It's long been said that any enemy of an enemy is a friend. But…Zhao and Zuko were both their enemies…and each others. So were they both friends? Both foes? Or what?

Zhao was their enemy, right? And Zuko was Zhao's enemy. So enemy of an enemy, right? But Zuko was their enemy also, correct? So did that make Zhao friend? And then you add Azula to the equation.

Azula was enemy. And Zuko was Azula's enemy. Zhao wasn't though. So Zuko was double their enemy's enemy? And Azula and Zhao were only singularly. And Zhao was dead?

Katara's head hurt.
