Several weeks later, Iroh and Zuko finally arrive at Ba Sing Se. They get work in the tea shop. Then Iroh gets his own tea shop. Then Zuko and Azula take over the city. They're running the city on their own authority, when about a week later, Zuko is taking a walk in the city. He's suddenly grabbed by the arm, thrown against a wall down an alley and a flame dagger is at his throat.

"I should kill you where you stand for what you've done to this city," the mysterious girl threatens softly.

"Who are you and what right do you have to treat the Fire Lord's son like this?!" he demands.

The girl smirks, "One who knows where to find your mother."

"You... You know where she is?" Zuko asks trepidaciously.

The girl nods and glares at him, "You will release the Fire Nation's hold over this city if you ever want to see her again."

Zuko just keeps staring at her. This girl, who is she? She seems so familiar... Mother, she knows where to find my mother. Or does she?

"You say you know my mother," he begins, "Then tell me, what is her name?"

The attacker simply replies, "Ursa."

Zuko gasps and demands, "Tell me where she is."

The girl just glares at him, "First the Fire Nation will leave this city."

"I don't have that kind of power," he goes on, "My sister, Azula, she could do it. However, I cannot."

"Leave Azula to me. She is no match," she comments.

"Fine, I'll do what I can. You take care of Azula. Then I get to see my mother again?" he asks cautiously.

The girl just nods.

"I'll go start this now," is all Zuko can say.

"Have Azula meet me in the courtyard of the palace," She demands.

"I'll convince her, what time?" Zuko inquires.

"At sundown," She states simply, "The perfect time for an Ag-Ni-Kai."

"How will you get into the palace?" He whispers.

"I have my ways," she replies.

"How do I know you're telling the truth about my mother?" He asks suspiciously.

The girl laughs haughtily, "You can trust me. I won't double cross you, and leave you to die in a prison."

Zuko gasps, but before he can say anything, the girl disappears.
