[A moving rock is something Katara is a lot more comfortable with - so she just studies the movements and the rock for a moment, rapidly trying to match up what she's seeing with her experience.]

So - it's the words that you're saying and the way you're moving that stick? Can you do that with anything, or would you have to use different words to move something else besides a rock? [And something she wouldn't have thought of before she came to Luceti:] Is it something you have to be born with, or can anyone learn?

[Meet Katara - girl of a hundred questions.]
