"Whoaaaaaaa!" yelled Sokka, clinging desperately to the sides of the frail-feeling box as they careened around corners. What kind of idea had it been to ride this "super-slide"?
In front of him, Katara was shrieking in terror, and Aang was whooping in elation. Sokka had to stop for a moment to ponder that.
Aang was definitely the most powerful of the three of them. And if he thought they were completely safe, he was probably right.
Suddenly, Sokka's fear turned into adrenaline. He trusted Aang with his life, and with his sister's.
So he settled back to enjoy the ride.
