Sokka couldn't believe how good it felt to be hugging Appa again. But he knew that for all his delight, Aang must be even happier.

He looked up; Aang was splayed over Appa's forehead, hands wound into his fur. Tears were streaming down his cheeks.

Sokka let go of Appa and went to join Katara and Toph at his feet. Katara was looking at Aang, too, her face soft.

"It's good to see him happy again," she murmured, only loudly enough for Sokka to hear.

He looked up at Aang, and back at his sister, then nodded.

"Yeah. It is."
