The only thing stopping him going to war is the fear of what would happen if he has to tell his banners, you know, be that Lord that breaks decades of peace only to have tens of thousands die. He has no official claim, but if he hears that Lord Crakenhall has made a bid for the Throne, then he will seek to depose them, and who knows who could become King if the Tyrells have no idea of who specifically they want. I still need to do Willas's CS, but dammit, I have so much shit going on :P  He'll emerge when it becomes relevant.
