It would be funny if Andre got evilized in a future episode and Ladybug and Catnoir hear him ask them whether it’s possible for him to right his wrongs about Chloe and for Chloe to come back. Ladybug is angry at Andre upon hearing this. Catnoir is like, “So you want to become a better father to Chloe? You felt guilty about not being a good father. Is that why you want Chloe to come back? Is that why you got evilized?”
Catnoir is angry when Andre reveals he was evilized due to distress about his directorial prospects not going to plan, and that Andre wanted Chloe to come back to use her social media influence to boost his career, not so he can become a better father.
Then cracks form in Catnoir and Ladybug’s relationship when Catnoir realised that Ladybug was angry at Andre because she didn’t want Chloe to come back, not because Andre is such a bad father.
I was supposed to post this but accidentally saved it to my drafts 😭. Anways
The concept of Andre getting akumatized because he realized he's a terrible father is a really interesting concept!
In canon, and despite being rather negligent, Andre does try to make his daughters happy and seems sincere when he does so. When it comes to Chloe, he has a routine of gifting her expensive things when she's upset, not realizing she needs someone to confide in. Someone to comfort her instead of buying off her emotions. This changes with Zoe as it's a fresh start. He chooses to be different now that he reaped what he sowed.
How he comes to this realization could be up to anyone, but for the sake of this scenario, let's say Chloe had a minor (major) freakout (assuming she's in paris at this moment) about how different Andre was treating Zoe over her. Thus, he reflects over his past actions and acknowledges how little he knows about his birth daughter. Zoe wants to support her dad and offers a few ideas on how to approach the situation. Only for Andre to repeat his mistake by trying to bribe her, which doesn't work this time as Chloe has had enough. In despair, he is akumatized but not out for revenge but deep sorrow.
Hence, Ladybug and Chat Noir talking to akumatized Andre, learning about why he was akumatized and such. Instead of Ladybug being the one to reassure him, Chat Noir being to one to break Andre out of his akumatized state. The reason why is very obvious. Adrien wishes his dad made an effort. He knows more about this than anyone. (Plus, we need more Adrien-focused episodes/fics)
Ladybug really is there for support, but she doesn't mind.
While I don't think he wants to use Chloe, I doubt he would want his reputation to plummet from being a bad dad. However, what could happen is he misspeaks about his intentions, making it sound like all he cares about is reputation. Which causes the sympathy in Noir to decrease. He'd say something about stepping up emotionally and treating his daughters as equal before leaving, Ladybug says a few short words of encouragement to Andre before following Noir to ask what's up.
To focus on the Marinette aspect of this, I don't think she'll proceed with much resentment towards Chloe. Especially knowing the dynamics at play better, Marinette grew up with two loving parents, they're important to her, and she knows how much it would sting to not have that support. After this, I don't know why Marinette would be able to hate Chloe.
What happens next is up to you, and I'm sorry to have strayed a few things away from your idea, but I just wanted to bring in the Adrien angst that the show should expand on. Plus, the Chloe and Adrien friendship dynamic we've missed out on. Those two are really one of the few people who can understand each other and it's a shame how things ended.
Anyway, I loved the concept, Anon! If you have anything you want to add, feel free to!! I am always down to hear more ideas. ^^
