What's the Lay of the Land?

The sense that coralus is big, mad and that this has been brewing kind of came out of left field for me, or at least came from the very first scene of this episode. I was glad to see things starting to starting to take shape in terms of what this season is going to be. It's not the same as feeling secure in it, because this is a show about the trgarians. Do we want the targarians to be in charge?
