Weber: I mean, I can actually give you a very good answer, because it's the answer that Andrzej Sapkowski usually gives: the answer is in the books. And in the books, Andrzej Sapkowski called Ciri a witcher multiple times, and Geralt called Ciri a witcher in the books too. So I think that basically says what Andrzej Sapkowski thinks about the topic.
Sure, I've always called ciri a witcher too but it was with the knowledge that she couldn't even attempt the trials but still received all the training. WHY DOES SHE HAVE CAT EYES AND IS ALL THAT LORE OUT THE WINDOW
