Team Avatar decided to travel to Ba Sing Se in order to tell the Earth King their plan to defeat the Fire Nation. However, they ran into an Earth Kingdom refugee named Than, who, along with his sister and pregnant wife Ying, were traveling to Ba Sing Se after losing their home to the Hundred Year War. The group agreed to escort the family to Full Moon Bay so they could get a boat, but the family's passes and luggage were stolen by thieves and they were all forced to cross the Serpent's Pass instead. The group was joined by Sokka's friend Suki, a member of the Kyoshi Warriors who was overseeing the bay's security. After several nights of close calls along the pass, the group came face-to-face with the serpent itself at the only water passage through the pass. Katara and Avatar Aang succeede
