1. I think the caves were their the whole time. That part of the story was never to clear to me though as in did the Dragons used to live near the castle and then get driven away? Or did they always live in the caves but then Bahamut fought his way through and hid the tail in some random old castle purely for his trail?

3. Given the choice, probably, but at that age I didn't have a choice and my Mom got me a cabbage patch doll whether I wanted one or not.

4. Not only did she wear the pants, she made Yang do the laundry too!
