Well, my 2 cents on whose "Last Dying Breath" it me be is that I don"t think it will be an of the established characters to die. I think it is very possible that Saul and Victor will find someone in or around Ground Zero that has some info on what is going on and will give them a clue to what went on there with their last dying breath. Of course this is just me personal theory, I am probably wrong.
