In our season finale, the fire nation makes its attack on the northern water tribe. Aang journeys through the spirit world and temporarily fuses his soul with a fish. We discuss the moon and ocean spirit and the meaning of the word "faustian".This is episode 18 of Avatar: The First Viewing, the podcast where two first time viewers and a series veteran watch Avatar: The Last Airbender from start to finish. We go episode by episode to recount Aang's story. If you're a fan of ATLA or The Legend of Korra — or are watching for the first time — join us as we recount the series!
