Last one. I got the idea from Pride and Prejudice. I know it's in the movie, but I can't for the life of me remember if it's in the book. I haven't read it in over a year.
"Now that we are married," Zuko said, turning his head to look at Mai, "you will be known as the Fire Lady."
"Yes, but not until you are the Fire Lord. Your uncle still has quite a few years ahead of him." Mai reminded him.
"If I know my uncle, he'll probably change the rules. He's not really one to take power to the grave like my father and grandfather." Mai laughed at this comment, and leaned back into his arms.
"That's Fire Lady Mai to you." She corrected him.
"But I thought not until I was Fire Lord," Zuko said, looking slightly confused.
She flashed him a look and merely laughed once more.
"I need to ask, then, when I can refer to you as Fire Lady Mai," He said thoughtfully.
"Let's see, when I am completely and utterly happy, when I am completely and utterly bored, and when your sister is around." Mai replied, though monotonically.
"So, every moment of every day?" Zuko asked.
"No. I shall only be called Mai when I am unhappy, entertained, or not around Azula. And I don't see your sister anywhere."
"Well then, Fire Lady Mai, I shall do as you please. But keep in mind that my sister has only to do with part of your name-calling."
"However, I myself would like to be called Fire Lord Zuko when I am in a good mood, Zuko when I am not, and Lord Zu-Zu around my sister."
Just for this moment
"Whatever you say, Fire Lord Zuko." Mai said, looking up to him with a smirk on her face.
As long as you're mine
