In the show's three seasons, many of the main characters on "The Witcher" have grown and evolved quite a bit since the first season. However, it can be argued that few have come nearly as far as Cahir, a high-ranking Nilfgaardian intelligence officer and one of Emperor Emhyr's most trusted allies. In Season 1, he was charged with capturing Princess Cirilla of Cintra and bringing her back to Emhyr. Throughout the season, Cahir appears to be a true believer in the Nilfgaardian cause, never questioning his loyalty to Emhyr or his belief in Nilfgaard's mission, despite all of the brutality he has witnessed, and been a part of, in Emhyr's name.
However, things begin to change after Cahir is captured in Season 2. While escaping the Brotherhood's custody and smuggling himself back to the Nilfgaardian-held Cintra, Cahir spends a lot of time hiding among different peoples, especially the elves. Upon returning, he appears softer and more lenient towards those who are not in line with all of Nilfgaard's beliefs, including the mage Fringilla.
In Season 3, Emhyr asks Cahir to murder Gallatin, an elven warrior he befriended. He carries out the deed, but it becomes apparent that the decision weighs heavily on him. When meeting with Emyhr, Cahir asks, "You said you knew a good leader when you saw them. How?" This might indicate that Cahir's loyalty to Emhyr as a leader might finally be waning.
