Here we find out that Mrs. Robinson’s real name is Elena Lincoln (is that American enough?).
We could go into a debate over the ethics and morality of a sexual/BDSM relationship between an adolescent male and an adult woman, whether it is intrinsically exploitative, whether we would feel different if the genders were reversed, and so on. That’s outside the purview of this blog. I will say that Ana’s feelings regarding this other woman aren’t driven by anything like that. They come from jealousy, pure and simple.
