Comments of chapter undefined of Game of Thrones: Lord of the Seven Seas

Question. the druidic spells are a reward for changing future, but will there be still a reward for being on the winning side of the war (and having so much contribution for it), when the war (rebellion) ends officially? Another question is was Damian REALLY thinking about personally drinking the potion and becoming a giant, or he was more thinking about making an army of giant animals? Cus I dont think being a giant would have helped a lord in diplomacy with the other lords, not even mentioning not being able to go inside your own keep/castle.
