Zuko had been teaching Aang some fire bending basics. You watched off to the side thinking nothing would happen since Aang didn’t really understand. You turned your back for at least 2 seconds and once you turned back there was a big flame coming at you. You used your arm to cover your face and got burned pretty badly.

“I know it stings but don’t move”

Katara hovered her hand over the burn with some water. She was using her water bending to heal it. The burn ached and it looked horrible.
