A scene from “Unfinished Business”

Viserys: I wish I had known better what to say to you in the aftermath. I struggled to realize that my daughter had so quickly become a woman grown. But I know she understands what is now expected of me.

Rhaenyra: The king must take a new wife.

Viserys: I could never replace your mother. No more than I intend to replace you as heir. But you are my only heir and our line is vulnerable, too easily ended. And by marrying again, I may begin to ensure that we are better defended.

Rhaenyra: Against whom?

Viserys: Whomever may dare to challenge us. [pause] I do not wish to make us estranged.

Rhaenyra: You are the king. Your first duty is to the realm. Mother would have understood this. Just as I do.
