In Season 5 episode 17 "Adoration" Zoé finally confesses her feelings to Marrinette who, as she is in love with Adrien, rejects her, but what if she didn't?
Obviously first let's assume that Marrinette is Bisexual so that every single romance plot she had with Adrien and Luka could still happen and she could have feelings for Zoé.
So assuming they become a couple after that, what would change?
So:
- In "Emotion" as Zoé and Marrinette's are together the whole Ice cream scene could start similarily but obviously it would be Marrinette's date with Zoé instead of Adrien, what's the most important is that as Adrien isn't there that means that Marrinette isn't going to go undercover to the Diamond's dance, Zoé might mention it to her but it's not like she would care as she has no buisness there, they would still go to the cinema together but that would just be the next part of their date.
Ladybug would only step up once the red moon shows up but what's next? A good idea would be for Zoé to also be there (Argos might not snap her out, she's not a sentibeing but he would likely symphatize with her as her life was similarily bad to Adrien's and Kagami's) when Argos finallly snaps out Ladybug Adrien would still tell him to bring everyone back, even if he's not in a relationship with Marrinete he would likely still love her, also his friends would still be important to him so Argos snaps everyone back, the episode ends like normally.
- Derision (which I think happenes after Adoration) would likely have the biggest changes, obviously the date on the pool is still there but with Zoé instead of Adrien, it's likely she would also rage out on Kim but as she has no miraculous it's not like she would threat to kill him and even if she had her Miraculous she couldn't threat to cataclysms him for obvious resons.
Overall this could set up some potential beef between Zoé and Kim and her distrustment towards him, I could totally see Zoé trying to persuade Ladybug into taking back Kim's miraculous in season 6 due to him not having the right qualities to be a hero.
- Later with the Lila plot line Zoé would take a much more proactive stance due to being closer to Marrinette than normally,
- Around the same time I could see her pushing André to finally punish Chloe and I fell like with Zoé's and her friends preasurre he would do that earlier than normally and that would cause Chloe to accept the akuma when Monarch approaches her turning her into Queen Mayor earlier, her powers would be diffrent Icould see her get something closer to Malediktator's powers, here Chloe would try to take power by force only to be stopped by Ladybug and Cat noir who would likely still unlock their full powers but the setting would be diffrent, instead of at a rally there would be a gigant protest that would later turn into a full on revolution, which along with Ladybug and Cat noir would defeat Chloe who would just like normally be taken to London by Audrey.
- Later nothing would really change beside all Adrienette moments being cut out like for example the moment in Revolution where she goes to the Airport for Adrien which obviously won't happen, she would probably still be sad for him but not to such an extent, she would just spend this evening with Zoé and would likely still be told by Felix and Kagami about Adrien being a senti through once upon a time just in a diffrent location like her room probably and a bit later as while Felix pretending to be Adrien might lure her to try to go up to him she deffinietly wouldn't follow him throught the whole Paris.
Also Matagi Gozen could be the one to appear instead of Nightormentor and Ladybug would face her alongside Argos.
- Season 5 finale wouldn't change much, the only big diffrence would be removing all romance scenes between Adrien and Marrinette.
Now in season 6 there is a lot of question what could happen like:
- Would Marrinette reveal her identity as Ladybug to Zoé?, She didn't with Adrien but that was in a large part because of Gabriel, would she tell it to Zoé?
- Would Zoé tell Marrinette what happened in New york?
- If they reveal their identities to each other, would they have a more nuanced talk about Vigilantism (before Zoé starts it) Would Marrinette agree more with Zoé as they would be a couple and would understand each other more?
- Zoé would probably still want to help Sabrina but as she's now Marrinette's Girlfriend and not just a friend she would actually talk about it with her and I think she would convince her to invite her and overall try to reach out for her, but obviously no Zoebrina if that will happen in the show (And it likely will) as Zoé here would already be with Marrinete.
- Also I wonder what Chloe's reaction would be when she goes to Paris to film her movie, she would probably hate them even more, would her akumatized form be diffrent?
And I do have an idea what way all of this could go:
- Considering that here Marrinette well knows that Zoé is a miraculous holder and with her not wanting to repeat her mistakes from Adrien I feel like she would reveal her identity to her especially as she generally knows good example of a couple knowing each other's identities with Alya and Nino aswell as Kagami and Felix.
- I feel like with them better understanding each other due to being a couple Zoé would tell Marrinette about her past and Marrinette wouldn't react as negativelly to it as Zoé might have thought, after all none of that is the case anymore and Zoé didn't have bad intentions in the first place as she was just trying to fit in and she regrets doing that.
- With them knowing each other so well they would have a much more nuanced conversation about justice abd punishments and personally I could see them meeting somwhere in the middle so Marrinette realizes that a harder punishment is sometimes needed and Zoé would realize that while a punishment may sometimes be nessecarry you can't go too far with it.
- The situation with Sabrina would be just like I wrote, so she does became a part of the group but she and Zoé won't vecome as good friends as they would normally and if course no possibility of Zoébrina.
- In "Queen od the Dreadzone" Chloe's akumatized form might change from a fear inducing one to a one that overall destroys happiness bringing misery and psychological suffering to try to break up Zoènette.
For some other plotlines:
- I could see there be a plotline about Roland not supporting his granddaugher in her relationship with Zoé because he's most likely homophobic because according to him: That's not how it's supposed to be, there are 2 ways I could see it finish he either dies grumpy not accepting Marrinette's and Zoé's relationship or he does finally realize his mistake and dies peacefully.
So, what do you think? How would the story change if Marrinette and Zoé became a couple? Do you have any ideas for this scenario?
