I don’t think Ella’s stepdad is Ana’s and Drizzy’s Father. Could be, but it depends on how much older Ella is. Actress-wise, Dania is about a decade older than Adelaide, but the kid versions of the three sisters from a bad perspective look roughly the same age.

So, Ella had to be really young (and Stepdad just told Ella about her), because Ella in the flashback appears to be about the same age as Ana and Drizzy.
