Lord Frey spoke up to the crown prince, looking up from his plate of nuts he had been peeling with his fingers, “And what else do you offer my house, how are we to know you will honour your oath after Stark’s Greybeards cross?” He questioned, looking directly at Jace. Jacaerys knew what Lord Frey was implying, betrothal.

“You wish to install Frey blood on the throne?” Jacaerys asked, drinking the remainder of his wine, and allowing Lady Frey to refil his cup. “For that my mother will want for more than your crossing.” He smirked softly at himself, Yes he might have to marry a Frey girl and her blood will continue the Targaryen line but it was a small price to pay for his mother and his own inheritance.

Months later after Cregan Stark’s greybeards marched south over the twins- Jacaerys flew back to the twins on Vermax, hesitant, but he had an oath to fulfill, a promise to keep. A girl to wed.
