Usually, if Sokka staid awake to keep guard, he did so alone. Now it changed. Zuko decided that he'd keep him company. It wasn't something Sokka expected, but he didn't protest. His sister and Aang joked he must be sick and were rather certain Zuko was.
"I feel like I shouldn't have suggested helping anybody," the prince muttered gloomily.
Sokka blinked, and then slapped his own forehead. Sometimes, he really thought he was the only person with a brain here.
"Don't hurry so much," he replied, grinning in a way which he thought was mysterious and wise. "Girls don't like it."
Zuko glared at him. He clearly missed the fact that it was a joke and he assumed that Sokka was making fun of him.
"Ha-ha," he answered dryly. "You could have said you don't want company. I wouldn't have minded leaving you alone and letting you bore yourself to tears."
"I was joking, Your Highness," Sokka replied sounding insulted. "Geeze."
"Well, I don't have a sense of humour."
They sat in silence for some time, both annoyed. Finally, Sokka decided he should make matters clear, since he was the one with more sense than temper.
"They're not used to you trying to help," he said trying best to sound nonchalant. "Have some patience."
Judging from Zuko's expression this thought didn't occur to him.
