well I didn't want to give anything away, if you were comprehensive, then I assume you didn't read the books?
Season 3 of GOT did not cover all of the material in ASOS. They gave up on doing a season per book. Season 3 encompassed about 2/3 of ASOS and season 4 will likely finish ASOS and start digging into content from both AFFC and ADWD. We'll see what happens in season 5, but my guess is it will cover the rest of those two books and might even dip into the as yet unpublished book for new material on Dany's stalled-out Essos plotline. Surely they won't have her sit in Meereen for two entire seasons.
I want a dragon
"But I do know Joey's sister indirectly (or foster sister) and I have heard stories of Joey being into shopping, designer wear, fancy coffees, and pedicures."
I wouldn't keep them in a garage, I believe dragons do better free range. I'd dare anyone to try to sue me.
