Total necropost, but I'm surprised they never blamed Ax's behavior on Tourette's. Or they did and I missed it XD
I find that I understand Ax's point of view far better than the other characters. Or I can understand where he's coming from in terms of not understanding social behavior. I have a mental disability that affects social understanding and interaction, so I look at the world a lot like he does when he first came to Earth, and I've lived on Earth for 30 years.
And I'm sure Elfangor had trouble controlling his human morph at first, too. KA just glossed over that part of his life in the book.
