Book 4: Kuvira is a fascist who unites the Earth ... trains to let go of Earthly attachments, but he's also the "Legend of Korra" villain whose words and actions feel the most tied to our world.

After Korra’s battle with Zaheer at the end of Book Three, it took her three years to recover. Hence the big time jump heading into Book Four - which now looks to bring the epic journey full circle.

As the second episode of Book Four, this episode proved just how powerful animated storytelling can be as we found out what exactly Korra had been up to during that three year time jump.
