The Siege of the North (2)

Now in the Spirit World, Aang is told by Avatar Roku that the only spirit who would know where to find the moon spirit is Koh, the face stealer, and so Aang must now confront him. Back in the physical world, Zuko successfully kidnaps Aang's body but must wait out a snow storm before taking him to the Fire Nation. Meanwhile, Zhao, who knows where to find the moon spirit's physical form, sets out to kill it, hoping it will strip the waterbenders of their waterbending.
