Honestly to me if she were to do that, the charachter would be dead to me. As horrible as what she's doing to Will is, I do think its a situation she found herself in. She thought she was pregenant, and then discovered she wasn't and didn't know how to tell Will. To lie and say she lost the baby? Aboustly inexcusable its just horrible.
Well I'm pretty sure that's not worse than convincing an 18-year-old to give up their baby
Or, pretending to miscarry then trying to get pregnant again.
If she's retarded enough to but on a fake belly to make her husband keep believing she's pregnant,
pretending to miscarry isn't that much of a stretch for her.
