Because of the game’s AI making the characters behave in a generic manner, the characters in the game (frequently) do things that they would never do in the show, even make impossible friendships for the sake of being generic decorations!
Neighsay: “Why, little cow, are you lost? Perhaps I shall find your father and send you home, so never to trouble our land ever again.”
I thought that Neighsay was just an overprotective guy, so he would have also been nice. Do you think he would have been rude towards poor Yona and the griffon nearby?
