Avatar: The Last Airbender Season 2 Episode 20

Well, this is an emotional episode in a different way. It made you engage throughout the whole episode; Azula's cunning and arrogant attitude in addition to Zuko's "betrayal". Zuko was just shaping up to be a really likable character, until he decided to team up with his most hated sister. Though half of the episode consisted of awesome and jaw dropping fights between Zuko and Azula vs. Aang and Katara. The creativity, sheer aesthetics and production values, it was all almost too perfect. You'd wish for a typical Hollywood ending, but the rather morbid ending is also a good thing; makes you curious how Aang and the rest of the world is going to handle such a predicament in their hands now that nothing stands in the fire nation's way.
