I thought it was good, as usual. And the twist...was well done...! My only comment is that maybe, perhaps you should've saved it up a little longer, dropped hints and then thrown the swerve...? Because that was a big revelation.

Also, I was thinking, maybe something that could add spookiness to the whole youth deal with her, and be a part of this edge she has, is if maybe she found herself addicted to looking at violent pictures or something like that, or some sort of wholly morbid fixation...?

To me, I'm impressed when Wild comes off so...evil/sociopathic/sick that you're actually turned off, even though you realize she's this hot woman.

My other thought is that, you know, any old guy might have Hustler. But, if he had something that only a serial killer would have, that could fixate Wild...some artifact of what he was, that she kept, as a kid, be it drawings, a journal, whatever...?
