"What do you mean, she's not here?" Zuko shouted at the guard, outraged. "Where is Azula?"
"I-I'm sorry, Your Highness," the guard stammered. "I-I-I was told you wanted her transferred to another prison…"
A look of worry spread across Katara's face. "What?"
Zuko glared at the guard with fury in his eyes. "Who told you that?"
"One of the new guards, Your Highness," he responded.
"I haven't hired any new guards recently…?" Zuko murmured.
"Is this some kind of sick joke?" Katara nearly screamed to the guard. "You just let some random stranger make off with one of the most dangerous people on the planet?"
"Katara," Aang said gently. "Calm down. Please."
"Don't tell me to calm down when my brother is missing!" she shouted, and stormed out of the prison chambers.
Aang sighed, and started to go after her, until Zuko held him back by placing a hand on his shoulder. "She needs to be alone," he told him. "Just let her cool off for a bit."
He turned to face him. "What she needs is someone to be there for her, Zuko," he replied harshly.
When Zuko didn't reply, Aang siftly turned around again, and went after Katara.
