(Spoilers Extended) Sweetrobin, flying and history

During Aegon's conquest, he didn't need to declare war on the vale, because Aegon's sister flew into the Eyrie and gave the current boy lord of the Vale a ride on the dragon. History repeating itself is a key theme in both book and show, and it seems likely that Dany could do this to persuade Sweetrobin to bring the Knights of the Vale to her over Jon Snow. Especially considering​ Sweetrobin's obsession with "flying" and how every chapter with him in, he screams about flying.
