I feel like people here underestimate just how underhanded and vicious Rose is. She's not some beat junkie bimbo getting turned out to get her next fix, she's a mother who's trying to get her child and herself out of danger. A few weeks ago she was a typical repressed housewife in a dead marriage with a loser husband, and now her whole world's been turned upside down.
Edwin is very susceptible to Rose, due to his own mommy issues and with Rose being in the same situation Vicky was when Edwin was a boy. But I believe Rose only sees Edwin as a useful idiot out of who she can fuck favors and help. It's a shame that Rose doesn't know about Vicky's circumstances, or she would be able to manipulate Edwin much more effectively.
Much like Vicky learned to enjoy the gangbangs and humilliation once she let go of shame and inhibitions, so does Rose start to enjoy her own humilliation, and the little slave/master relationship she's fostering with Edwin, as evidenced by her lust stat. But just as Vicky let go of her porn career and returned to normal life unscathed, Rose will want to forget about the Club as soon as she cashes out, and resume her normal life. And at the end of the day Edwin is just another one of her tormentors, who's also good friends with Ian, who has extensively tested Rose out before she got the gig. I doubt Rose cares about Edwin's petty struggles that led him to the club, especially given the gravity of her own situation.
Also, do you people actually think that Rose will let her daughter anywhere near a freak like Edwin, who's morally grey at best. I just think our boy Edwin shouldn't be surprised once Rose skips state after she gets the cash. The age gap is the least of their problems.
