"The Puppetmaster," which is the scariest episode

Sozin's comet. Avatar Aang.
He finds out in Season1 Episode 12 "The Storm"
Avatar the Last Airbender , Book 1 episode 14 - The Fortuneteller .
No, Ho' Wan Island Carnival wasn't actually an Avatar episode.
He gets hurt in Book 2, Earth, Chapter 8, when he is shot with fire by Azula after he, Zuko, and Team Avatar had her cornered in the Earth Kingdom. That happens at the very end of the episode, which closes by showing Zuko very distraught at his uncle's injury. Chapter 9 continues with Iroh having a dream about his beloved son, Luten, when he was still alive as a child, and then waking up to find Zuko tending his wounds. This is about the only time in the entire series that I can recall Iroh sustaining an injury.
the episode after the drill is 'The City of Walls and Secrets"
No , some theaters are showing "Avatar" only in 2D .
