--> "WHY AM I SO BAD AT BEING GOOD?!?"

After the devastating failure of the invasion, the gang and their remaining allies need a place to shelter, so Aang takes them to the only safe haven he can think of; [[TitleDrop The Western Air Temple]]. They know they have to re-group and think up a new plan for defeating the Fire Nation, but Aang doesn't seem to want to talk strategies: after another failure, he finds himself trying to escape his responsibilities. The fact that he still needs to practice Earthbending and ''begin'' Firebending also hits him full in the face, especially considering that there's no one to teach him.

Good thing that Zuko's changed sides and willing to help him, right? Wrong--the Gaang are none too eager to trust him, and the runaway prince must convince them otherwise.

!!Tropes:
* AccidentalTruth: Katara thinks Zuko, when he was the Blue Spirit, only freed Aang to capture him for himself. Well...that part technically is right.
* {{Adorkable}}: Zuko gets some major cuteness points here.
* AnswerCut: When Sokka muses that there has to be someone who can teach Aang firebending, it [[CutApart cuts to]] Zuko practicing his speech to the gang.
* AwesomenessByAnalysis: Sokka gets this more often than anyone in the series by virtue of being a BadassNormal and TheSmartGuy, but he gets a ''really'' good one here by calculating the exact angle he needs to throw his boomerang and hit Combustion Man right in the third eye.
* BigDamnHeroes: The Gaang were too busy tending to Toph's wounds after Zuko accidentally burned her to notice Combustion Man sneaking up on them, and preparing to fire. Good thing Zuko was here to make up for his mistake.
* {{Bizarrchitecture}}: The Western Air Temple is hanging ''upside down'' from a cliff.
** In the commentary, Mike and Bryan note that this could prove quite a problem to M. Night Shyamalan's live action adaptation. Of course, this was before the first film of that adaptation flopped so badly that the other two were scrapped.
* BothSidesHaveAPoint: Team Avatar is split over whether or not to accept Zuko as a firebending teacher. Aang is in the middle and inclined to listen to Katara and Sokka. The arguments are as follows:
** Katara and Sokka bring up that Zuko has a ListOfTransgressions that involved chasing them around the world; when he was offered a chance at redemption in Ba Sing Se, he turned it aside in favor of helping his sister conquer the city; and he hired an assassin that's been chasing them.
** Toph, the only Gaang member to not suffer personally at Zuko's hands (not counting Combustion Man), brings up that personal feelings aside, Aang needs a firebending teacher and one has showed up on their doorstep offering his teachings. Her lie-detecting abilities also sense that Zuko is completely honest in his quest for redemption, and he did free Appa.
* CallBack:
** Part of the reason why Aang accepted Zuko as his Firebending teacher is because he realizes Zuko feels genuinely sorry for accidentally burning Toph. Aang himself did the same thing [[Recap/AvatarTheLastAirbenderTheDeserter much earlier]] to Katara. Both Aang and Zuko know that fire is a wild element, and how it feels to accidentally burn someone you love.
** Zuko's attempts to hunt the Gaang through Season 1 are brought up when he approaches them.
** As is Aang using frogs to cure Katara and Sokka's fever in [[Recap/AvatarTheLastAirbenderTheBlueSpirit "The Blue Spirit"]]. Apparently Sokka was convinced he caught something from the frog.
** Zuko also tries pointing out how Aang thought they could've been friends. After everything that's happened, though, Aang's not willing to trust him.
** Katara's reaction to Zuko appearing is identical to her reaction to seeing Jet in Ba Sing Se. She doesn't like people who betray her trust.
** Katara clearly remembers how her trusting Zuko led to him betraying her and Aang, which led to Azula nearly killing the Avatar. At the end of the episode she reminds Zuko about what happened the last time he got tempted to do bad, and she will kill him if he hurts Aang.
* ChirpingCrickets: Done with a badgerfrog.
* ComicallyMissingThePoint:
-->'''Sokka:''' "You sent Combustion Man after us?!"
-->'''Zuko:''' "Well...that's not his name, but..."
* DeclarativeFinger: While Zuko is doing an Uncle Iroh impression.
* DidYouJustPunchOutCthulhu: Sokka, a BadassNormal, kills Combustion Man by hitting him in his third eye; when Combustion Man tries to use his powers, his powers backfire, blowing him up.
* DiggingYourselfDeeper: Yeah, Zuko, mentioning the assassin you sent after them was ''not a good idea''.
* DisorganisedOutlineSpeech: Zuko's initial attempt to make his case to the Gaang.
* TheDitherer: Aang, in the wake of the failed invasion. Every time Katara tries to get him to sit down with the others and talk about a plan of action, he brushes them off and starts goofing around. It's not until Zuko makes his presence known that he stops.
* FlashbackWithTheOtherDarrin: There are two flashbacks of pre-Season One Zuko and Iroh, but Iroh is voiced by Greg Baldwin, since {{Creator/Mako}} had died.
* FreudianExcuse: Discussed.
-->'''Toph:''' Considering his messed-up family and how he was raised, he could've turned out ''a lot'' worse.
-->'''Katar:''' You're right, Toph -- let's go find him and give him a medal: the Not-As-Much-A-Jerk-As-You-''Could-Have-Been'' Award!
* HeelFaceTurn: Technically it happened in the last two episodes, but it's nice to see it sticking. [[{{Deconstruction}} The hard part is convincing his former enemies that he's good]].
* HeroWithAnFInGood: Zuko has shades of this.
-->'''Zuko''': Why am I so bad at being good!?!
* IceCreamKoan: Zuko fails at mimicking his Uncle's proverbs. (Although what he comes up with actually makes some sense, given what he's gone through.)
-->'''Zuko''': Even when I'm impersonating him I have no idea what he's saying!
* IfYouEverDoAnythingToHurtHer: Non-romantically - Katara uses this on Zuko regarding Aang at the end of the episode.
* IronicEcho. From the flashback.
-->'''Zuko''': The only way to regain my honor is to find the Avatar.
* KubrickStare: Katara also uses one of these.
* {{Leitmotif}}: Zuko briefly gets Iroh and Azula's when he imitates them.
* LickedByTheDog: Appa licks a reformed Zuko to show he likes him. Sokka thinks he just covered himself in honey.
* ListOfTransgressions: When Zuko attempts to apologize to the Gaang, both Katara and Sokka bring up his past actions: chasing them around the world, invading their village, and stealing Katara's necklace and using it to track them down. Katara later on brings up what happened in Ba Sing Se, namely Zuko betraying her during the fight with Azula.
* LivingLieDetector: Toph's ability to tell when people are lying comes in handy trying to defend Zuko, since none of the others believe him.
* LockedOutOfTheLoop: Seems like the Gaang didn't fill Toph in on as many of their earlier adventures as she would have liked, as she's visibly annoyed when the rest of the Gaang mention [[Recap/AvatarTheLastAirbenderTheDeserter Jeong-Jeong]] as a possible firebending teacher for Aang.
-->'''Toph:''' Who's... oh, never mind. If it's important, I'll find out.
* NeverSayDie: If Zuko goes for another spin on the HeelFaceRevolvingDoor, Katara will "make sure his destiny ends". Though that was more about her using Zuko's meaningful words against him, since he'd been going on about that. It's not like they've ever beat around the bush about the other stuff.
* PetTheDog: Deconstructed -- the Gaang are unimpressed that Zuko has "done some good things," like freeing Appa from the Dai Li.
-->'''Sokka:''' Oh, hurray! In a lifetime of evil, at least he didn't add Animal Cruelty to the list!
* PoorCommunicationKills: Toph goes to talk to Zuko while he's resting, but doesn't announce her presence until a spooked Zuko starts firebending, even though before that he'd loudly asked who was there. It gets her feet burnt, though Toph doesn't hold a grudge for it, and tries downplaying Zuko's actions when telling the others (even blaming herself and saying Zuko burning her was an accident).
* ReformedButRejected: Zuko gets this treatment until the end of the episode, at which point people begin to relent. Except Katara, who keeps it up for four more episodes.
* SayingTooMuch: Zuko mentions he sent Combustion Man after the Gaang. It doesn't help their already sour mood.
* SpellMyNameWithAThe: The Duke is insistent on that.
* WhatTheHellHero: Toph calls out her friends for not even considering accepting Zuko as Aang's firebending teacher, despite him being the only viable choice aside from Jeong Jeong. She may not have had any history with Zuko, but she understands the bigger picture and knows that there are bigger stakes than their personal feelings.
* WhatWouldXDo: Zuko asks himself what his uncle (and, for the sake of argument, his sister) would do. (Complete with impersonations of both. He does a dead-on Iroh.)
* WoundedGazelleGambit: Sokka thinks Zuko's pulling one of these with his redemption.
