The Blue Spirit

After Sokka and Katara get sick while they are journeying to the North Pole, Aang seeks out a cure and discovers he needs some frozen toads in order to get them cured. Meanwhile, Zhao has been promoted to Admiral and he is using the Fire Nation’s best men to capture Aang, which turns out to be bad news as Aang is captured while trying to get the toads to cure his friends. All hope seems lost for Aang and his friends, but there may just be a glimmer of hope when a strange masked figure comes to Aang’s rescue, but who could it possibly be?
