This was something I did not notice until after I rewatched "Zuko Alone." The family that Aang and his friends escorted over the Serpent's Pass are actually recurring characters of a sort. If you watch "Zuko Alone" there is a scene in which Zuko is starving and then smells food. He sees a man by a campfire with meat roasting over it. Instinctively he reaches for his weapons to steal the food and potentially kill the man in the process. However, he then sees the man walk over to his pregnant wife and so Zuko spares them. A few episodes later, they meet again in "The Drill" of course they don't recognize him and it would appear that he does not recognize them either, but if you look at the scenes again, you will see that they look identical, not just similar but identical. LOL Anyhow, just an interesting tidbit I stumbled on when I was rewatching "Zuko Alone" after I had watched the two Secret of the Fire Nation episodes.

Copper for your thoughts.
