So, Aang had more dimensions than Sokka had thought.

Not only was he caring enough to want to end a hundred-year feud, strong enough to go without food and still fight off dozens of canyon-crawlers – he was also smart. That plan he'd thought of, to ride out of the canyon? Brilliant! And the lie he'd concocted in two seconds that had successfully ended aforementioned hundred-year feud?

It was a little annoying, since Sokka had considered himself the smart one in their group. Still, leaving the Great Divide behind, Sokka really appreciated why the spirits had chosen Aang as the Avatar.
