"Metal? No, no. There's only one person in the world who can bend metal, and that's my friend Toph. I'm a waterbender." It's not so surprising, really, that he doesn't know what a bender is (and she has no idea why people would even want to bend spoons), so Katara shimmies past him into the hotel's hallway. "I'll show you!"

Once there's enough distance between them that Steve won't get splashed, Katara pops the cap off of her waterskin. With a sweeping gesture of her hand, a stream of water flows out of the pouch like a sinuous liquid snake. It loops into a ring and then twists into a figure-eight.

"Bending is using your chi to manipulate the elements. Where I'm from, there are four kinds of benders: earth, water, fire, and air."
