if you mean at the end of the novels, then yes he pretty much gave her up and his objective for the sake of ciri.
if you mean in the game... then, do you really want to get spoiled? But come on, we know in the novels that he cares so much for Ciri that he gave up all his machinations for her, you really think he would have ill intent on her?
of Ciri knowing he is her father... dont think so, although Ciri is a sharp girl with a REALLY good sense of intuition. wouldn't be surprised if she knew deep down inside but just doesnt want to believe its true.
Aha thanks!! ... What spoiled of? I was thinking of it,,what she deserves, that he wants to give to her in witcher 3? making her an empress? And yes I was like she would at least get that "familiar" feelings of meeting someone she knew!
