Recap / Avatar: The Last Airbender "The Firebending Masters"
Having been accepted by the Gaang, Zuko begins to teach Aang firebending, only to discover that his own firebending has gotten weaker. Realizing that he previously fueled his firebending with hate and rage, Zuko takes Aang to visit the ruins of the ancient Sun Warrior civilization in hopes of learning a new way to firebend.
- Call Back: The red and blue dragons resemble the ones Zuko dreamed of in Season Two, representing his good and evil sides.
- Contemplate Our Navels: Trapped in goo with no way to escape, Zuko suggests this to be a good way to pass the time.
- Continuity Nod: Aang's expression when he firebends, as well as the slo-motion, is virtually identical to when he first firebent in "The Deserter". Only this time he is in full control.
- He refers to Zuko as 'Sifu Hotman'
- Deadpan Snarker: When Zuko comes to the revelation that true firebending is supposed to be modeled off energy flow, like a sun inside you and asks the chief if they knew this:
"Well our civilization is called the Sun Warriors... so, yeah."
- Death Faked for You: Iroh did this for the last two dragons.
- Didn't Want an Adventure: "You had to pick up the glowing egg, didn't you?"
- Don't Touch It, You Idiot!
- Durable Deathtrap: Aang nearly gets killed by one. Subverted in that the trap probably wasn't that old...
"Zuko, I think the past is trying to kill me!"
- He Knows Too Much: Subverted; after claiming that discovering the continued existence of the Sun Warriors (and the last two dragons) means Zuko and Aang can never leave the tribe, the chieftain then reveals he was just kidding. Then Double Subverted when he rather freakily insists they don't tell anyone what they've seen and learned (since their lives and especially those of the dragons depended on secrecy).
- Hidden Elf Village: The supposedly-extinct Sun Warriors are still living in their apparently ruined city.
- Le Parkour: Zuko runs on the wall to get past a trap.
- Psychosomatic Superpower Outage: The reason for Zuko's firebending getting weaker.
- Ragnarok-Proofing: Subverted. The Sun Warriors are still alive.
- Raiders of the Lost Parody
- Redemption Demotion: Ultimately inverted, as Zuko proves to be an even better firebender after this episode, but first played straight and discussed when his bending initially becomes much weaker.
Zuko: I bet it's because I changed sides.
- Sins of Our Fathers: Invoked by the Sun Warrior chief, who pretty much says to Zuko that he's off to a bad start with the last two dragons, because Zuko's great-grandfather Fire Lord Sozin was the one who started the act of hunting dragons as a sport, causing the race to go nearly extinct. Eventually subverted when the dragons deem Zuko worthy of learning the true ways of firebending.
- Stealth Insult: "You know, Zuko, I don't care what anyone says; you're pretty smart." It takes Zuko a few moments to understand the implication.
- Theme Tune Cameo: The Sun Warriors play the drumbeats from the closing credits music.
- Took a Level in Jerkass: Katara shows this when she rather nastily taunts Zuko for losing his Firebending.
- "World of Cardboard" Speech: Both Aang and Zuko knew from near the start of the episode that their blocks to learning firebending were internal, but it's not until the near the end that they actually give the speech and break through the blocks.
