Sorry if this is a bit tldr.
I will try to explain what I said, however my answer may not satisfy you. I am aware of what you are refering too, but I can't say I paid much attention to it. Possibly I should have anticipated something being brought up about it but the thought never crossed my mind.
Anyway I just felt that for the most part the characters in the book acted more or less as I felt they should given what part of thier thoughts I was privy too. When I said that I had in a mind a specific book that could be considered somewhat similar in which I felt the characters did not act as I would expect them too according to thier personalities. That is the best I can do without going back and rereading the book.
