"AHHHHH!"

The yell woke Sokka up – but he was used to it. Aang's sleep was constantly plagued by nightmares. He rarely spoke of them, but everyone knew they were there.

Because Katara was gone, Sokka supposed it fell to him to comfort Aang. The Avatar sat alone rubbing his eyes, shoulders hunched.

"Hey." Sokka sat down next to him. "Want to talk about it?"

"Not really," said Aang miserably. But he looked at Sokka pleadingly. "I can't fail again, Sokka."

Sokka saw the pain in Aang's eyes, and put an arm around his shoulders. "You won't, Aang," he muttered. "Promise."


So, this one takes place when Katara and Zuko are gone.
