A scene from “Unfinished Business”

Daemon: I wasn't expecting you.

Rhaenyra: That seems rather a lapse in foresight. [looks around at the gathered army] I see you have done well here.

Daemon: They are sworn to me. And not a moment too soon.

Rhaenyra: And to whom are you sworn?

Daemon: [in High Valyrian] The world is not what we thought it was. This war is just the beginning. Winter is coming. And with it, darkness and doom.

Rhaenyra: [also in High Valyrian] You sound like my father.

Daemon: I saw it. I saw that we cannot withstand it. And yet, somehow, we must. [switches back to Common] The Realm's only hope is a leader that can unite it, and my brother chose you. [bends the knee] You are the true Queen. Rhaenyra, First of Her Name, Protector of the Realm. I am meant to serve you. And all of these with me, until death, or the end of our story.

[The entire army behind Daemon bends the knee]

Rhaenyra: [in High Valyrian] Leave me again at your peril.

Daemon: [rising] I could not. I have tried. My Queen. [turns and addresses the army] For every one of us who falls, a hundred of them! [draws his sword] There will be no mercy! We fight for our Queen!
