Plot
Tenzin and his siblings, Kya and Bumi, find Korra, Mako and Bolin wounded and unconscious in the Spirit World. Once healed by Kya, Korra states that with Raava gone the cycle of the Avatar is over and she is most likely the last Avatar. Meanwhile, Unalaq, now bonded with Vaatu, attacks Republic City. Tenzin leads Korra to the Tree of Time, where Vaatu was previously imprisoned, and tells her to meditate within it.

As she meditates, Korra unlocks previously untapped spiritual potential and teleports to Republic City. She discovers that a fragment of Raava lies within Vaatu, as light and dark cannot exist without each other and one will always regrow from within the other. Jinora's spirit shows Korra where it is, and Korra removes Raava from Vaatu, killing Unalaq and defeating Vaatu.

Tenzin, Kya, Bumi, Mako, Bolin, Desna and Eska defend Korra's body from dark spirits attacking them. Korra and Raava return to the Spirit World and use the Harmonic Convergence to re-merge, reforming the Avatar Spirit. However, Korra's link with the previous Avatars apparently remains 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 decide that they have end their romantic relationship as it does not seem to work out for them, instead opting to remaining friends by doing their last kiss, but always be there for each other.

Critical response
IGN's Max Nicholson rated the episode 9/10, praising the action, the plot, and the music, but criticizing the scene where Jinora's spirit shows Korra that Raava is still within Vaatu, noting that "it really doesn't make that much sense". Writing for The A.V. Club, Emily Guendelsberger agreed with Nicholson that some scenes didn't make sense, but still described it as a finale that is "sort of a perfect encapsulation of the second season".
