so....I asked this a few times already, but did anyone come up with an idea in the meanwhile why Geralt comments "Verbena" with "A-ha", when you visit Avallac'h's laboratory with Yen and Ciri? And Yen reacts quite annoyed by it?
It's Geralt reacting sarcastically, he literally says: "Herbs, not very incriminating", it is Geralt's shitty humour, Verbena is a normal healing plant in the Witcher world (from what I know) so all herbalists would have it.
