3. The Coronation

Complete story — includes the ending

At Wu's coronation in Republic City, Kuvira refuses to yield power to him, instead announcing that she will consolidate the territories under her control into a new Earth Empire. This creates a rift between her and the other world leaders including Suyin, as well as between Bolin and Mako, who has to protect the unpopular Wu from angry supporters of Kuvira. Meanwhile, in the banyan swamp, Toph agrees to help Korra regain her strength, though her methodology largely consists of browbeating Korra and beating her up with still formidable earthbending. She finds residual metal poison inside Korra but can't remove it – Korra subconsciously resists, scarred by her previous traumas. Meanwhile, Tenzin sends Jinora, Ikki, and Meelo to search for Korra, and Varrick experiments on spirit vines for Kuvira.
