Many_Fandoms_Fangirl
To anyone that remembered that one time I posted about someone not knowing Marinette was lady bug until the later seasons I figured out why now. Seems like they were part of the role play side of the Fandom. So they were accustomed with playing in different Aus and since multiple people back then wanted ro play both Marinette and Ladybug, they split all the superhero and supervillain aliases apart to give everyone an equal chance. So they who joined that RP group got so accustomed to the idea that Marinette and Ladybug were two people. (They admitted that they hadn't watched the show much mostly edits and memes) So when they watched a miraculous ep in season 4 they had the sudden realization.
