The Legend of Korra/Recap/B3/E01 A Breath of Fresh Air

Two weeks after Harmonic Convergence, portions of Republic City have become covered in spirit vines and after Korra cannot remove them, President Raiko expels her from the city. Around the world, people begin to spontaneously develop the ability to airbend. Tenzin, Korra, and her friends embark on an airship trip to attempt to recruit these people into a new Air Nomad nation. Meanwhile, the dangerous criminal Zaheer (Henry Rollins) escapes from a remote prison thanks to his own new airbending skills.
