Aang and Sokka behold a Fire Nation train while discussing the unfortunate absence of their friends Katara, Toph, and Appa, all of whom had their own reasons for staying behind. During this conversation, Aang spots a young girl standing alone in the crowd just as a man signals that it is time for boarding. After introducing himself and learning the girl's name, Sho explains that because her mother is sick, she must visit her grandmother's house alone. Aang proposes that he and Sokka ride the train with her, a plan that Sho and Sokka welcome with open arms.
