Just what is he up to and why? Why did he kidnap Appa and when is he going to realize that you can't just brainwash someone into thinking that the Fire Nation doesn't even exist?

Personally, I can't stand that guy. He bugs me big time. I don't understand what kind of game he's playing, though. Does he want to become the King of Ba Sing Se? He certainly has a lot of power and influence in the city. I believe that Aang will kick his butt when it comes to a fight, but why do you guys think??Long Feng??is doing all of this? It seems like something??someone from the Fire Nation would do...
