All night, Adrien was working on the potion and the ingredients he found to brew them correcting in the bathroom next to Felix's bedroom. He hopes there's enough DNA heritage in Felix's blood, any of the ancestors that witnessed how or what his father died from. Anyone who was at his father's funeral is already dead now and no living person has passed this story to future generations. Except for Lila who has lived beyond her time the same way Adrien did.

Felix came into the bathroom, sluggish and tired at 6 am in the morning, "You're still awake?"

"I know you want me to sleep at night but I can't. I gotta know how my father died. You said your ancestors never told you or your mom anything about it" Adrien adds a hint of dead newt in the potion which turned the brew into green.

"Yeah, that's right. But are you sure this will work?" Felix grabs the comb to slick his hair back.

"I have to know, Felix. Lila locked me in a coffin and I never got released for over a century until a month ago the grave robbers released me. I never witnessed my father's death and one of your ancestors never passed their stories about him" Adrien said, adding his father's pocket watch he 'borrowed' from his grave.

"You better be ready for what you're gonna see then," Felix said.

"Which is why I need a DNA from you. In magic science or so, every descendant carries heritage. Even their ancestors' memories in blood" Adrien said, grabbing Felix's arm to bite.

"Wait! WAIT!" Felix stops him, "What if I still have too much heritage from my father?"

"You're the last descendant, Felix. Even if I want to use Lila's blood, she'll kill me. You're the only one with answers. Please. I can't do that from your mom or your grandmother. You're the young one here" Adrien begged for blood.

"Alright," Felix allowed him to bite him.

Drops of his blood drips into the formula and Adrien mixes it up in the potion.

The brew turns blue as it is done very well to mix the potion, "Okay, it's blue. I hope it's safe to sip it. Who knows how far in the past I'll see through one of your ancestors' memories. Even your great-grandparents" Adrien said.

"Give it a try," Felix said as Adrien then nodded and drank it.

His vision makes him see through one of the memories of World War 2 of Felix's grandfather in the war. He saw how he shot down several Nazi soldiers. But he wanted to go further back. He drank another one and it led him to another memory of World War 1 and it showed Titanic's sister ship Britannic sinking after colliding with a mine in the Mediterranean Sea. During the war, she was a hospital ship for soldiers but only over 30 people died by going into the still-moving propellers. He was shocked that the two ships never had such luck.

"Agh!" Adrien came back to reality.

"What did you see?" Felix asked.

"So many wars and death. So horrible. I need to get further. Give me another" Adrien panted.

Felix handed him more of the potion and Adrien drank more of it. The memory of his maternal aunt or late aunt who used to be alive, saw Gabriel on his death bed and the doctors confirmed that his heart stopped but his body was perfectly healthy, and no records of ever having a heart stroke, heartburn, or cardiac arrest. Not even a suicide can be the cause.

Adrien nearly has a grief sensation in his eyes but goes a little further to the dining table of the family and sees Lila with her family too. They all grieved at the disappearance of Adrien as well as Paw Noir. Unaware that Lila smirked evilly at everyone so easily to believe Adrien had disappeared or presumed dead.

The ancestor's memory was like a visual to see every angle of the memory but not the surroundings. Going back a little further, Lila slipped something into Gabriel's drink before everyone came to the dining table.

He realized he was poisoned by her, "No!" Adrien gasps in horror.

Lila killed his father to create an end of the Agreste bloodline. The will by his father was passed to the Graham de Vanily family if anything were to happen to him, they would carry on the legacy.

"Lila will suffer for this!" Adrien felt the rage in him.

Coming back to reality, Felix can see his ancient cousin looking very pissed off like whatever he saw in the ancestor's memory, it wasn't good.

"Whoa, whoa! What is it?" Felix asked.

"Lila killed my father with poison," Adrien said.

"What?! How?!" Felix asked in horror.

"By spiking his drink at my funeral" Adrien explained.

"WHAT?! No one noticed?!" Felix shouted.

"No one did," Adrien said.

"That psycho bitch!" Felix never felt so angry to believe she was a murderer to kill his ancestor.

"My father did not die naturally. He was murdered. That's why my father passed his will to my mother's side of the family. He knew if something ever happened to him, the Graham de Vanily family would carry on the legacy. Lila wanted to end the Agreste bloodline which included me and my father" Adrien explained.

"But you are still standing, bro. You're the last Agreste person" Felix said.

"That's not the point! Everyone thinks I'm dead! The entire Agreste family are all dead!" Adrien said, angry at himself that he was responsible for this mess.

"What are you gonna do?" Felix asked again.

"What my father and your father never did. Terminate her" Adrien said.

"I hope you know what you're doing," Felix said.

"I don't but she has gotten away with it for a long time ago. Her crimes are far expired and she's been in hiding like a coward to think she's won but she hasn't won yet. If she does the same attempt to you, it's the end of the Graham de Vanily bloodline" Adrien said.

"But you need Ladybug in this," Felix said.

"Yes, I know. But she doesn't know the real true Lila" Adrien said.

"But you do. You're the only one living who knows her more than anyone" Felix said.

"It's time I take the discussion with her," Adrien said.

"And how are you gonna do that? She almost killed your ass a few times and I wasn't there to save your ass but your lady did. You're a black cat with bad luck that will one day have bad luck stuck on your ass for who knows how long" Felix said, knowing that facing directly won't work.

"I meant that with Ladybug we can both defeat her," Adrien said.

"It's been a month now and no success. Your fangs still haven't gotten a bite on Lila's neck" Felix said sarcastically that he's never bitten her yet.

"I will not bite her, I will take off her head for this" Adrien said with vengeance.

"Like a monster you'll become" Felix can see lots of rage in him.

"She did this to me," Adrien said.

"Dude, killing her is like taking her place. Paw Noir was no killer in his days because he would never kill or the people would see him as a monster if he did" Felix said.

"But I'm Claw Noir now. Claw Noir is just a modern cat today, Paw Noir is from the past" Adrien said.

"Alright," Felix shrugs.

"Look, she's done more harm to me before she met you. You said she's been blackmailing your ass and your father did no shit" Adrien said.

"Yes. She did. But it's time to end it" Felix said.

"This time, she'll be the one to suffer as I have suffered in that coffin for over a century. She doesn't know the meaning of friendship or family. Hurting me and everyone doesn't prove she's the best" Adrien said.

"Of course" Felix nodded.

Much later, Ladybug was standing on the rooftops of Paris. She did spot one with a disguise and knowing the difference is that when it's a little windy outside, a disguised person would hold their wigs from falling

"Wait a minute" She saw the person run.

Ladybug was suspicious because she could see the person's hair moving up and down. So she swung down to confront her.

"Hello, stranger. You seem like you're going through something" Ladybug said.

"I'm just in a hurry," The stranger said.

"With what? A hair appointment?" Ladybug said, knowing well enough through the disguise, "Give me one good reason why you're trying to make me stupid like you did in school, Lila Rossi?" Ladybug was not stupid to fall for manipulation again.

"So you figured it out!" Lila took her wig off.

"I'm not that stupid when I see there's no dandruff or root hairline on fake hair" Ladybug glared.

"Too bad, well, you do know what I'm capable of!" Lila reached for her wand.

"Of course I do. For 3 years at school, you hurt a few students and you still got away with it. Especially lying to the public that I'm your best friend. Lying is hurting and hurting people doesn't prove you're the best" Ladybug swings her yo-yo.

Lila then casts one lethal spell at Ladybug but misses.

"LUCKY CHARM!" Ladybug summoned her charm, "A broom?"

"Really Ladybug? Is that all your lucky charm can do?" Lila sneered.

"Nah, just to sweep your face!" Ladybug smacks her with the broom.

"ARGH! WHY YOU!" Lila then throws a slashing spell at Ladybug, who flips over to dodge each of them, but one slashes at her wrist.

"She cut through the suit!" Ladybug realized.

"Hey! You bitch!" A familiar feline stopped the fight to get the witch's attention, "Get the hell away from my lady!"

"Well, if it isn't Paris dark knight!" Lila saw him.

"You killed my father!" Claw Noir bellowed.

"You figured it out?!" Lila gasped.

"Yes! And you're gonna pay for taking everything from me! With your life!" Claw Noir snarled menacingly.

"Should I be scared? You don't scare me with that nasty look of yours!" Lila cackled before escaping.

"Oh no you don't!" Claw Noir chased her and Ladybug joined the chase too.

Still angry at her for being a deceitful liar but also for ruining everyone's lives with corruption.

"Don't let her get away!" Claw Noir ran faster.

"She's goddamn fast!" Ladybug tried to catch up. She then threw her yoyo at Lila and tied her legs.

"Good shot, milady. I can't touch her but you can!" Claw Noir said.

"Yes!" Ladybug pulls Lila in and stomps on the wand.

"No! Let go you brats!" Lila struggled.

"Now do you get how it feels when you annoy me a lot back then?! You should've killed me when you had the chance over a century ago!" Claw Noir said but then something was off when her scent was nothing like he remembered, "Wait a second" Claw Noir touched her arm and nothing happened, "It's not her! It was a decoy!"

The cloaked illusion changed her to Chloe all along.

"CHLOE?!" Ladybug exclaims in shock.

"Better luck next time!" The real Lila laughed before escaping into the city.

"Fuck!" Claw Noir punched the wall next to Chloe.

"You two planned this?!" Ladybug furiously grabbed Chloe.

"She promised me to get what I want! You two ruined my life for this! Both of you deserve to be in jail!" Chloe yelled at them obnoxiously.

"No! You should be for mistreating everyone and abusing your power!" Ladybug retorted.

"I gave you one chance but now my patience has expired! Take her to her father, milady. She's too dangerous here to be used as a pawn" Claw Noir growled.

"Gladly I will, Kitty" Ladybug drags the ranting Chloe away.

Claw Noir knew that the murderer was two steps ahead of him and it won't be easy to get close to her or touch her. It was only a matter of time until she tried to make the same attempt on Felix and it would be the end of the Graham de Vanily bloodline. So he had to go back before she made it there. Morphing into a bat he flew back.
