Her words seem to suggest that it is the doctor telling her that her man may have needs she can’t satisfy, so… what are those needs? Theoretically they’re sexual given the context, but what could he need that she can’t provide? Why is a different woman needed for them?
I think you've just exploded the myth of extramarital affairs. I may be wrong but my guess would be that the point is not the truth or specific implications of what she's saying, so much as the fact that she accepts it to be true. I suppose that the more important the identity of her husband actually is in this dream, the more likely I am to be wrong about that.
It seems to me that Erin is being brainwashed to become a sexual object/domestic servant who believes any memories she retains of a past life in which she was a powerful witch and in love with Adrian were delusions. She will happily provide everything her husband needs, but not out of love, only out of duty - and specifically because this is one of the duties assigned to her by the doctor. I don't think she's necessarily being programmed to suggest to her husband that he should have a girlfriend. Rather, she is being programmed to accept so completely that a man cannot be satisfied sexually by just one woman that she would actively
want her husband to have other women. After all, it is her duty to ensure that he is always sexually satisfied. And why should she care? She doesn't
love her husband and she doesn't need
his love, even if he has any for her. She's only here because it's her duty to service his needs.
When 'domesticated' first came up in 1334 I immediately thought of Yves and his beauty supplies business, because I've long wondered if (hoped) he dabbles in the supplying of the occasional beauty too. (This goes all the way back to the twin Princess Pink blondes in 82 with the van parked outside.) I don't think it's going to happen, but this brainwashed Erin could easily be sold off as a bride to the highest bidder.
Regardless, this programming does suggest to me something different to "Erin is returned to Adrian believing she's his nineteen-fifties wife and much hilarity ensues."
I'm interested in the doctor figure. Ostensibly he is responsible for her brainwashing. But to all intents and purposes, as far as Erin is concerned, he is merely a representation
of her brainwashing in human form. Is there actually going to be a doctor? Is Miriam the doctor? Is the doctor merely an idea in Erin's mind - a non-existent, untraceable figure, nonetheless completely controlling her in her new life? That she recalls willingly being fucked by even this phantom might demonstrate the extent to which she believes she exists to be sexually exploited.
As ever, I find myself not so much rooting out the truth as exploring the possibilities I find the hottest. Watch now in the next page as she introduces Dinah, the golf pro with the nice pins from down the street who could really help him with his swing.
