Did you not pay attention? she literally tells the MC to be confident and aggressive then "do whatever with her, anytime" and she enjoys being dominated. I mean, she blatantly comes out and says it clearly several times. Besides that, when bob and linda speak about their past, they both go into how bob was much more dominant and aggressive in their youth, which is what she enjoyed about him.That was the biggest mischaracterization I've seen in a good long while.
A domineering woman, who has been aggressive about what she wants with her son, stating that it's the best sex of her life. You're saying that she is actually hoping to be "grabbed [...] by the hair, slammed [...] against the wall [...] and would totally start acting better." WOW
I seriously don't think you know these characters at all or maybe have a very skewed view of the world.
WOW.
Maybe pay more attention?
