Avatar: The Last Airbender, Book 2: Earth

Ozai:
Father, you must have realized as I have that with Lu Ten gone, Iroh's bloodline has ended. After his son's death, my brother abandoned the siege at Ba Sing Se, and who knows when he'll return home. But I am here Father and my children are alive.

Azulon:
Say what it is you want!

Ozai:
Father, revoke Iroh's birthright. I am your humble servant, here to serve you and our nation. Use me.

Azulon:
You dare suggest I betray Iroh, my first born, directly after the demise of his only beloved son?! I think that Iroh has suffered enough. But you, your punishment has scarcely begun!
