I feel like there are some really great characters that get introduced just to disappear. Zzabur is an amazing character. I really wanted to see him parade around as Ian for a few days, then maybe pick someone else to become. I wouldn't mind seeing that for a week or even two. Can't some of the siblings start coming back occasionally?
how long has the series got left? because on the main page the news bit says its nearly over. maybe there just isn't time to have the siblings for very long anymore.
