It is revealed that Aang is the Avatar, and this is the first time he goes into the Avatar State.
Just after Zuko breaks his spear Sokka's left leg appears to switch places with his right.
When Gran Gran is shoved back to Katara by Zuko, Katara's bun is white.
In the first shot of Zuko walking down the ramp of his ship towards the villagers, it shows four firebenders behind him. But when he reaches the bottom, there are three firebenders and three foot soldiers.
When Sokka stumbles while on the snow wall, the black triangle on his forehead temporarily vanishes.
As Sokka tells the children that Aang is banished, Gran-Gran's wavy design belt is straight but when the camera returns to Sokka, her belt has the wavy design again.
During the end of Gran Gran's farewell to her grandkids, Katara's braid is missing.
At the opening credits, it had the usual beginning, shorter than the first episode. But the beginning Katara already said that they found the Avatar, when it wasn't confirmed until this episode.
When Aang first goes into the Avatar state it is seen that his arrow is glowing. But when he comes out of the water it is not. Then when he lands on the ship it is glowing again.
Katara: How did you do that? With the water? It was the most amazing thing I've ever seen.
Aang: I don't know. I just sort of...did it.
Katara: Why didn't you tell us you were the Avatar?
Katara: (attempts to freeze the Fire Nation soldiers, but accidentally freezes Sokka instead)
Sokka: (chipping the ice away from him) I'm just a guy... with a boomerang... I didn't ask for all this flying... and magic!
Aang: If I go with you, will you promise to leave everyone alone?
(As Sokka and Katara try to catch up with Zuko's ship on Appa)
Sokka: Go. Fly. Soar.
Katara: Please, Appa. We need your help. Aang needs your help.
Sokka: Up. Ascend. Elevate.
Katara: Sokka doesn't believe you can fly. But I do, Appa. Come on, don't you wanna save Aang?
(Appa growls and swims faster)
Sokka: What was it that kid said? Yee-haw? Hup-hup? Wa-hoo? Uhh...yip-yip?
(Appa growls and takes off into the air)
Katara: You did it, Sokka!
Sokka: He's flying! HE'S FLYING! Katara, he's (pause)
(Sokka looks to her and she gives him a smirk)
Sokka: I mean, big deal, he's flying.
Zuko: Head a course for the Fire Nation. I'm finally going home.
Katara: Then we're in this together.
Aang: Alright! But before I learn waterbending, we have some serious business to attend to (points at map) here, here and here.
Katara: What's there?
Aang: Here, we'll ride the hopping llamas. And wwwaaayyy over here, we'll surf on the backs of giant koi fish. Then back over here, we'll ride the hog-monkeys. They don't like people riding them, but that's what makes it fun!
Prince Zuko (handing Aang's staff to Iroh): And take this to my quarters.
Uncle Iroh (to soldier): Hey, you mind taking this to his quarters for me?
Gran Gran: You'll need these. You have a long journey ahead of you. It's been so long since I've had hope. But you brought it back to life, my little waterbender. (She hugs Katara) And you, my brave warrior, be nice to your sister.
Sokka: Yeah... okay, Gran.
Gran Gran: Aang is the Avatar. He's the world's only chance. You both found him for a reason. Now your destinies are intertwined with his.
Katara (turning to the canoe): There's no way we're gonna catch a war ship with a canoe.
(Appa appears mounting the crest of hill in the background)
(She runs over towards Appa)
Sokka: You just love taking me out of my comfort zone, don't ya?
Sokka: All right! Ready our defenses! The Fire Nation could be on our shores any moment now!
(One little boy stops, raising his head and dancing about)
Little Boy: But, I gotta...
Sokka: (cutting him off) And no potty breaks!
Aang: Wow. I haven't cleaned my room in a hundred years. Not looking forward to that.
Iroh: Good news for the Fire Lord. The nation's greatest threat is just a little kid.
Zuko: That kid, Uncle, just did this. (looks around at vast damage to his ship) I won't underestimate him again. Dig this ship out and follow them! (In the background, some soldiers are using controlled firebending to thaw out their compatriots frozen by Katara) As soon as you're done with that.
Zuko: This staff will make an excellent gift for my father. But I suppose you wouldn't know of fathers, being raised by monks. Take the avatar to the hold. And take his staff to my quarters.
(Two firebenders escort Aang below the deck)
Aang: I guess you've never fought an Airbender before. I bet I could take you both with my hands tied behind my back.
(And eventually arrive at a holding cell. As the guard attempts to unlock the door Aang comes up with an idea.)
(Aang sneezes and with the force of his sneeze knocking the guards unconscious, Aang makes his escape)
Katara: We have to go after that ship, Sokka. Aang saved our tribe, now we have to save him.
Sokka: Katara, I...
Katara: Why can't you realize that he's on our side?! I know you don't like Aang, but we owe him!
Sokka: Katara! Are you gonna talk all day or are you coming with me?
Katara: Oh, Sokka! Thank you!
Sokka: Get in. We're going to save your boyfriend.
Katara: He's not my...
Aang: Hi, Katara. Hi, Sokka.
Sokka: Hi, Aang. Thanks for coming!
Aang: (to Zuko)Looking for me?!
Zuko: You're the Airbender? You're the Avatar?
Sokka: No way!
Zuko: I've spent years preparing for this encounter. Training, meditating- but you're just a child!
Aang: Well, you're just a teenager.
Gran Gran: Katara, you shouldn't have gone on that ship. Now we could all be in danger!
Aang: Don't blame Katara… I brought her there. It's my fault.
Sokka: Ah-ha! The traitor confesses! Warriors away from the enemy. The foreigner is banished from our village!
Katara: Aang is not our enemy! Don't you see?! He's brought us something we haven't had in a long time... fun.
Sokka: Fun?! We can't fight Firebenders with fun!
Sokka: I knew it you signaled the Fire Navy with that flare! You're leading them straight to us, aren't you?!
Katara: Aang didn't do anything! It was an accident!
Aang: Yeah, we were on the ship and there was a booby trap and, well, we boobied right into it.
Katara: Observe... the ancient art of penguin catching.
(Katara throws a fish at Aang, causing penguins to start racing towards him)
Katara: Why didn't you tell us you were the Avatar?
Aang: Because...I never wanted to be...
Sokka (knocks Zuko off his ship): Ha! That's from the Water Tribe!
