Lornk doesn’t want Vic as merely his sex slave. He wants her as his, wholly and completely. Not because it suits his ego to have a young woman fawn over him, but because he knows something about Vic’s destiny, and he wants her to pursue it in a way that will benefit him.
In the Twenty-first Century we’re still blaming victims for not being pure enough. This same attitude in other countries leads to the sisters of rapists being raped in kind, as “justice” for the original crime.
