Episode Title:
Light in the Dark.
Episode Description:
Tenzin and his siblings find Korra and her friends wounded and unconscious. Once healed by Kya, Korra states that with Raava gone the cycle is over and she is now likely the last Avatar. Unavaatu attacks Republic City. During the attack, Varrick escapes prison. In the Spirit World, Tenzin leads Korra to the Tree of Time and tells her to meditate within it. As she meditates, Korra unlocks previously untapped spiritual potential and teleports to Republic City to discover a fragment of Raava within Vaatu; the spirits of light and dark 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 Harmonic Convergence to re-merge; the Avatar Spirit is reformed, but Korra's link with the previous Avatars appears to remain lost. After deep 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 end their romantic relationship, but pledge to remain friends. Korra, no longer the bridge between the two worlds, declares that the world has entered into a new age.
