14. Light in the Dark

Complete story — includes the ending

Tenzin and his siblings find Korra and her friends wounded and unconscious. Unavaatu attacks Republic City. During the attack, Varrick escapes prison. In the Spirit World, Kya heals Korra, whom Tenzin leads to the Tree of Time, telling her to meditate within it. While meditating, Korra unlocks previously untapped spiritual potential and teleports to Republic City to discover a fragment of Raava within Vaatu; both spirits cannot exist without each other and one will always regrow from within the other. Jinora's spirit illuminates the fragment, and Korra withdraws Raava and purifies Unavaatu, killing Unalaq and defeating Vaatu. Tenzin, Kya, Bumi, Mako, Bolin, Desna and Eska defend Korra's body from attacking dark spirits. Korra and Raava return and use the Convergence to re-merge; the Avatar Spirit is reformed, but Korra's link with the previous Avatars appears to remain lost. After some contemplation, Korra decides to leave the spirit portals open, believing that spirits and humans can find a way to coexist and should be allowed the chance. She also declares the Southern Water Tribe to now be independent from the North as its own state. Korra and Mako break up, but pledge to remain friends.
