Masochist + Twisted + high PClove + high PCevil = ...something awe-full to behold, I'm sure.
You could actually have a couple girl traits show up based on her relation to the PC, and if we do implement PC stats (still not sold on that, btw), on the PC's stats. i.e. reverse what I did above - high PClove and PCevil could result in the Twisted trait, or high PClove and high PCgood/low PCevil could give a Motherly trait or something.
I don't even really want to comprehend what a girl with maxed-out PClove, PChate, and PCfear would end up with...
