What would you think if Chloe and Audrey heard rumours about the way they were going to be portrayed in Astruc’s new movie, so they went back to Paris in an unsuccessful attempt to stop the movie from being completed? Then an evilized villain (maybe a wishmaker-like villain or maybe even a villain that's unrelated to the butterfly miraculous) caused Chloe and Zoe to switch bodies somehow, and nobody fully understands what's going on, so Zoe (in Chloe's body) is taken by Audrey back to New York, despite Zoe desperately trying to explain things.
But Chloe enters a fugue state (heavily due to trauma caused by the neglect of her parents) and genuinely thinks she's Zoe, and is even able to recall many of the things Zoe did due to being in Zoe's body. The class thinks “Zoe's” change in behavior is due to the psychological effects of method acting, since “Zoe” is playing Chloe in Astruc's new movie, but they gradually convince “Zoe” to let them help her relearn how to be “herself” again.
Zoe is not able to gain access to Chloe's memories while in Chloe's body, because unlike Chloe, Zoe knows she's in the wrong body. In New York, Zoe is trying to get back to Paris, but when she gets there, “Zoe” thinks she’s there to try to hurt Marinette. Eventually, after listening to “Chloe”, Marinette starts to suspect that “Chloe” might be telling the truth, so she decides that she must test “Chloe” and “Zoe”. She fakes being in danger to see how they react. “Zoe” reacts slightly faster than “Chloe”, so Marinette comes to the conclusion that “Chloe” is lying and that “Chloe” has an evil and manipulative plan. Marinette thinks that “Chloe” must have picked up a few tricks from Lila, because she thinks no version of Chloe could possibly react faster than Zoe when it comes to protecting her. So Audrey takes “Zoe” back to New York again to “correct” her after “Zoe” fails to convince anyone of the truth.
10 years later, “Zoe” gets seriously injured after fighting a villain when Ladybug isn’t around, which causes “Zoe” to not have long to live. Then Ladybug accidentally stumbles upon the truth about “Zoe” while trying to help “Zoe” using magical powers. Ladybug decides that the moral thing to do is to switch Chloe and Zoe back to their original bodies. Once Zoe gets her body back, she blames Chloe for her impending death and for leaving her with 10 years of loneliness, while Chloe got off scot-free.
At first, when Chloe gets her body back, she still thinks she's Zoe, but she eventually figures out the truth by reading the journals "Chloe" kept over the 10 years of time. When Lila gets defeated, Zoe steals the Butterfly Miraculous to get her hands on Ladybug and Catnoir’s miraculouses, hoping to “make things right”. Zoe gets defeated by the heroes (including Chloe, who has gotten her memories back) and Ladybug manages to cure Zoe’s injuries by injecting her with the cure.
At first Zoe seems like she's about to surrender due to being grateful for Ladybug's help, but it turns out to be a ruse. Zoe thinks she's gone too far and that it's too late to turn back. Zoe snatches the ladybug miraculous and gets away from Marinette. Zoe hesitates to make the wish when she realizes that she'd need to sacrifice the lives of Marinette and Alya to make the wish a reality, and that they wouldn't return in the new world she wants to make. Just as Zoe is about to make the wish, Chloe arrives and attempts to reason with her. Chloe manages to talk Zoe out of making the wish and even gets the cat miraculous and the ladybug miraculous back. The other heroes arrive to find that Zoe has gotten away with the butterfly miraculous. Chloe is fully accepted into the hero group after this.
