Once again people like you miss the point. I don't care if Cait sleeps around, I was fine to treat her as a cumrag from the beginning. The thing that annoys me is the stuff Savin puts in to make implications that we're suppose to be more than a fuckbuddy to her but still want to fall back on her just being a whore. Pick a lane already.
It's almost like relationships can change, or something. Crazy.
As for other stuff where she sluts it up, Savin is not the only scene writer; there's other ones who would be like "yeah let's include Cait doing horny Cait things" and there ain't much Savin can do about it unless he openly goes "okay no more messing with my OC after this point in the character questline". And the nature of the game means not every character who cameos in someone else's scene is gonna behave the same exact way.
If you need her to stick to her guns, then don't enable her attitude shifts, this is all optional stuff here. No one will say "YOU MUST MAKE CAIT THE MAIN HEROINE FOREVER OR I WILL SLAP YOU WITH MY DICK."
So you wind up the person who takes her anal virginity; she still treats it like the "friends with benefits" zone, so if you really still think that's "too much into the other lane" cool. Don't do butt stuff with her. Better yet, avoid engagement with her.
If that's still me not "seeing the point", then the point is
there is no point. This is dumb.
