How easy it would have been to not divide the fandom.
Chloé Bourgeois. Redeemable? Not? Failed hero? Creator's punching bag? Brat? Bully? A once vibrant character pounded into 2 dimensions?
There are a lot of takes and many of them passionate about her. I'm not here to tell you it should have bene X or Y(right now) I'm here to say, everything could have been the same, save for a single simple one or two second addition, and most of the divisions would have disappeared.
What is this miracle? Well, it would take place in any episode where Bunnix is involved already. There are many ways to do it in such an episode. Be it a future time visited in Evolution, something occurring behind Bunnix as she pops in one of her portals, or even just an image or sound from one of the many portals in the burrow.
It could take many forms: Someone who looks like an Older Queen Bee glimpsed in the background, if you wish visual, or an auditory clip of an older sounding Chloe saying 'Buzz on' or 'Look out Ladybug!' or even just 'Thank you, Ladybug'. It doesn't need to be paid any attention in the show, it just... happens.
This plants the notion that at some nebulous point in the future(which the creators don't actually ever need to get to) Chloé will be on good terms with Ladybug. It admits, and even promises the idea of *change* Chloe does not have to be who she currently is.
What does this do? It shifts the entire emotional engagement of her actions. Instead of the boring-bully motif of S4/5, instead of some people angry and others rolling their eyes at the more ridiculous spiral of S5, and instead of people accusing/defending the creator of hating and writing a character simply for abuse.
They can be frustrated with Chloe herself. They will *know* she can improve. They can groan when she fails, they can realize she is failing herself as she hurts others. The negative feelings are shifted towards falling short of potential. It becomes 'look what you are doing to yourself, and others. I know you can be better!'
And if the creator really is a grumpy soul who hates her? The show never actually needs to cash in on the 'someday' they get all the emotional investment and engagement without having to deliver. Because 'someday can always be 'not today'.
