Iroh can take the bright-eyed, eternally fascinated treatment from the Earth King on a lot of things, but not about Lu Ten. Lu Ten's memory is not something for someone to peer at as if it is a bug stuck through with a golden pin under glass. It is one thing to do his best to improve the Earth King's knowledge of his history and, in doing so, to improve relations between their two nations; it's another thing to discover that the king has been so protected from everything, his whole life, that his responses to the tragedy of others are completely inappropriate.

I keep thinking that there were so very many refugees into Ba Sing Se that they are the ones, for the most part, living in that new section and the sections around it. Iroh suspects that if he ventured further out, he'd find people who lived there when they were children, but even with his penchant for penitence he doesn't want to see their scars.
