Rhaenyra sounded like an insane person when she brought up "the song of ice and fire" to Daemon. I wonder where her idea about that will go. Is this just a mere wink to GoT ? Or is there character-development surrounding this belief to be expected ? What will exactly happen to the false prophet ?
And that was also the moment that Daemon realizes that Viserys had never ever thought of him as his heir.
Though this entire "Song of Ice & Fire" stuff is just a 'show-only' thing as far as i can recall...
