There was a rueful expression on his face for a moment, and then he dropped off the rafter.

Down below, the front door of the bar opened and was left open for a moment, and a mountain breeze blew in, the summer wind carrying the faint smell of vines and sweet flowers, and lotus blossoms.

Then the door closed enough, and Aang jumped up with a little gust of air propelling him, and climbed back up onto the rafter, something clutched in his hand.

The Airbenders were gone, but in the temple, the flowers still bloomed--the apple and cherry blossoms that were there all spring and summer, the lotuses in the pools, the wildflowers on the mountainside--and it was a little bunch of flowers that he put down next to the plate of cookies.

"I don't know you, but I really hope that whatever it is...that it gets better, and that if you're worrying about someone else, that they'll be okay," he said. He was awkward again for a moment. "Things get better. They do."

Then he jumped off the rafter again, and was gone, the front door opening and closing again.

He'd left behind little white-pink apple blossoms.

For 'better things to come.'
