Looking for Bolin, they stumble through a city that Mako barely recognises. Panic transmutes them into endless reflections of the same street, a nightmare of blank faces and unfamiliar buildings.

They pass a park with a statue of a boy wielding hooked swords, an entirely new sight down a street Mako swears he’s known all his life. They ride Naga down dark alleys and crumbling slums, buildings that recall pictures Korra has seen of Ba Sing Se, and early photographs that Mako’s mother kept from the Fire Nation.

In the industrial district, they find the factory that makes the metalbenders’ uniforms, and the great golden prows of the Fire Nation fleet. They have tea at an Earth kingdom stand Bolin would have loved, run by an elderly lady who calls herself Song.

They pass shrines and shops and factories, slums and sprawling houses. Mako calls for Bolin until his throat is raw, and he finds himself a stranger, lost in a city he has known all his life.
