I have a question involving Anastasia from OUATIW. In my S2 of OUATIW, I was thinking of for the flashback in my S2 finale, I would explain Will and Anastasia's backstory that would featured characters from the first iteration of Cinderella. Anastasia would take the place of the stepsister known as Tisbe who made a minor appearence in S6 episode "The Other Shoe" due to runtime. I know that a crewmember tweeted that she met a duke, but they didn't said she married the duke. Anyway, my question related to a tweeted on October, 2016 made by Adam Horowitz that stated the Red Queen isn't the first iteration of Cinderella's stepsister. However, in an online podcast in November 2017, Eddy Kitsis stated that the Red Queen "would have been more tied" to the first Cinderella indicating that there is a connection between the two characters. So, my question is that does my idea of using the first iteration of Cinderella as the basics for Will and Anastasia's love story contradict the rules of the fanon season 8 and beyond board as its said to accept the show's canon from beginning to end.
Canonicaly, Lady Tremaine of the original Enchanted Forest had two daughters, Tisbe and Clorinda. So, it wouldn't be true to make them sisters. I guess, cousins or distant family members or neighbors or whatnot is fine.
