"Slow and boring."

"There's nothing wrong with that!"

Dechen giggles. "And Appa hasn't even shown off their loops yet!"

Interested noise! 

"I think we should tie the canoe down more securely before we do any loops." And maybe also the Taqqiq. She maybe be Boomerang Girl, but she's not a boomerang girl. If she falls off the bisoncat, she's not coming back.

"We can wait until you and the canoe are safely on land, even," she teases.

"That would be nice."

"Never say I don't look out for my big sis."

"Uh huh."

She laughs. And to Dechen: "Where were you going originally?"

"Oh.. I was- looking for a... waterbending teacher."

"You're a waterbender?"

"Sort of."

"You don't look much like a waterbender."

"How can you be 'sort of' a waterbender?"

"Well, actually...."

"I'm the Avatar."

" - What, really?"

"Mhm," she nods. "I already mastered airbending, that's why I have the tattoos. Next is supposed to be water."

"Can you prove it?" Also she wants to see airbending.

"Which part?"

"The all of it."

"I can do some airbending for you, at least. Watch this." She holds her hands out one above the other like she's holding something invisible, then starts wiggling them in small circles going opposed directions. A faintly-visible globe of moving air begins to condense between them, whistling softly. Once it coalesces fully, Dechen changes the pattern slightly and the whistle begins to play a tune.

Cool!!!

What happens if she sticks her hand into the spinny ball?

It feels like it's trying to get blown off her wrist. Also the music is disrupted.

Awww...

She pulls her hand back out.
