Hahn (to Admiral Zhao): Admiral Choi! Prepare to meet your fate. (Charges at Zhao and misses, falling to his apparent death)

Hama: I control every muscle, every vein in your body. It's impossible for you to escape my grip!
Katara: Stop... Please...

Haru: Come on. I'll race you, Duke.
The Duke: I told you, it's THE Duke!

Headmaster: Thank you for coming, Mr. and Mrs...
Sokka: Fire. Wang Fire. This is my wife Sapphire.
Katara: Sapphire Fire, nice to meet you.
Headmaster: Mr. and Mrs.... Fire, your son has been enrolled here for two days, and he's already causing problems. He's argued with his history teacher, disrupted music class, and roughed up my star pupil.
Katara: (in shock) My goodness, that doesn't sound like our Kuzon.
Headmaster: That's what would any mother could say, Ma'am, nonetheless you're forewarned. If he acts up one more, I'll have him sent to reform school [standing up for emphasis]! By which I mean the coal mines. Are we clear?
Sokka: Don't you worry, Mr. Headmaster! I'll straighten the boy up with something fierce. (in a fierce tone) YOUNG MAN, AS SOON AS WE GET HOME, YOU'RE GONNA GET THE PUNISHMENT OF A LIFETIME!
Headmaster: That's what I like to hear.
[Aang, Katara, and Sokka leave; with Sokka walking in a manly-like manner]

Hob Gao: (in gleeful anticipation) Ohhhhhhh, here it comes. Any moment now. Dinner for the Masters.
Sun Warrior Chief: Quiet, Hob Gao.
Hob Gao: (annoyed) What? Everyone's thinking it.

Iroh: Believe me when I say there is good inside him [Zuko]!
Sokka: Good inside him isn't enough! Why don't you come back when it's outside him as well!

Iroh: (After a group of children accidentally breaks a window while playing soccer) It is usually best to admit mistakes when they occur, and to seek to restore honor...
Very large man: (Yelling threateningly through the window) When I'm through with you kids, the window won't be the only thing that's broken!
Iroh: ...but not this time. Run!

Iroh: (as Zhao threatens the moon spirit) Whatever you do to that spirit, I'll unleash on you tenfold! Let it go now!

Iroh: (singing)
Leaves from the vine
Falling so slow
Like fragile tiny shells
Drifting in the foam

Iroh: (Sips tea) Blech! This tea is nothing more than hot leaf juice!
Zuko: Uncle, that's what all tea is.
Iroh: How could a member of my own family say something so horrible?

Iroh: (singing)
It's a long, long way to Ba-Sing-Se
But the girls in the city
They look so pretty--!
They kiss so sweet
That you really got to meet
The girls from Ba-Sing-Se--!

Iroh: (after diverting their ship to replace a lost game piece) I've checked all the shops on this pier. Not a lotus tile in the entire marketplace.
Zuko: It's good to know this trip was a complete waste of time for everyone!
Iroh: Quite the contrary. I always say, the only thing better than finding something you are looking for [crew members begin to walk past carrying Iroh's purchases] is finding something you weren't looking for at a great bargain!
Zuko: You bought a Tsunghi horn?
Iroh: For music night on the ship. Now, if we only had some woodwinds.

Iroh: (to Zuko) Would you like some tea?
Zuko: We've been working in a tea shop the whole day. I'm sick of tea.
Iroh: (stops making tea and lifts his hands in exasperation) Sick of tea? That's like being sick of breathing!

Iroh: After the duel, the Fire Lord said that by refusing to duel, Zuko showed shameful weakness and so he was banished and sent to capture the Avatar.
Lt. Jee: So that's why he's so obsessed. Capturing the Avatar is his only chance he has of things returning to normal.
Iroh: Things will never return to normal, but the important thing is the Avatar gives Zuko hope.

Iroh: Good news for the Fire Lord. The nation's greatest threat is just a little kid.
