The strange, tinny sound made Isabel wince, in equal parts fear and confusion.  Something about William -- if it was truly him in any real sense anymore -- made her realize that he, too, was afraid and confused, even panicked, but given his painful grip upon her shoulder this was not as reassuring as it might have been.  If he would not let go then she had no chance of breaking free.<br/><br/>"But what has become of him?" she whispered, utterly bewildered.  She turned to look at the Doctor, her dark eyes wide, and her hand trembled as she brought the torch closer to his outstretched hand.  "How can this be?"  Again her captor tried to make himself heard, and again there was only that desperate, wordless sound.  With little other choice, she obeyed the Doctor's words, though she could certainly not stop herself from shaking or her heart from racing.  The William she had known would never have hurt her, but the being next to her could hardly be the same person.
