A scene from “Unfinished Business”

Alicent: I do not wish to see you go.

Otto: Such is the king's decision.

Alicent: A decision I most vigorously regret.

Otto: And yet you made it possible. You chose Rhaenyra.

Alicent: She swore her innocence. And I believed her.

Otto: You wanted to believe her. As did her father.

Alicent: Your informant was wrong. An honest mistake, perhaps, but I did not foresee this!

Otto: You should have.

Alicent: If you had not been so relentless in advancing Aegon as heir...

Otto: Listen to me, daughter. The King will die. It may be months or years, but he'll not live to be an old man, and if Rhaenyra succeeds him, war will follow, do you understand? The realm will not accept her. And to secure her claim, she'll have to put your children to the sword. She'll have no choice. You know it. You're no fool and yet you choose not to see it. The time is coming, Alicent. Either you prepare Aegon to rule, or you cleave to Rhaenyra and pray for her mercy.
