Overview
''Kuvira marches her entire army upon Zaofu in an attempt to coerce Suyin into surrendering the metal city to the Earth Empire, without having to take it by force. Suyin refuses, however, despite repeated warnings from both Kuvira and Korra, who went to Zaofu with Jinora, Ikki, and Meelo. Meanwhile, Varrick starts to get troubled by his conscience and refuses to further develop the spirit vine technology, though when Kuvira threatens to kill him, he continues his work to weaponize the spirit energy. After a confrontation with the Beifong clan, Bolin questions Kuvira's methods and he ultimately decides to betray her, joining forces with Varrick and Zhu Li in an attempt to escape. Their attempt is foiled by Baatar Jr., however, and while Zhu Li pledges her loyalty to Kuvira, Bolin is sent to a rehabilitation camp while Varrick is forced to continue his experiments. Korra tries to talk to Kuvira, though she is only given the chance to talk Suyin into surrendering Zaofu. When she returns to talk to the matriarch, she learns from Baatar that Suyin and the twins have snuck out to face Kuvira directly.''
