Sorry, I've had to push it back to this Friday or Saturday. Mid-week is very busy for me! On the bright side, all of August should go back to normal releases.
The dragon's absolutely bratty behavior is actually needed for plot consistency. The story especially made a point of the dragons being insufferable. This caused birds to form the conspiracy against dragons, making all capable predators concentrate their efforts on slaying dragons no matter what. The dragons became rare eventually. So, the dragons need to be like that, for the story to stay true.
