Episode Title:
Harmonic Convergence.
Episode Description:
Senna tells Korra and her friends that the Southern resistance has been defeated and Tonraq captured. Meanwhile, Jinora nears death. With Harmonic Convergence hours away, Korra and her friends stage a frontal attack on the fortified South Pole, wherein everybody except Bumi is captured. Bumi infiltrates the camp and through a series of absurdest victories which mirror the supposed "tall tales" which he often tells, annihilates all opposition, freeing Korra and her friends. Korra and numerous of her allies follow Unalaq into the portal, while Asami takes an injured Tonraq to Katara for healing. While Tenzin, Kya, and Bumi seek Jinora, Korra goes to close the portals while Mako and Bolin hold off Unalaq, who reveals that he plans to unite with Vaatu to become a Dark Avatar and rule the world. Korra is too late to close the portal and Harmonic Convergence begins; Vaatu is freed for the first time in 10,000 years.
