Idiot Savant
There was just no getting around it. Sokka was an idiot. But he was a brave idiot and in that light Suki could tolerate him. Kyoshi Islanders valued courage beyond gold. It (along with sheer bloody-mindedness) had kept their home safe from the outside world and their ships safe from the Unagi. That Sokka was a humble idiot was nothing short of amazing. Traveling with the Avatar, Suki had expected the older boy to be arrogant and while he did not disappoint, he could admit when he was wrong and make amends for himself.
In that light, she could love him.
