I should add that those who knew something was up didn’t necessarily know all the details - whether she would actually die, be injured, by whisked away, or what.
And very, very few would know where she was whisked away to.
Once she had a new face and physique it could reach a point where she COULDN’T whistleblow, even if she wanted to, because there would not be a way to prove who she was.
Particularly if she was hypnotized into believing her new, false identity was who she really was...and had no recollection of her life before she was fished out of the water and re-engineered into a new life form?
Butter, you simply CANNOT be serious...
