Quarter: You don't have to screw Triss.
Fenixp: Let's just say that it's easy to separate people who red the books from those who haven't ;-)
I haven't read the books, and even I was picking up on some pretty obvious clues that there was history with Triss. That said, am I the only one a little creeped out by how focused on having sex with everyone Geralt is? I'm not a prude when it comes to sex, but realizing that Geralt was ok with taking up the witch's offer to have sex with her as an incentive to not turn her over to the villagers... I don't know, that seemed a little rapey. This woman genuinely is afraid that she will die if the locals get her (which is a valid fear), and she is at a point where she is offering herself to Geralt in order to try to avoid dying; that's not exactly a scenario where someone can be said to have formed consent.
edit: sorry about necroing, didn't see the date until I posted.
