The Avatar State

Aang is haunted by the thought of reverting into the Avatar State, fearing he won't be able to control himself, and tries to avoid it at all costs. The gang travels to the Earth Kingdom to meet with a general who plans on using the Avatar State to beat the Fire Nation. Meanwhile, Zuko and Iroh are visited by Azula, Zuko's sister, who tells them they are finally going home. However, Iroh is suspicious.
