The "Legend of Korra holds a lot of new and exciting plots including that of Korra and Bolin learning how to bend metal.

As producers and writers prep for the imminent release of the third book of the Legend of Korra, spoilers have surfaced and revealed that on the sixth episode entitled "Old Wounds," Korra and Lin Bei Fong will stay in the metal city of Sao Fu where Lin's half-sister's family resides.

Spoilers said that Su became mixed up with members of the Earth Triad, which led her to be arrested by Lin. The leaked information also confirmed that it was Su who gave Lin the whip-lash scars on her cheek. Meanwhile, Toph intervened on Su's arrest and drove Su away by saying never to come back to Republic City. Because Toph was the Chief of Police, she could not have a daughter in prison.

In "The Legend of Korra" Book 3, Lin and her half-sister Su will be engaged in a fight and it will reveal that Lin and Tenzin used to be in a relationship, but that Tenzin had broken up with her. Meanwhile, during their stay in the metal city, Korra and Bolin will learn the art of metalbending.

On the other hand, Nickelodeon teased fans with the first trailer of "Legend of Korra" season 3. The trailer was released by the Korra Nation Tumblr to the delight of many fans. The trailer also features Korra, Lin Bei Fong and Asami who rise above the rest.

In the video, Korra is seen fighting with green-clad woman. A young woman with an eye tattoo on the forehead was featured in the video as well as an older woman who might be Earth Queen. Returning characters include airbending Bumi, Eska, Skoochy and one who looks like Zuko. It seemed that Korra will face a lot of challenges and new villains in the third installment of the popular animated show.
