If this is a joke, Zuko, it isn't a very appropriate or funny one. I think you've been hanging around Azula too much.

Don't be too hard on him, Dad, he just isn't used to me yet, give him some time, he'll come around.

Of course, given time, I'm sure he will.

[Yet there was something that nagged at him about what Zuko said, he didn't want to believe it... yet, no. This felt right]
