This is MCC so I'm probably wrong but...
The pop-up text offers this up as a possibility. Acting against it is that Miel has just been out for a bit of whoring, apparently in response to a hypnotic trigger, and that Patrick's "programming" of Klara appears to be setting her up to do similar work for him. In true SJI style, all we have is circumstantial evidence at this point.
For what it's worth, I don't think Patrick's fingers are instrumental here, since Klara has been submitting to his will from the moment they met in the shop. Either he has already been programming her previously, in which case he may have set up some visual or physical triggers, or else he simply has some power over women (or else, she's just playing along with his game). But if he has such a power, I doubt it's random. If he does have a blood connection to John Wilmot, then isn't it possible he's some kind of descendant of Atlas...? ("Titanomachy Property Management" in 368 suggests we're heading in that kind of direction.)
I'm partial to victims finding being controlled hot, but only if they are actually being controlled.
