This post by SakuOtaku about the themes in Iroh’s story in season 2, episode 15 “The Tales of Ba Sing Se” is quite touching. Avatar: The Last Airbender really is a beautiful show!

Iroh’s Story in Avatar: The Last Airbender
Especially poignant because that episode was a farewell to Mako, the voice actor for Iroh, who died. That’s the main reason Iroh didn’t talk at all during the 3rd book; they didn’t want to try to recast the voice actor. I think he only spoke one line when Zuko broke him out and begged for forgiveness and I’m 99% sure it was something Mako recorded before his passing.
