The sixth episode of the third season of the show, 'The Avatar and the Fire Lord' explores the history of the avatar-verse and the unique relationship between Avatar Roku and Fire Lord Sozin. Similar to the episodes 'The Storm' and 'Zuko Alone', the episode is heavy in flashbacks, using them almost exclusively. Unlike the previous two episodes, however, these are not the memories of any of the main characters, and are all delivered post-mortem.
