I on the other hand can see Howland coming into a scene, and then just as he is about to reveal R+L=J, he gets killed. It would be like Alderaan being destroyed all over again, as millions of fanboy voices suddenly cry out.
That's exactly what I've been thinking. Like a personification of Ned Stark's copy of Robert Baratheon's last will and testament. But instead of being torn up or burned (can't remember how Cersei destroyed it), he gets killed.
