How does the song go? It's a long, long way to Ba Sing Se, something, something, something, Take me down to the walled city/Where the grass is green and the girls are pretty.

Bumi hums loudly, shifting his weight to gently swing the metal coffin the Fire Nation has him imprisoned in. It's not time. It's so far from time it's not even funny, but he was bored. A little bit of swinging never hurt anybody.

A girl walks out onto the rooftop below. Dark-haired and her hands pulling a shawl tight around her shoulders like it's cold. She tilts her head up to look at him, and the moon comes out from behind the clouds.

The shawl is silver fur. Silver seal fur, he realizes with a sinking heart. They found the skin he'd been entrusted with, the one he's supposed to return when Pakku finds Kanna again. So his friend can give it to the woman he loves.

It's been sixty years since that night. Sixty years, and Bumi can feel the dust collected in the silver fur. It's almost enough to pull on, if he had hands free to move.

The Fire girl touches the sealskin and says nothing. She doesn't stroke it or fondle it or do what so many others with selkie skins do. It is a light touch, a glance of fingertips.

Bumi almost dares hope as she turns away to go inside.
