I am answering your "Tsunami, Turtle, and Willow" and "Moon's final words" questions. Considering Tsunami and Willow, I think and hope that she DESTROYS Willow. I thought Icewings were my least favorite tribe, but the Leafwings are a whole new level of dislike for me. I personally hope that if they challenge the other dragon tribes the other tribes will set fire and ice, venom and all the strong muscles to the Leafwings. That's the only thing that I mostly agree with Queen Wasp on: the Leafwings should be ERADICATED. Sundew is fine, I guess.... but everyone else is a no-no.
Moon's final words probably meant that everyone was going to escape Pantala and go to Pyhrria or that Blue, Cricket, Sundew, and Swordtail (who I assume is going to get into a lot of trouble the next book) are going to venture to Phyrria for some reason... probably to find Luna or to escape a flaming Pantala.
