The Legend of Korra Episode 1.09 Out of the Past

Tarrlok hides Korra in a remote mountain cabin, publicly claiming that Equalists abducted her. In response, Lin Beifong breaks Korra's friends out of jail and, with Tenzin, they infiltrate the Equalist hideout, only finding Lin's de-bended police officers. Back at City Hall, a witness exposes Tarrlok's crime and Tarrlok escapes to his cabin using bloodbending. There, locked in a metal box, Korra has been meditating to gain a more complete vision of Aang's past: Forty-two years ago, the mobster Yakone escaped his trial by bloodbending the court into submission, but Aang recaptured him and removed his bending. Korra deduces, and Tarrlok confirms, that he is Yakone's son, repeating his father's attempt to rule Republic City. Equalists arrive at the cabin and Tarrlok's bloodbending proves ineffective against Amon who removes his bending. Korra escapes the Equalists, barely avoiding Amon. In the woods, the weakened Korra is found and rescued by Naga, who carries her to the city where her friends find her.
