The queen smiles. "House [Your Name] was true to me when so many turned away. I will never forget [Lord/Lady] [Your Name]'s loyalty. Or yours."
Assure Daenerys you have your own reasons for going to Braavos. It's no judgment on her.
Tell Daenerys that she's won your heart with her compassion and strength.
"Her Grace will take Westeros in time," Ser Barristan says firmly. The queen quiets him. "Meereen needs me. I will not lose all I have gained with them."
"You have served me well, Olene," the queen murmurs. "Why leave now? Does your [lord/lady] no longer believe I can win back Westeros?"
Ask Daenerys to remember your service should she ever meet [Your Character].
Hesitantly ask why Daenerys is staying so long in Meereen instead of seeking her throne.
