I don't understand why Prince Zuko has to argue with Princess Azula because they are siblings. Another thing that I don't understand is that how did Princess Azula get a "lightning bolt" power and Prince Zuko get a normal fire bending power? And why does Princess Azula have to have a scary face whenever she is angry. She doesn't sense any Spirit, then how would she have that weird face?!
