Also does it have a fic

Jaune Jack is an au that takes place after Chloé leaves in Season 5

Audrey takes Chloé out of Paris and sends her to NYC and is... low-key hiding her. Like took all her social media access and is using the AI holograms that Gabriel had used for the Alliance Rings to fake the idea of her living it up in London and using the content to subtly cause problems in Paris(like in the Climactiqueen episode where the contest pressure got Aurore Akumatized, but more on purpose and encouraging of her spiral and Akumatization).

Buzzen (Chloe calls them Buzz affectionately) the Wasp Kwami of Retaliation!

Object would be an earring cuff which Chloe wears on her left ear. Her power is Recompense (Buzz calls it "right back at ya!"). Basically when she activates her power she stores the most recent attack that she's taken and can store it for later use.

Theoretical Examples: Let's say Pixelator hit Chloe and turned her leg into pixels like he did with Marinette. She could use her power to store that effect and use it on him later. Or if Anansi hit her and sent her flying, she could use it to knock Anansi off balance with the same strike. Or if Stormy Weather covered her arm in ice it can replicate the ice as well. It's a very niche power that needs be used smartly, she only gets one use before detransforming. She can also channel the power into her weapon.

It's weapon isn't an esoteric music instrument or a toy something. It's a knife that can extend into a spear. It has a limited extend range though, not like Cat Noir's infinite staff. Just the in-between of knife and spear range.

She names herself "Jaune Jack". Jaune being French for yellow and Jack from Jacket. So she named herself Yellowjacket but with some flair.

Buzzen was created at the same time as Pollen, essentially twins so they look alike but Buzzen has more black in their design than Pollen. Buzzen was deemed too much trouble to keep around at the Order so they were sent away with no intention of returning. Pollen was told that Buzzen left of their own accord which they have doubts about. Buzzen misses his twin so when he was awakened by someone who had trace amounts of Pollen's magic overjoyed would be an understatement. Then rightfully pissed at Ladybug once told the full story.

Marinette: Wait. Why is Chloé there??

Luka: Yeah? I'm staying at her place in New York while dad's doing the Europe leg of his tour.

Marinette: WHAT. BUT SHE'S A BULLY!!

Luka: Felix pretended to be Adrien and left horrible voice messages for everyone when we first found out about him. Now he's dating Kagami. Chloé also calmed down.

Marinette: but but but she exposed everyone's identities!

Luka: and that didn't stop Ladybug from giving them back their miraculouses..?

He just like doesn't get the double standard cause he's also trusting of people.

See I'm just imagining him like. Not explaining?

And it's it's it's-

It's half that he wants to let Chloé explain for herself when she's ready(if she ever wants to talk to the rest of the class again anyway), and partly Identity Shenanigans(this is Canon-compliant on who knows who so explaining Miraculous Shenanigans to supposed Civilians is a no) and partly that Marinette kinda did the same thing with Felix to not explain why he did what he did and the whole Sentimonster thing and the Gabriel-being-Monarch thing she just went "Yeah Felix is chill now".

If Marinette got curious about the full extent of 'how much was genuinely chloe, and how much was other people using her" Alix could technically create a "highlight" reel that is Chloe's fall for her via Burrow.

Honestly it's like.

It's so hard to really tear apart what was Chloé and what was the shitty people around her?

Blueshift:"Can I talk to you real quick?"

Miss Blink:"Of course."

Blueshift:"It's personal, not professional."

Gwendolyn Skipp:"I'll help if I can."

Azure:"...I'm thinking about coming out to my parents. They accepted me for being enby, and I think they'll accept my powers. But..."

Skipp:"If it goes poorly, call me. Or just run to me, that'll probably be faster. From what you've told me about them, they seem like they won't have any issues with your speed, but if the worst comes to pass I'll have your back."

She gives him a feigned bored look and says, "Viperion." as a faux greeting and then walks past him to sit next to Fang on the floor. Jagged just says they'll be back in a couple hours and tells Luka they should get going. Luka is incredibly confused.

Honstly I can see Felix collecting a lot of evidence that Chloe is a Senti but all of it being circumstantial

Like yeah Chloe has more magic than average but nothing unprecedented

Is Jason making all those hospital visits because of the Peacock or this thing that runs in his family?

Did she never go to the hospital because of being a Senti or because Andre never bothered to take her?

Stuff like that

Yeah exactly!

Like it's just a bunch of circumstantial things.

Magic can fluctuate wildly in someone's base talent/ability. And though genetics is a factor it doesn't have to be(relatives are often of similar Magic prowess, but you can have a powerful person make a weak child and vice versa)

Like even if Jason's Magic is damaged, there's other causes than a broken Miraculous. You could try Channelling other Gods. Push beyond your limits. Run into a particularly ornery Osmosian. Etc.

Chloé's lack of doctor visits could just be because Andre just. Never took her for things that were routine, and she luckily never /needed/ one, often getting better by slamming otc meds.

It's all circumstantial and could lean one way or the other.
