Sometimes when Aang was in trouble, Sokka didn't hesitate to join the fray. Other times, like this, all he could do was stare.

They trusted Zuko. He'd proven himself a friend – right?

Aang hadn't been fighting lately. He'd trained hard, but only with friends. He hadn't needed sharp reflexes. The flames spread; Sokka found himself worrying. What if Aang couldn't beat Zuko this time?

Then it happened.

"ENOUGH!"

The shout rattled the whole house, shook the floorboards. The others stared on in shock as Zuko was blasted through the wall and into a tree.

Sokka wasn't worried anymore.
