1) Winter Solstice Part II (Avatar Roku) - Everything started to make sense, and it's something spiritual and empowering in Roku's and Aang's conversation.
2) The Avatar State - We got to meet big bad Azula and her smart mouth.?? Also see Roku again and hear his teachings.??
Azula: Well, then, maybe you should worry less about the tides who???ve already made up their mind about killing you and worry more about me, who???s still mulling it over.
Roku: "?? It's time you learned.?? The Avatar state is a defense mechanism, designed to empower you with the skills and knowledge of all the past Avatars. The glow is the combination of all your past lives, focusing their energy through your body."
3) The Blind Bandit -??We got to see Toph for the first time.?? Money isn't everything.?? I liked seeing exactly how she uses her other senses to battle and function.?? Her fight scene with the boulder was hot.
