A scene from “Unfinished Business”

Viserys: My father was a hale and healthy warrior and dragonrider at the peak of his abilities. Jaehaerys named a great royal hunt to celebrate him being named the Hand of the King. Five days later, my father lay dead. Tourneys last longer. Baelon the Brave, rider of Vhagar, heir to the Iron Throne, dead of a burst belly. The gods have a dark wit.

Otto: It was a grim day. I recall it all too well.

Viserys: It was a good day for you. Jaehaerys named you Hand in Baelon's stead.

Otto: That's hardly how I viewed it, Your Grace. It was a duty.

Viserys: You served my grandsire nobly in his final days. You are the man that taught me how to be King.

Otto: Oh, you honor me, Your Grace.

Viserys: Just five days you went from being another man in Jaehaerys's court to the second most powerful man in the realm. I wonder, how long did it take you to choose yourself over your King?

Otto: Your Grace?

Viserys: I will never recover from Aemma's death. But Alicent, she took me through the worst of my grief. She was a calculated distraction. I only now realize how well-calculated it was.

Otto: That is an absurdity. The Queen loves you as I know you love her.

Viserys: Your interests no longer align with those of the realm. Your judgment has been compromised.

Otto: A loyal Hand must tell his king a discomforting truth from time to time, Your Grace. If he doesn't, he's failed as a servant.

Viserys: You were a faithful servant, Otto. The Crown and the realm both owe you a debt that can never be repaid. But I can no longer trust your judgment.
