I didn't notice anything like that, honestly. The only difference I can think of along those lines is that the characters are more familiar now; they've had time to grow and so on. Their motivations are clearer, too, with factors like the Hunt and certain unwanted abilities shaping many thoughts...
Hello. :) I've only recently started reading the books, myself - I haven't met your favourite character yet, at any rate. I look forward to seeing her... and meeting the Aiel properly, come to think.
