Sokka really likes Earth Rumble. She finds herself getting really worked up with each match. But when the champion ends up being a short young blind girl, Sokka is beyond surprised. She stops cheering so loudly for the Boulder, and keeps her eyes on the girl. She wants to see how The Blind Bandit has become the champion. The way the girl takes out the Boulder so swiftly really impresses Sokka.
Before there's too much time to be impressed though, Aang is challenging the girl to a fight. It doesn't really seem like his style, but Sokka watches on curious. Air versus Earth doesn't last too long, because Aang knocks her out of the ring quite quick. Sokka's pretty excited about winning the gold though.
The next day the trio finds themselves at the Beifong home. Their first attempt at entry doesn't go too well. Of course, when Aang pulls the Avatar card, things get a little easier. They end up being invited to dinner. Dinner sort of ends up being a mess, but Sokka doesn't mind too much. She mostly just sits there enjoying the fancy food.
The good times don't last very long because Toph and Aang end up getting kidnapped. They get out all thanks to Toph. Even though her parents originally object to Toph coming along with them, later that night they change their minds, and the group gains a new member.
