"I'll behave."

"Good."

She squeezes Zuko's hand again.

"We'll have to deal Zhao first, though."

"The Avatar might make that easier, actually..." To Iroh: "Zhao's planning an attack on the North Pole. He's also planning to press this ship into service - likely onto the front line."

She nods, solemnly. "You'll want to be careful in foiling the attack," she warns, "Especially once it's fully in motion."

"It'd be nice to stop it before then."

"We'll need to work quickly."

"What do we need to do?"

They'll need to get out of this port, first - it'll be bad if Zhao catches them here.

It'll be a little suspicious to set sail so soon, but if it's the crown princess's order...

It is.

Can't argue with that.

After that - Azula could probably challenge Zhao to an Agni Kai for command of the fleet, though at that point she's committed to either completing his mission or turning the fleet around in open rebellion. 

A North Pole invasion wouldn't be a very good start to peace talks.

No. So they'll need a different method, or to go ahead and start their rebellion.

...How much is she starting her rebellion just by sailing off on Zuko's ship?

...Only a little bit. 

What if Zuko challenged Zhao to an Agni Kai when he tries to commandeer the ship? She's beaten him before, she could do it again.

Is she willing to kill him? 

She's not sure.

He won't stop if he's alive. 

Yeah. She's- seen some of that.

Azula will handle killing Zhao if Zuko can't.

"I have the standing to challenge him to an Agni Kai as well. I have no issue with killing him."
