Iroh: Someone new must take the throne. An idealist with a pure heart, and unquestionable honor. It has to be you, Prince Zuko.
Zuko: Unquestionable honor? But I’ve made so many mistakes.
Iroh: Yes, you have. You struggled. You suffered. But you have always followed your own path. You’ve restored your own honor. And only you can restore the honor of the Fire Nation.
