Alright, upon watching the "Warriors of Kysohi" episode, I noticed something, hilarious.

When Katara is talking to Aang about the stuff getting to his head, it goes to show Aang talking, and in the background, there's this guy. At first, he's staring at a house with his hands up in distress. It goes to Katara, and then back to Aang, and you see the guy holding his hands over his face as if crying. After another scene with Katara, it goes to Aang again, and the guy is all balled up on the ground.

I think someone put it on Youtube... Maybe search "Warriors of Kyoshi"?
