Yeah, and it's the one NO ONE thinks would do that, since so many people love her, so it would actually make a much bigger impact that the ones already mentioned. It would also make sense why she's been so nice to mc and why she was so willing to take him in without a second thought. Worst of all, we don't know anything about her past, and if she's the secret woman on the will, it wouldn't be out of the realm of possibilities for her to appear nice and never show signs of manipulation, while in reality, everything she did was apart of her stipulations.
