hi people im new 2 this but i luv the avatar any ways i wanna tell u all about the ending in book 1 chapter 3 the southern air temple. At the end of the eppisod aang looks bak into the clouds but if u look closely u can c at the top of the screen are 2 clouds 1 is shapped like a serpent and the other is shape like some dud wif pointy hair. But the real question is hoo r they well ill tell the clouds r in the form of rokus dragon and roku himself.
