When Sokka feels bad that he is not a master of anything - unlike Aang the Avatar, Toph the Earthbender, and his own sister Katara the Waterbender - he decides to master the sword. Disguising himself as a member of the Fire Nation, Sokka convinces Piandao, the master Fire Nation swordsman, to teach him the art. Piandao puts him through a series of exercises in order to prove himself, and eventually, Sokka is deemed a worthy sword master. But when he suddenly confesses to being from the Water Tribe, an angry Piandao challenges him to a duel! Who will emerge the victor?
