In Marinette's room, Ladybug contemplates the Cat Miraculous, surrounded by the kwamis.

Ladybug: What's gotten into him? I didn't do anything.

Luka: I'm sure there's a reason behind it.

Plagg: Didn't do anything? Well yeah, you did! You've been neglecting a very classy piece of camembert on your plate for too long! And as a result, it got runny and moldy!

Ladybug: What? Cat Noir never gave me any camembert.

Plagg: Of course not, Cat Noir is the camembert! For a while now, you've been neglecting this camembert— I mean Cat Noir and going on adventures with all other cheeses!

Ladybug: But he should be happy about it, it gives him more time off.

Plagg: Cat Noir doesn't wanna have time off, Ladybug! He is in love with you! And your persistent calling on other heroes has broken his heart.

Ladybug: I'm not in love with him. I made it pretty clear to him, and I'm sorry if Cat Noir is hurt, but I'm doing my best as a guardian.

Plagg: (sighs) I know. Just... give me the Miraculous. I'll give it back to him, cheer him up, we'll chow down on some grilled Mimolette sandwiches, and everything will go back to normal.

Ladybug: It's useless. The problem is that Cat Noir is in love with me. And since I can't do anything about that, I'll keep on breaking his heart over and over again. Maybe Cat Noir is right. We should split. *The kwamis gasp. *

Plagg: Woah! Not so fast! May I remind you that Cat Noir is a very competent superhero and that your powers complement each other?

Ladybug: I know I can't do it without a Cat Noir... So, I'll just have to choose another one, who won't be in love with me! *Luka looked sad at Ladybug. In Adrien's room, he sadly throws all photos of Ladybug from his trophy and cheeses into the trash, then does the same to the sock puppet Plagg. *

In Marinette's room, Ladybug looked at the ring and Plagg.

Plagg: Another Cat Noir? What do you mean by another Cat Noir?

Ladybug: I'm going to choose a new Cat Noir myself. One who won't be in love with me. And since I'll know who he is, I can call on him whenever I need him. (She jumps to the balcony.)

Plagg: Woah, woah, woah! You mean you'll know who he is? You'll know his secret identity?

Ladybug: You're right! I can't do that! *She looked over at Luka. * Think it's for the best?

Luka: I'm not sure if it is. And it's only fair when I know.

Plagg: Wait, you know his identity? When did this happen?

Luka: When we were fighting Wishmaker, he hit Cat Noir, which revealed his identity. I swore Ladybug I wouldn't say who he is.

Ladybug: And if I know who Cat Noir is and Shadow Moth akumatizes me, he'll know where to find Cat Noir and he'll capture both our Miraculous! He'll merge them and make his wish come true, and then the whole world will turn into whatever he wants! *She envisions Shadow Moth with the two Miraculouses surrounding the globe and saying "Finally!". *

Plagg: See? You can't do that, so come on, give me back the Miraculous. I'll just tell him to erase you from his heart, and everything will be fine.

Ladybug: You think he's capable of that?

Plagg: I sure hope so. *He took the ring and flew back home. *

Luka: Think Plagg can convince him?

Ladybug: I hope so. If not, I'll have to find a replacement. Somehow. *When nighttime came, inside Adrien's room, he was in bed, deleting photos of Ladybug from his phone. He leaves one, puts the phone away, and turns away. *

Adrien: I'm sorry if I wasn't much help, Ladybug. *He keeps deleting the pictures of her. *

The next day, Marinette tries to figure out what to do.

Marinette: Not sure if this will work. What do you think? *The other Kwamis looked at her plan and they were unsure. *

Tikki: I'm not sure it'll work, Marinette.

Marinette: You're right. You better start thinking of some replacement options.

Plagg: And yet, my holder loves her.

Tikki: But my holder loves someone else.

Plagg: Sugar cube! I know how to fix this and get them back together! But I'm gonna need your help.

Tikki: With what? *He whispers something to her. Inside Adrien's room, Nathalie walks in using a special device. *

Nathalie: (coughs) Adrien, you're late for breakfa— *She sees him turned to a side in bed and gasps. * Adrien? Are you okay?

Adrien: I'm fine, Nathalie. I just don't feel like going to school. *He covers his head with the blanket. Inside Gabriel's atelier, Nathalie told Gabriel about not wanting to go to school. *

Gabriel: When is his next photoshoot?

Nathalie: In three days.

Gabriel: He will feel better by then. He's an Agreste.

In Marinette's room, Marinette works on homework as Plagg pushes Tikki up to Marinette.

Tikki: But I can't lie to Marinette!

Plagg: Who said anything about lying? I'm just asking you to smile and nod! (He flies over to a growling Marinette and clears his throat.) My dear guardian, you cannot continue keeping both the Miraculous of destruction and creation under the same roof. If Shadow Moth ever found that out and came here...

Marinette: Still no thought about a replacement yet. I'm sure something will hit me eventually. *The vision of Shadow Moth reappears saying "Finally!" yet again. Marinette pushes it up. * This could be harder than I thought.

Plagg: Because you can't know his identity, right?

Marinette: What? It's not that easy, you already know what would happen if we both find out our identities.

Plagg: Yeah, I do. So, dry your eyes! We've found the solution! Tikki's the one who reminded me of it.

Marinette: Really? *She looks at Tikki in surprise. Tikki nods nervously. *

Plagg: My owner is indeed fantastic, but there is one other boy. Master Fu hesitated between the two of them when he was choosing Cat Noir, and Tikki and I liked him even better. *Tikki nods again. * He'd make a perfect Cat Noir! And more importantly, he's not in love with you, and I mean not at all!

Marinette: How can you be sure of that?

Plagg: Because... it's a kwami power! *Tikki continues nodding awkwardly nodding. * And, since I can go and present the Miraculous to him myself, you'll never know who he is! That way, you'll have a new Cat Noir, who's not in love with you at all and everything will be perfect!

Marinette: (looking at the Miraculous) But... isn't it kind of risky to leave you on your outside without a holder with your own Miraculous? What if Shadow Moth would capture you? *The vision reappears, but Plagg shoves it up before it finishes. *

Plagg: Shadow Moth doesn't even know that Cat Noir has given his Miraculous back!

Marinette: We have to agree that this new Cat Noir would be up to the challenge, right? We're spending time together, so I have to be able to get along with him. He'll have to be nice, generous—

Plagg: Hang on, I'm talking about a top-shelf Cat Noir here. Brave but calm, and rational too! As strong as he is intelligent, thoughtful, and trustworthy. I promise you, take the time to get to know him and you'll see he's the Cat Noir of your dreams!

Marinette: (skeptically) Are you trying to pull one over on me, Plagg?

Plagg: Oh, Sugar cube, tell her! She can trust me, can't she? *Tikki nods, failing to be genuine. Marinette looks at her and back at the ring. *

Marinette: Okay then.

Plagg: (grabs the ring as the Kwamis exclaims) I promise you won't regret it! *Marinette looks at Tikki one last time, who continues to nod. *

Marinette: Should I start regretting?

Tikki: For once, no. You'll probably think this will be a good thing.

Marinette: Okay. *In Adrien's room, Adrien is on the couch, playing a videogame, or rather running into a brick wall as the playable character. Plagg knocks on the window. *

Adrien: Plagg? *He opens the window. * If you're here for your cheese, it's over there.

Plagg: Not at all! I've got a great plan to get us back to *He gasps. * No! My favorite old honey tomme cheese! Mushed into fresh goat cheese... well, we'll deal with that later. I'm just gonna blame this on your recent psychological state. Listen, I have Ladybug believing that I found a perfect new holder for Cat Noir. And this new holder is you! *He looks at the screen and sees the character constantly running into a wall. He flies in front of Adrien. * Come on! What do you say to your good old Kwami buddy who you thought you'd never see again? *He flings the ring at Adrien, whose depressed expression doesn't change. * Hey, you! Enough with the talking gloomy act! You and me, just like before!

Adrien: I can't be just like before, Plagg. If I become Cat Noir again, Ladybug will just end up rejecting me, over and over. *Plagg looks at the rubbish bin and back at Adrien. *

Plagg: I get it. It's hard to be thrown out with the old cheese rinds. But I'm not talking about being the Cat Noir you used to be! *He pulls in a drawing of Cat Noir in a superhero cape and places the ring in Adrien's hands. * You're gonna be the new Cat Noir! Wait until you see how brilliant this is! After all the time I've spent with Ladybug, I know exactly what she's looking for! So, you and I are gonna whip up a tailor-made Cat Noir! So perfect that believe me, she'll never forget to call on you for help again!

Adrien: (looking down at the ring) But as soon as I transform into Cat Noir, she'll know it's me.

Plagg: (drawing over the board) Nope! Because when your personality changes, your costume changes too! Up until now, whenever you transform into Cat Noir, you don't think about it, it is natural. And what came out was this Cat Noir. *He crosses out the picture of a goofy Cat Noir. * Not at all what Ladybug wants! But if you focus hard, you can be a completely different Cat Noir!

Adrien: You think so?

Plagg: Of course! Concentrate. *Adrien puts the ring on, and Plagg giggles. Adrien starts concentrating. * Alright, you're like a little ball of fresh curd, that doesn't know yet, that it can be something more than a camembert! But if you think hard about what you're doing, if you age your crust and choose the right fermentation, you can be any cheese you want.

Adrien: Plagg, claws out! *He transforms into Cat Noir. *

Cat Noir: (groans) Claws in.

Plagg: Okay... we've got some work to do. *Sometime later in the same room, Adrien with a Cat mask practices arrival poses while Plagg in a Ladybug mask denies his first attempts and approves of the third, calmer one. Adrien is deciding between two masks for his new suit, and Plagg places one on a sketch. *

Plagg: (writing on a whiteboard) Serious Cat? A little too direct. Silky Kitten? Hmmm.. too cutzy. Night Whiskers?

Adrien: That's pretty paw-sitive, isn't it?

Plagg: (strictly) What did we say about cat puns?

Adrien: (sighs) No more cat puns under any circumstances.

Plagg: You know how to be serious, like when you're with your father and Nathalie. Just be like that! *He straightens Adrien up. * Mm-hmm. Perfect. And I guarantee that Ladybug will not be able to do it without you. *He and Adrien come closer to the whiteboard, and time passes quickly. * Kitty-Kitty.. Cat of the Night... Citizen Cat... Obscure Kitty... Super Cat... Black Kitty... Feline Kitty... Cat Man... Adrien, I think we finally got it.

Adrien: Plagg, claws out! *He transforms in his room. *
