to us just to inform that..we're this Miraculous Duo thing!"

"I did," Abigail drank water, using a drinking fountain. "And it is my priority to protect and watch over you, you are Paris' only hope."

She wore a long-sleeved white jacket like Adrien's, underneath is a black dress shirt. She wore a white-slitted cupcake-like skirt. She had a light blue shoal hung over her shoulders, she had high tall white boots. She wore a pair of white earrings, while her hair slunged over her shoulder. Her hair was obviously curly with golden locks, she had lime green eyes that's very similar to Adrien's or Chat's.

"Look, I agree with you baby-sitting us or something. But I can't take it but ask," Adrien said. "Why?! Why us?! Destined to be together? Have a baby?! Are you crazy?!"

"That's not crazy, there's actually nothing I can do." Abigail said, "I saw it from an oracle. It said the prophecy shall be fullfilled, if two souls shall give birth to such will. For a child given birth by the symbols of adversity and serendipity. All will bow down to the charm of calamity. Understand?"

"Nope, no idea." Marinette snapped. "Nu-uh,"

"I don't get anything at all," Adrien said.

"Just listen to me!" Abigail's eyes flashed glowing blue as the two relfected her eyes and became silent. Her hair was levitating as she threatened, "don't you realize that you two have done nothing but argue all day?! Your child will have a god-like strength once it's given birth, it would be the source and the weapon to end all the darkness that a miraculous has. Don't you realize that it's not just Hawkmoth out there?"

"You may be right, though," Marinette bitted her lip. "B-But him? Me? A duo?" She somehow stuttered.

Abigail rolled her eyes, "why are you two so shock about this? It's your duty as a superhero, do it. Plus you guys have been crime-fighting superheroes since then. Why not just give it a shot?"

Marinette and Adrien glanced at each other, Adrien lightly blushed as Marinette huffed and looked away. "Uhh.. I mean.. if you just found out that you were destined to be together with a person you hate, what would you do anyway?" Adrien asked.

"Simple," she retorted numbly. "I'll just accept it, it is my duty and I do have a annoying, stubborn, hated, but trustworthy partner back in New York and we were almost the ones who were supposedly the Miraculous Duo, but since Fu had a better idea, things changed. And now, I'm here! Right in front of the duo."

"M-M-Master Fu... he-he's the one who sent you?" Marinette twitched an eye, gripping on her hair. "Seriously?!"

"Hey, there's nothing I can do. Fu's orders though," Abigail clasped on her hands and began pushing the duo somewhere. "Now, let's go! I'm taking you somewhere! You guys open?"

-:-
-:- -:-
-:-

"Uhm, Abby." Adrien rubbed his nape, "y'know, when we said yes, we're open. This..was not what we had in mind,"

"I mean, the cafe? Seriously?" Marinette asked as herself and Adrien were forcefully sat together, too close.

"Oh, c'mon!" Abigail exclaimed with glee. "It's always like this in the previous days! The cafe is the most accumulated thing for couples to know each other better!"

Adrien and Marinette's faces were numb, "we're not your puppets, Abby." Adrien said.

Abigail shunned him as she took a bite from a crepe, her eyes wided. "HOO~~" she blustered too loud that the costumers and staffs turn to her. "IT TASTES SO GOO--" Adrienette shoved two spoons of their heart-shaped crepe on her mouth for her to shut up.

"Pipe down. You should really do something about the way you talk." Adrienette simultaneously snapped. "Suck. It. Up. It's such a turn-off."

Abigail swallowed and giggled as she pushed the spoons away, "I knew it! You two were the ones fitted to be the duo! You guys even move in unison! Almost relatably! I mean, in a spouse way to be exact."

Adrienette's eyes wided as they dropped the spoons. "A-Abigail! Don't say such w-words!" Marinette blushed, looking away.

"So, here's a task given by Master Fu!"

"Huh? Fu made contact with you?" They both said in unison, obliviously.

"Hey A-Alya!" Nino called as he made his way out of the school, "have you seen Adrien?"

Alya paused, "what're ya asking me for? Marinette forbid me to talk to him or even look at him,"

"S-Sorry, I was just wondering!" Nino said. "I feel so lonely.. hey, wanna hang out? I heard there's a new cafe nearby."

Alya swiveled to him and tapped her chin, "Marinette did say that I wasn't allowed to hang out with Adrien, but you? His best friend? Hmm, probably it's fine. So, yeah, I'll come with!"

"Nice!" Nino grasped on her wrist and dragged somewhere.

Abigail smirked, as she had the two tremble. "D-Do we really have to do this?" Marinette queried.

"Yup," Parru popped out, "it's an honorable thing!"

"C'mon, you two! We don't have all day!" Abigail overjoyed, as she rested her cheeks on her heels. "They say if lovers feed each other, they'll feel complete happiness!"

Parru bounced up and down, "a bliss!"

"Go on," Airo suddenly had interests with this.

"S-S-Say ahh.." Adrien blushed as he reached out a spoon, filled with the crepe's asunder.

"A-Ahh.." Marinette was very red as she was trying her best, but she couldn't take it anymore. She sat up, slamming her palms on the desk. "I can't take it anymore!"

"Marinette?" Alya peeped as Abigail's eyes turned glowing blue.

"Disappear," she then faded away without a trace.

"And.. Adrien?" Nino popped out behind Alya as the two had their eyes wide open.

The duo freaked out, "th-this isn't what it looks like!" Marinette alarmed.

"Yeah, yeah! My sister was the one who planned all this!" Adrien glanced at across his seat to see no Abigail. "Huh? Where'd she go?!"

"Look guys, you don't really have to pretend." Alya smirked, "we know your secret."

"S-Secret?!" The duo was all red.

"Yeah. You two..." Alya layed a finger on their noses. "..are dating! And your hate for each other was only a facade, so people would be oblivious!"

The duo blinked and started to play along, "y-yeah, yeah! That-That's right.. I guess," Adrien laughed sheepishly.

"Welp, I'll leave you lovers then!" Alya dragged Nino away, "you guys seem to need privacy!"

"H-Hey! I thought we were going to hang out on the cafe?" Nino queried.

"Yeah, but they need privacy!"

"And I care because..?" They left the cafe.

Abigail giggled as she abruptly reappeared, resting a heel as she leisurely rotated her glass of smoothie on a circular motion. "Hmmm.. finally agreed that you guys were a couple? Eh?"

"No! We just did it, so our identities won't get caught." Marinette snapped.

"Now, can we leave and just start this tommorow?" Adrien asked. "Father's gonna get upset."

"Hmm.. you may be right," Abigail smirked. "But before you leave, I'll have you do something."

"Huh?" Both of them said in unison.

Abigail smirked as she had the duo walk with each other, they felt really uncomfortable. They were all red as a tomato though, they were trying their best to hold each other's hand.

"Do we really have to do this?" Marinette asked. "Just remind me of why, exactly?"

"Yes, and it's because you guys gotta learn to move on to the next stage."

"Look, I don't care about this stage-stage thing. But it's so awkward--"

"Just keep walking and shut up," Abigail snapped as she looked through her phone and glanced at the stumbling duo. "And don't be a wimp, Adrien! Hold the girl's hand already!"

Adrien flinched as he trembled, reaching out his hand to Marinette's. But he then whined, "gah! I CAN'T DO THIS!"

Abigail sighed, "that's it. That's it for now, you can go home.. we'll deal with this tommorow."

"Thanks, Abigail." Marinette sighed in relief, "you're.. kinda fine, in a way." She left.

"Uhuh?" Abigail raised a brow, "you go first, Adri. I've got business to do."

"Sure, do what you want." Adrien rubbed his nape as he walked away, mumbling. "Just can't believe dad sent you back so early.. I mean, three long years? Wait.. is that even early?"

"Just go home, you simpleton." Abigail rolled her eyes.

"Yeah, yeah. I'm on it." He left.

Abigail's phone rang, as Airo and Parru gazed at her. She picked it up and answered, "yes? Yes, Fu. They know, yeah, kinda hard. They won't get along," she sighed, "I know, I know. I promised myself not to be a push-over, but they're really pushing my limits and--"

A scream then was heard, Abigail looked up to see a pair of twins. A boy and a girl, the girl was embraced with flames while the boy was embraced with snowflakes.

"We're the elemental twins! And we're the most powerfulest duo in the whole world!" The two simultaneously announced.

Abigail was standing right in the corner, "sorry, Fu. But I've got work to do, I call you back after the fight," she didn't take her eyes off the akuma as she ended the call by a press on the screen. "Airo! Parru! Wings Spread!"

Okay! I'm done with the first chapter! I hope you guys like it! Sorry if I haven't included any crime-fighting actions yet. I'm thinking my best, actually. Please vote beneath and I'll be seeing you guys on the next chapter! Byeeeeee!
