This scene is from Avatar: The Legend of Korra episode "Korra Alone" in which during the final scene of the episode, Korra sees an old woman talking about she rescued her from the mud pool and then tells her to listen her senses if the spirings led her there, surprising the Avatar and prompting her to ask how she knew of her identity. The old woman ultimately reveals herself to be none other than original Team Avatar member Toph Beifong, who addresses Korra as "Twinkle Toes", a nickname she gave to Korra's predecessor Aang in the original series.
