But if i had to be serious about this show, i would be saying this show has to much retcons, bc on S1 was said by Ruby that Ashley had one step mom and 2 step sisters in SB, yet Anastasia was on wonderland that was frozen in time just like SB.
She could still have memories of another stepsister as Ashley Boyd. It was mentioned that she doesn’t speak to either of her stepsisters, after all, and being in Wonderland would prevent that.
