Fire swirled about him in all colours of the rainbow (red, blue, yellow, green), reminding Zuko of the four nations. This amazing form of fire was peace and harmony and balance and everything the world should have been.

As it surrounded him and the Avatar, he thought of his new comrades, the people he used to chase and would now do anything to protect. The extraordinary flame was just like them – a mix of completely different things working together seamlessly, as though part of one another.

The fire extinguished and the two dragons flew passed each other once more (red and blue), disappearing into their cave.

That moment stayed with Zuko for the rest of his life, completely changing his view of fire.
