Its unknown how Felix will react about knowing who Lila was and what she did. He once met on the train in Adrien disguise in Risk episode but he didn't know much about her but I think Lila probably knew Adrien had a cousin and sent the video of him to Gabriel in Felix episode. I suppose he'll know from Adrien about the school and things changing around in Paris after fighting back Queen Mayor, I just hope he doesn't make a deal with her the same way he made a deal with Shadow Moth. Knowing what he faced and learned the hard way, he definitely can't go back to his old mischief ways since he wears the peacock brooch in honoring his late aunt.

Unlike her, Felix has a conscience and faced his mistake the hard way in Emotion episode which indeed he did have human feelings. He was just misguided and broken from his childhood because of his late father Colt Fathom treating him so bad it nearly cost his lifeline. Cerise did not because she doesn't care who she hurts and only wants to get what she wants, even at the price of making major mistakes in the past, the consequences will eat her up. 

--------------------------------------------------------------

Ladybug never thought her Adrien was the cocky and pun master feline this whole time. Whenever Adrien disappears, Cat Noir shows up. When Cat Noir never shows up, Adrien is always here. Like the time with Gorizilla, she had to protect Adrien but Cat Noir didn't show up. When fighting Style Queen for the first time, Cat Noir was a no-show because Adrien got hit. And when Mr. Pigeon had everyone and Adrien turned into black pigeons, Cat Noir was a no-show. And finally, when facing Moolak, Cat Noir did not show up because Adrien was forced to make public appearances on TV.

"It all makes sense now. And I threw you in that trash bin!" Ladybug gasps in horror upon realizing this.

"Yup. I nearly vomited in there" Adrien chuckled.

But Ladybug wasn't so amused, "I was angry that I got so annoyed! But obviously, that wasn't very ladylike of me!"

"Now you know why I make jokes and puns as Cat Noir. As Adrien, I was stuck being perfect my whole life. As Cat Noir, it makes me feel free and be true to myself. Adrien may be a sentimonster to obey orders but Cat Noir is wild and untamed as he enjoys freedom" Adrien explained why he has different double lives and personalities.

"Here goes nothing. Tikki, spots off!" Ladybug detransformed.

"Marinette?!" Adrien gasps.

"Surprised or definitely hate me that I feel like I'm like Lila to you?" Marinette looks away.

"You're nothing like Lila, Marinette. But I understand why our identities can't be revealed" Adrien said.

"We lied to each other, to our friends and family. We are becoming exactly like Lila" Marinette said.

"Not with ruining lives by lies," Adrien said.

"But I almost ruined theirs to hide the truth with my guardianship. I ruined Master Fu's life, I ruined Chloe's because I could not give her the bee miraculous ever again and she now views Ladybug as the bad guy. I ruined Lila's life by getting involved because I did not want her lying to you. Life is not easy, Adrien. We may think we are good people but sometimes we can be bad people too" Marinette said, looking down at the city.

"Princess, you do know when people say they fight fire with fire," Adrien asked, hugging her from behind.

"How can you forgive me after all I've done?" Marinette asked.

"Because I know you're pure of heart," Adrien said.

"No one is pure heart, Adrien. We all balance between good and bad. And I know what you mean by fighting fire with fire. We all get burned when there are no good guys or bad guys" Marinette said, nearly moaning from the biting kiss on her neck.

"Yes. The future will be no less different, even with Monarch dead and Cerise imprisoned there are more threats" Adrien said.

"And everything we have been through, all I ever wanted was to be a normal girl with a normal life but I could never be that when your father plays Satan than a God to corrupt everyone's pain into evil," Marinette said.

"So do I, even as a sentimonster," Adrien said, holding her hand, "But love conquers all hate"

"And I'm sorry you lost your father, Adrien. But death is something he can't escape from because he wasted his life for nothing. He wasted so much that he couldn't see what he had until it was gone. He was your only parent" Marinette apologized.

"No, my mother never wasted her life by having me. She never did anything selfish to save her lifespan. She had all the time and every moment to raise me because that was her dream. Even if the price to pay was her life by having me but she accepted her fate because she did not want anyone's life to be taken away because of a mistake she and my dad made to create me. The bequest she left me was her music records I kept" Adrien explained why his mother was too kind-hearted.

Marinette took in everything Adrien said, "You really are like her"

"And that's why I had a loving mother to raise me right. And that was also her request before she was supposed to die" Adrien held out his mother's phone of her recordings.

"There will come a time my little prince will find love the same way I found love at first sight with Gabriel. Adrien is growing more handsome each day with the same eyes as mine. No matter what girl he'll meet, I know someday he'll find the right girl who is kind, loving, and carefree. As long as she can do the same as I have loved him. I wish I could see Adrien building his own happiness and I hope the girl of his dreams can make him happy too. And I hope Gabriel can see the happiness too as long as he can give up on his madness and not force Adrien to obey every command of his" Emilie said in her recording.

Marinette smiled seeing her, "If only I met her"

"Juleka did say she wished to be a mortician. She does know a bit about seance" Adrien said.

"Science?" Marinette raised a brow.

"Seance. It's like contacting spirits or the dead" Adrien said.

"Oh, I see" Marinette replied.

"Marinette, the reason I loved you was because it took me this long to see it. Even if I was too oblivious and dumb to not see how hard you tried to tell me, causing you to suffer so much pain and clumsiness to backfire it" Adrien said.

"Oh, Adrien. You're such an understanding guy" Marinette held his hands, "Sure I did love you first because of your handsome face but I got to know you as a person" Marinette said.

"And that's what my mother would have wanted for me to have someone to care for me. My father only wanted to force me to marry Kagami so their companies combined and I would never throw away my happiness for him. My mother wanted me to continue to be happy with the life I'm building on my own without commands or orders from anyone" Adrien explained his reason.

"I understand. She would have been so proud of you being one of Paris's heroes" Marinette said.

"Heh, that's another reason why I named my alter ego after a bedtime story she read me as a kid" Adrien chuckled.

"Heh, seems like she inspired you" Marinette chuckled too.

"And to honor that bedtime story character for her," Adrien said.

"Is that why you make so much cat puns to impress Ladybug?" Marinette asked.

"Yes, it was," Adrien said.

"That makes a lot more sense now," Marinette said.

"And it explains why you could tell Lila was lying about Ladybug because you are here," Adrien said.

"Yes, but made a nemesis out of her," Marinette said.

"Technically you did but you wanted to save me from a deceiver which we didn't know this whole time. I still don't understand how she lied and was not caught in fake identity crime when her fake name did not exist in birth records or anything" Adrien said.

"Well, I still wonder too," Marinette said, looking at the horizon.

"I just hope she gets her senses right because not only she betrayed Paris but she also betrayed her family she never had along with ancestors who would be so disappointed in the afterlife to see a descendant becoming something far worse. If she was abandoned by her real parents, maybe they are the cause of her pain" Adrien said, knowing what it's like to feel mistreated or abandoned by a parent.

"Possibly" Marinette shrugged.

"As much as I want to help her see past her pathological lies the same way I want Chloe to see past her selfish behavior, I just don't like when we have to fight fire with fire, we all get burned. When someone hits you back, you hit back hard. So hard, we all get hurt" Adrien explained why every good and bad person gets hurt in different ways.

"Yes, Both mentally and physically," Marinette said.

During the next few days In the asylum, Cerise received the news that since Monarch had died, several miraculous heroes had returned during the last days to fight crimes. And the news was out that Gabriel supposedly died in the battle to cover up the story with a statue of him getting ready to be placed.

"So now the butterfly brooch is gone forever?" Cerise saw the news.

"Why am I not surprised?" She was brought to her cell.

"I would be surprised if you stopped being a liar for once, missy!" The security guard said.

"Hmph!" Cerise scowled and sat down.

"And you have two visitors. Better behave or you will get sentenced to the full-time punishments" The other security guard said.

"Who?" Cerise asked.

"That would be us," Marinette said.

"Surprised to see us, Lila? Or should I say, Cerise?" Adrien said.

"So this is what you look like? The real you? No wonder Princess Justice was so vengeful to see how you deceived everyone. Especially lying and not getting caught as fake identity fraud from any identification records" Marinette said.

"Those fools didn't even bother to check when I came to Paris," Cerise said.

"And that's a reason why fake identities are a punishment crime. Unless you want to convince them you're not an alien from Area 51" Adrien said sarcastically.

"Now where's the fun in that? Switching identity made me get away with any crime" Cerise said.

"Except there's no such thing as having multiple names. Just one for a real birth name" Adrien said.

"And your real birth name is Cerise. If your ancestors were here, they would feel betrayed" Marinette said.

"Or better yet, maybe you're like your ancient ancestor who lied about Mt. Vesuvius being extinct until it was a lie and killed millions of people to be statues of Pompeii" Adrien threatened her.

"Are you threatening me?" Cerise asked.

"You're one to talk. You threatened Marinette in the bathroom and you like threatening people who can see through your lies and yet you don't like when others threaten you" Adrien points out his facts.

"When you fight fire with fire, everyone gets burned, including you and us, Cerise. Instead of being honest with yourself, you're still not gonna change at all. Your mind and soul are stuck in a void that can't get out" Marinette said, talking about Cerise's unhealthy mentality of becoming a pathological liar that can't redeem herself.

"We did not come here to argue, we just want the truth," Adrien said.

"And no more lies," Marinette said crossly.

"You think you never lied in your life?" Cerise laughed insanely.

"Only for safety reasons," Marinette said.

"Everyone lies in unique differences in life. You just lie to gain attention or avoid trouble" Adrien said.

"And you wanted me out of the picture because everything I do in life is not by fake or popularity," Marinette said.

"Yes, because you were first to see through my lies," Cerise said.

"Removing someone out of the picture doesn't prove you're the best, Cerise. You can change on the outside all the time but you can't change on the inside. Marinette is not just something to take away, she has a heart of kindness. You're nothing like her and being her is not easy. Her life is not always easy" Adrien explained why being someone doesn't mean everyone will love someone to be replaced.

"You think I should care? In my whole life, I never had a real family or real friends! You think being a nobody is easy to gain attention?!" Cerise yelled.

"Of course not! Being popular isn't everything and attention isn't always fun" Marinette said.

"My whole life I hated being a rich boy. I never liked being a model. When you're way too famous, you get stalked, harassed, sexually harassed, and definitely lied to on social media" Adrien said.

"Like that Kagami, you were forced to date?" Cerise replied.

"Yes, but she never wanted to carry the legacy for her mother. How would you feel if you were forced to date a boy you don't love but still use him for fame, what if he tried to force you to have sex with him?" Adrien asked.

"I wouldn't like that," Cerise said.

"Exactly. Especially how I was forced to model with you and I felt like I wanna die" Adrien glared at her, reminding her of the times she constantly put her hands all over him in modeling which is called harassment to the touch.

"Aw, is that so?" Cerise smirked.

But Adrien chuckled as he brought Felix in Adrien disguise and he walked in, "Except one time, I was not on the train the day after Shadow Moth became Monarch" Adrien explained.

"WHAT?!" Cerise gasped.

"I may have fooled everyone but I did him a favor so he wouldn't be with you" Felix combs back to his regular style.

"Except you tricked me, lied to me, and still committed impersonation" Adrien added to him.

"Fair point. But yes, that was me the day I sent the video to his friends about nasty things out of jealousy and stupidly got his friends akumatized. Kinda the same way you sent that selfie photo of you and him to all the girls until Kagami got akumatized into Oni Chan to go after you. We are both the same but I'm the opposite of you, Lie-La" Felix smirked at giving facts about how similar they both are.

"Hmph! Unlike you, I made Marinette's friends my unwilling pawns through lies" Cerise said.

"Because of you, you ruined that school's reputation!" Marinette added.

"And caused a lot of damage to everybody's dreams and happiness. I know a liar when I see one. I may look like an identical twin to Adrien but I'm not everything like him. When you disguise yourself as fake girls, you're still the same con-liar you are. Unlike you, I don't need a wig or eye color contacts because everyone sees that he and I are twins, just not the same personality" Felix said.

"Although we both have the same sound of our voices" Adrien added.

"Yes, but as Ladybug pointed out, the real you is never pushy," Felix said.

"And punched you for that" Adrien snickered.

"Yes, well, I deserved that" Felix rolled his eyes that he did not need to remember getting punched.

"I hope you enjoy your stay in the asylum Cerise, because I hope we two never meet again, but first the truth!" Marinette walks up to Cerise.

"Heh, your memory of me will still haunt you forever, Dupain Cheng. Do you want the truth? Very well. I was jealous that you had everything but when you saw through my lies, I wanted to make your life miserable the same way Chloe wanted to do the same to you. I did take every spot you were in, so you had nothing" Cerise confessed.

"So that's it? You just wanted my life?!" Marinette exclaimed in anger.

"Yes, so I don't feel like a nobody! I never had loving parents or friends as a kid! Just like I was tormented at the orphanage for years until I had to escape! I wanted everyone to feel exactly as I have suffered! Why do you think I manipulated Chloe when she was aware that I was a liar? Because Chloe only trusts bad people who want the same thing but she's too dumb to be played as a pawn" Cerise laughed insanely.

"You were also a pawn for Monarch, Cerise. He doesn't care what you feel or go through. If Princess Justice was a better successor which she was, Volpina would not be his favorite anymore. He would believe Volpina, Chameleon, and Hoaxer were just useless. Unlike you, Princess Justice went against him for the first time in history because she had a sense of justice and hatred towards injustice which includes you and him" Marinette said.

"But he was foolish to akumatize me into Hoaxer. I wanted revenge on him for firing me. I managed to get his secrets" Cerise smirked.

"Technically I did too," Felix said.

"Either way, one way or another the public will know his past," Cerise said.

"Not as long as I keep my mouth shut. But no one will believe a liar like you" Felix said.

"Hmph, you may have fooled me on that train, but you won't fool me again," Cerise said.

"And I'll make sure you don't fool Kagami again. You manipulated her instability twice. Unlike you, I spared Marinette that night because hurting her would only hurt Adrien more. You hurt Marinette a lot to have Adrien angry and hurt to see how much of a real monster you are. You think hurting Marinette will make Adrien like you?" Felix made a deadly stare look to immobilize her.

"No, I was in fact planning to break him too," Cerise said.

"You're even more screw loose than I thought. When you have a lot of consequences, you don't feel ashamed at all. Unlike you, I indeed felt ashamed of myself for committing genocide because I had to see the errors of my outcome or I would have become like you or my uncle" Felix glared angrily.

"It's only a matter of time until I get out and get my revenge on you Marinette!" Cerise bangs the door.

"Good luck with that, until you are all old and stiff" Marinette sneered and left with the boys.

Cerise screamed in anger at the top of her lungs.
