Great Dragon and Merlin in “The Beginning of the End”

The young warlock. No doubt you're here about the Druid boy.

How did you know?

Like you, I hear him speak.

Why does he call me Emrys?

Because that is your name.

I'm pretty sure my name's Merlin. It always has been.

You have many names.

Do I? How does the boy know who I am? I've never even met any druids.

There is much written about you that you have yet to read. You should not protect this boy.

Why? He has magic. He's just like me.

You and the boy are as different as day and night.
