You think it will actually happen this why? I feel like Ramsay is poised to make a move. Something is going to disrupt Stannis and I feel like Theon is either going to get away or his execution will be delayed. Let's not forget that Theon has a lot of valuable information about the Bolton's and their plans. He could still be useful. I think there's a possibility Theon may die but it's not definite. If Stannis is killed and Theon doesn't fall into the hands of Ramsay, what then?
