Retrospective-Avatar: the Airbender Book 1, Chapter 7-The Spirit World
I never realized before now, but this episode is very important for the season. The A plot introduces the Spirit World (though not as cool as it will be later) and gives Sokka a great character moment where he refuses to let Aang face the threat alone, damn what anyone else says. The B plot, however, totally steals the show for me. It gives us the confirmation of Iroh's badassery, Zuko chooses to save his uncle over chasing the Avatar, and in the final fight Iroh steals the show without Firebending. He kicks the ass of a squad of Earth Kingdom soldiers with the chains they put on his hands. On the whole it is a damn good episode, very funny and cool. Laters.
