I suspect that Virginia Roberts' situation was a terrible one and she was vulnerable due to her age and maybe a need for a job. It's a shame her parents didn't talk her out of going in for the masseuse line of work, but perhaps they felt that role would offer her job security and a better life than otherwise. I think that Epstein's role was likely an horrendous one. I suspect that he might have wanted to have something on his male clients, to use as a lever later on, or for blackmail. I suspect he set out to strategically use Andrew.
I think that most royals must have potential girlfriends brought to them. I think they put out the word that they like a famous person's photo, or even a less famous person, and a contact known for making introductions, goes to have a word, and to see if there is interest in a rendez- vous. I expect that is how Harry met most of his slim, lithe- limbed beauties before Meghan. They were a pretty face and a pair of endless pins on a magazine cover or on TV, and he put out that he wanted a meeting arranged. That would be the only way they could meet someone who took their fancy - discreetly. So being set up with someone would be normal for Andrew. Would he see it that trafficking was involved? Did Virginia tell him that she was unhappy? Could he have shopped Epstein to the authorities for suspect behaviour?
I think everyone has to assume that a teenager involved in anything sordid needs protecting, whether they recognise that, at the time, or not. I don't know what happened between Andrew and Virginia, but I feel that if you see unescorted young girls in older adult company, that you should ask the authorities to do a welfare check.
