Our heroes leave the Northern Water Tribe so that Aang can begin his search for an Earth Bending teacher. Aang begins to feel guilty and overwhelmed by the sheer power he holds, and the fact that he has killed people while under the control of the Avatar State. At the same time, they meet a general who urges Aang to learn to control that very state's power instead of focusing on the four elements, so that the war can be won quicker. Zuko and Iroh, meanwhile, are outcasts, without their ship; at least until Zuko's sister Azula comes welcoming them back to the Fire Nation with open arms.
