|Zukko went to face off against his sister, Azulu, and sided with Aang's group against her. Azulu then shot their uncle in the chest and ran off when she knew she was outnumbered... Zukko rejected Ktarra's offer to use her powers to heal him.. wtf what an idiot..|
Aang's group finds a hidden library in the desert, guarded by a giant owl who is the spirit of knowledge or something... Sakka finds out that fire benders lose their powers during a solar eclipse, just like how water benders lose their powers during a lunar eclipse... and that another solar eclipse will happen in a few months.
While they were in that library, their bison Appa got kidnapped and sold to the earth kingdom city. Now they have to go to that city not only to find Appa, but also to tell the Earth nation king about the fire benders' weakness. This earth city is closed off with a great big impenetrable wall, and the government there is brainwashing its citizens into thinking there is no war..
Meanwhile, Zukko and his uncle also go to the earth city as refugees, and get jobs in a tea shop. Jet, that guy who hates the fire nation enough to destroy a whole town of them, finds out these 2 are actually fire benders, but nobody will believe him.
