Do you know how long I've waited for this?
Since we were children, I was always the stronger. I was the one who stood by herself when you ran back to Mother.
But that wasn't right. You were the older brother. You were supposed to be someone I could look up to.
You weren't.
I was born lucky. You were lucky to be born.
I always pushed you, trying to press your buttons, make you lash out, prove that you were strong after all...
But you weren't.
Always you ran back to Mother for protection. Like a mother bear she guarded you, berating me for being so 'mean'.
But it wasn't right! I was the younger, you were supposed to be strong, courageous, my protector.
Sure, I didn't really need one, but it would have still been nice to know I had one.
If only you had been a few years older...
Perhaps they would have let you go off to war, and I could have pretended that you were strong.
No one ever protected me. It wasn't fair!
Father always favored me, but it was from afar. He was the Fire Lord, unapproachable, surrounded always by walls of heat. He was never there when I tripped and fell while trying to emulate Ty Lee, with her flips and somersaults and cartwheels; he was never there when I skinned my knees, was never there when I accidentally burned myself while learning how to firebend... not like Mother was for you. I held back my tears, learned to put up a stoic front, learned to ignore the pain.
Why couldn't you ever be strong?
But now... you are stronger. You must have changed somehow in your fruitless pursuit of the Avatar. For the first time, we fought together. I truly could not have won without you. That waterbender girl would have won if you had not stopped her. Saved me.
Perhaps I won't need to have you killed, after all.
Once I take the throne, perhaps I'll make you a general. Although I suspect the war will have ended by then, in our favor, I suspect that there will still be pockets of resistance.
You can protect both me and the Fire Nation, and everything will be right again.
You have regained your honor, my brother.
