They leave the temple.

The hole in the ceiling lead to a corridor which brought the duo to another series of corridors, eventually leading them back to the entrance.

Appa was there waiting patiently for their return, so they boarded their flying friend and took off, ready to leave the temple far behind them.

For a long time they flew in silence, Zuko at the reins and Katara lying back in the saddle watching the setting sun. The warm breeze made the journey pleasant, almost drowsy. They flew like this for a long time, through the clouds and back to where they came from. Eventually when a few miles of sea and clouds separated them and the cursed island, Katara broke the silence.

"If you're alright with it, I have one more place in mind..."

Zuko looked back reluctantly, "Where, exactly?"

"Don't worry!" Katara reassured, seeing his **** to go on yet a third adventure in one already unexpectedly tiring day. "It won't take long, I just...want to clear my mind from all that before going back."

He nodded, still not enthusiastic about the idea but willing to land for Katara's sake. "Alright, where's it at?"

She directed him to another small island, however this one was alone and ignored enough to warrant map makers disregarding naming it. Big enough to have a small forest, small enough to be 25% beach. When they landed, Zuko threw together a fire and Katara replaced her water, then they both relaxed by the flames. Appa resting behind them, watching the flickering light with affectionate eyes.

"Thanks for taking us here." Katara said with a slight smile.

Zuko returned the slight grin, "I need to get my own thoughts in order too, that was a weird place...dragged up memories and feelings I wasn't prepared to face."

They sat in silence for a while, watching the flames eat through the fuel Zuko had found, falling into coals as the sky began to turn dark, crickets replacing birds as the sun disappeared across the horizon.

Eventually Katara leaned her head on Zuko's shoulder, fatigue threatening to crown their subconsciousnes control in temporary hibernation.

Or at least her's, Zuko's heart was beating a little quicker than normal and be knew they ought to go back now before the others became more worried than they probably already were.

"Hey," he nudged her slightly, "we should head back."

She wrapped her arms around one of his, her eyes closed as she squeezed him. "Zuko...I want to stay here with you."

He exhaled and closed his own eyes. It was really comfortable, he knew he could doze there in an instant if he wanted to.
