That scene of Daenerys and the Unsullied is one of my favorites. Still gives me chills after so many watches. 😃
We had met Beric Dondarrion - the leader of the Brotherhood without banners - in season 1. If you remember that one time Ned was sitting on the throne while the king had gone hunting, and he ordered a knight to go capture and kill The Mountain and his men - they recast the actor playing the role so that might make it a bit harder to remember. In any case, you can think of the Brotherhood without banners now as a sort of Robin Hood band of outlaws. BTW, the "Red Priest" in that group is called Thoros of Myr and he follows the Lord of Light, same religion as Mellisandre.
