Still reeling from the loss of Appa (although Aang insists he's fine), the gang realizes that they will need to take a ferry to get to Ba Sing Se instead of just flying. However, a young couple, one of whom is pregnant, has their passports stolen, so is not allowed on the ferry. Our heroes promise to help them across the treacherous "Serpent's Pass"; they're also joined by Suki, who's been helping with the war effort. Zuko and Iroh, who do take the ferry, and meet another familiar face in the form of Jet; together they help 'liberate' some food.
