"And even despite all this, Zyn still cares enough about his brother to instantly freak out when the latter is in trouble. Did Stouffer truly not get what children and sensible adults would conclude from all this? Geeze!"

No. She really doesn't. She's got to be worse than Stephenie Meyer in that regard.

"*raises hand* Question. Given the fact, mentioned early in the book, that all Muggles are bald, shouldn't hair, any kind of hair, be a kind of marvel to them? So, why do they consider Rah's blond hair to be better than Zyn's red hair? Does not compute."

Well, I kind of got the feeling that it was Stouffer herself who thought that Rah's blond hair, blue-eyed appearance was nicer. Which just raises all sorts of unfortunate implications.
