He grudgingly does so.

Good.

Then they'll be taking their supplies and leaving.

Zhao lashes out at her as soon as she turns her back - 

And is immediately stopped cold by Iroh. 

"My niece has far more honor than you," she says, voice deceptively even. "You've lost, Zhao. Accept it."

And then they can leave.

This is why she hates the Agni Kai.

It's over now.

For now.

Let's get out of here.

As soon as they can - which is fairly soon; the men don't much like this port it turns out, and they're eager enough to go. And Iroh can resolve any problems with recalcitrant suppliers.

Zuko will delay going to hide in her cabin and having a breakdown until after they're underway.

Iroh takes over things smoothly and gives Zuko her space. 

She's back to normal the next day.

"How do you feel, niece?"

"Fine." A little paler than usual, heavier bags under her eyes.

She raises an eyebrow, skeptically. "What do you think of how the Agni Kai went?"

Mrr.

"I won."

"You did; you're a skilled fighter, and you handled Zhao's dishonesty well."

Right. So no problems, then.

"This was a more typical Agni Kai than what you - participated in - previously."

Zuko does not like thinking about her first Agni Kai.

"Zhao didn't honor his surrender," she says.

"Prior to that, at least."

"...I was expecting him to be better."

"As a firebender, or as a person?"

"As a..." person, "bender."
