Sozin's Comet, Part 2: The Old Masters

After June is unable to track down Aang, the gang decides they must find the only other person alive who could help them defeat the Firelord; Iroh. They find him on the outskirts of Ba Sing Se, where he has gathered the Order of the White Lotus, an ancient society which transcends the division of the four nations, to free Ba Sing Se from the Fire Nation. On the island, Aang seeks guidance from his past lives, but is not happy with their advice. Soon after he discovers that he is not on an island at all, but on the back of a Lion Turtle, whose advice aids him greatly.
