Let's get back on topic.
Future (as in "unaired, unconfirmed") episodes listed at IMDB are fake; anyone can submit them- they started a game about this at the Avatarspirit forums. They're a great way to have fun, but they can't be trusted as legitimate. Some of them I wish were true, but there's no way. The summaries are basically lists of the most commonly used fan fiction devices: canon Zuko/Song, return of Jet, debut of Jojo and Malu, Koh steals Katara's face, once there was a return from the dead by Zhao and Yu?? in the same episode along with flashbacks of Iroh's surrender at Ba Sing Se and Lu Ten's death.. Overkill. No self-respecting writer would try to fit such things into 22 minutes.
