Astrid Mikaelson

Everyone knows Esther being the mother of Freya, Finn, Elijah, Klaus, Kol, Rebekah and Henrik right? Well what if Esther isn't really their mother and she has another sister? Esther took her sister's children and husband away wiping their memories of her completely. But what Esther didn't know was that every time they get daggered or the longer they are daggered, they get their memories back of their real mother. They get Esther to confess why she did it. It was out of jealousness.
