(So both Felix and Zoe are present from the start of the series)
-Chloé is still very much the same, but treats Zoé like she did in the season 4 opening (minus the whole tour in Sole Crusher)
-Audrey isnt present yet. And without Marinette reaching out to Zoe, Zoe just does what she has been doing (playing a role)
-Felix and Amelie move into the agreste mansion. Much to Gabriel's disdain. But Emilie was always protective of her family, and Gabriel's hermit nature made him pretty cold to them.
-Amelie noticed how Adrien was being ignored by his father, and encouraged Felix to help out Adrien.
-Felix is still very much the sneaky little gremlin he always is, but in this au two things (1. He and Adrien are still very close. 2. Felix does not know he is a sentimonster like that it was all but said in Gabriel Agreste.) Felix is still suspicious of Gabriel.
-Gabriel does not trust Felix or Amelie, but to get them out of his hair, he makes sure they have what they need, and is more lenient when they ask for things. (despite hating them)
-Amelie isnt as insistent on the rings, since they moved in around origins and (she can get them later)
-Zoe goes to the same school Chloé does. Felix goes to the same one Kagami does. Adrien didnt want to go to a private school, he wanted to go to public school.
-Origins happens pretty much the same, Zoe was secretly impressed with Marinette.
-Felix totally finds out Adrien has a crush on Ladybug.
-Felix and Adrien have their birthday on the same day. (Idk if its true but I am going to say they do)
-Bubbler hits a bit different. Because Amelie is more on top of things. Making mention that Adrien and Felix's birthdays are coming up. Which has Nathalie remember to get Adrien a gift. (so she doesnt take Marinette's)
-Felix gets birthday wishes from his friends in London.
-Gabriel still refuses a party. And nino gets the harsh treatment.
-Lila does come to Françoise Dupont, but she is not in Ms.Bustier's class. So she doesnt have Adrien help her with her lessons. She ends up sucking up to Aurore and Mirelle, who she becomes best friends with (manipulation).
-Marinette isnt crazy about hearing Lila's lies about Ladybug, which is how she knew Lila was lying about everything, but she isnt furious about it and simply just tells Alya she should look into it more. People make up stories about Ladybug and Chat noir all the time. Which Alya does consider (since Marinette has no reason to be saying that)
-Evillustrator is altered, With the new addition of a classmate. The partners are pairs instead of groups of three.
-Marinette is paired with Zoe.
-This is where we get some development for Zoe.
-Marinette is left thinking that Zoe may not be as awful of a person. Since they actually get the project done.
-Felix and Kagami meet much earlier than Adrien meeting Kagami. Which interestingly has them hit it off once she kicks his ass. (Yes this au if Feligami)
-By the time Despairbear happens, Marinette and Company realize Zoe isnt like Chloé and try reaching out to her more. Juleka even invites her to the Liberty. (Potential Luzoe? Lukoe? Luzo? Zoka? Zoeka?)
