You have to kill him. You must do it for your Queen and for the realm. You must put your heart aside to do what’s right. You must forget your love for him, even if for only a few hours.
He was your love, Aegon. Neither of you dared admit it, but you were inseparable as children. The two of you never kissed, never touched, he refused to taint you, despite how his heart yearned for you. You were a princess he could not have, so he stuck to his whores and wine growing up. All while he kept you as his dearest friend.
Now he’s usurped Queen Rhaenyra’s throne. You’ve always been quiet, overlooked, but ever skillful. In a cruel twist of fate, the Gods — or rather, Rhaenyra, had chosen you to kill the usurper.
It may well kill you with him, if you can do it.
