On Robert’s Rebellion, considering that the implicit message of the pro-Aerys/Targaryen faction is that the King can burn people/Crown Prince can elope with another woman, why were the Tyrells so openly pro-Targaryen? Dorne had Elia, but after seeing Aerys at Whent’s tourney, and the precedent set by a victory, it doesn’t seem in their interest to concede that kind of royal power.
