How can you make avatar lover like me chose ONE single episode. That's like having some one chose between oxygen and life. yeah it doesnt make sense but it makes mypoint. YOU CAN'T DO IT!! but one of my favourites is The City of Walls and Secrets
This is such a hard question! One of my favorites is the beach, because it's both interesting and important. It was also the episode where Azula was the nicest (with out her evilness, she is almost perfect). At least that's my opinion.
