Something someone who's not on the wiki mentioned to me: Maybe Anastasia (or whatever they name the other stepsister) is "missing" is because she was the thing Lady Tremaine loved most, and so she was sacrificed for Lady Tremaine to cast the curse. I thought this would be a really clever way to incorporate her, so we don't wind up with a Clorinda and Tisbe situation, where Tisbe just wasn't in present day and no one cared.
