Avatar: The Last Airbender Season 3 Episode 5 : The Beach
Zuko, Azula, Mai and Ty Lee go on vacation to Ember Island against their wishes. They try to act like normal Fire Nation teens but have little success. They reveal their inner problems and discover more about each other. Meanwhile, Aang and friends are attacked by Zuko's assassin, "Combustion Man" (nicknamed by Sokka for his ability to channel and cause explosions through his third eye).
