Somewhat wryly: "He's considered very skilled."

Skeptical Zuko.

"You've been training under me, niece. I'm not just legendary for my tea making skills."

"Still."

"You're a better firebender than you think," she says, softly, "Certainly a far better one than Zhao."

"You're a better person, too."

What?

She raises an eyebrow, questioningly.

"What- what makes you say that?"

"As a firebender - you've got good control over yourself and your flames. You don't just rely on your flames when fighting, and instead maintain awareness of and use your body and surroundings. You watch your opponent well, and you don't fall for traps."

"As a person - you have a tremendous sense of honor, Zuko." A bit wryly: "Far more than I've ever had. You fight for what you feel is right, and you fight fairly."

"I don't feel like I'm a good person."

"Why not?"

"Because-"

"I've never been good enough."

"How good of a person you are - doesn't affect your luck. Not in the way we'd like it to."

"Then what's the point?"

"How we treat others, and how we view ourselves."

Mrr.

"...It's a lot to think about - I'll understand if you need time to process and think of a response."

"I- Yeah."

Iroh can handle the leading the ship parts - they're underway, so there's not much to do - if Zuko wants to go meditate.

No, she'd rather be busy.

Then she can definitely find things for Zuko to do.

Good.

The only major thing left is deciding where they go next. 

The Avatar was heading north. They should follow.

'North' covers a lot of territory.
