So, Margot had a baby girl that's now 15 years old but she didn't want her because "she was just a child" at the time. Let's see now, when are you not considered a child anymore, around 18 yeah? That would make Margot around 33 years old present time. Even if she was 19, 20, the numbers would still not add up. Sonya Walger is beautiful and she's aging really well, but even with make up and a bit of imagination, it still makes for a plot hole.
