"Nyall is a son of Tully blood," Ruvayn says fervently, "The traitor who murdered our king will never have legitimate rule in the Riverlands."
"True. Better any son of House Tully than Walder Frey. I will join you."
"How is Nyall better than Walder Frey?" "
Ruvayn Oridane comes to you at night. "My [lord/lady] [Your Last Name], you have been a friend to me. I am here to beg your support against Walder Frey."
"Go home and hope Walder Frey never learns of your folly. I will not rebel."
"What do you think Walder Frey will do to anyone rebelling against him?"
"He will have no mercy, I know that." Ruvayn looks very young, but resolute. "That is why we need the strength of [Your House] behind us!"
