So I know the producers have said Ali doesn't have a twin, but that doesn't mean she doesn't have another sister. Maybe Mrs. D had another girl who she gave up and this found her real mother and saw that Mrs. D had given Ali a perfect life. Then she got jealous and went after Ali. Mrs. D protected her because this other girl was still her daughter and she felt bad for giving her up.
