We’re nearing the end of the first season of Avatar: The Last Airbender. Here’s the 18th episode of that season – The Waterbending Master.
Description: Finally reaching the North Pole, Aang finds a Waterbending Master.
However, the Master refuses to teach Katara because she is a girl. Meanwhile, Sokka spends time with Yue, Princess of the Northern Water Tribe. Admiral Zhao hires the pirates (from The Waterbending Scroll) to assassinate Zuko while he prepares a massive fleet to invade the North Pole.
