[Iroh shakes his head, how could that be possible?]

It might be a little strange, but it is possible, isn't it?

[His tone sounds a bit more unsure]

Of course it is possible, Zuko is just getting mad because he thinks I'll take his place. He doesn't see how good it will be, just like the old days.

That does make sense. Yes, don't worry Zuko. No matter what, you will always have a special place in my heart.
