because that’s actually not in the books lol.
i honestly hate the show because it’s not at all accurate to the books either in spite of that being the bulk of their marketing. that said, the two swords things comes entirely from the games. in the books he makes comments a few times about the fancy metals in his swords helping kill monsters, but he only has one at a time.
always more complicated than the headlines would have you believe.
hell, Geralt spends damn near a quarter of the series straight up disarmed. one of the books is basically a legal drama about him trying to not go to jail after getting his sword stolen. don’t think he has his sword for about 99% of that one.
“gotta get my fuckin sword back” is a very common plot point throughout that series. not just for Geralt. ciri spends some time sword chasing too. i don’t hate it.
