It wasn't long before Isabel could also hear the vibration, even far away from the rock, and she couldn't help but try to imagine what would cause such a sound of such volume and steadiness.  Even the wind could not do that, and she marveled anew at this strange 'technology'.<br/><br/>When she heard the clanging, she could not at first guess what it might be.  It was not the sound of armor, nor of weapons clashing, being a more delicate noise than either of those.  But it was certainly behind them, she decided, and slowed her pace to determine exactly where behind them.<br/><br/>She turned one direction, slowly, carefully aiming the light... and then the hand descended upon her opposite shoulder and she froze, realizing the depths of her failure.  "Doctor," she said, quietly, then bit back a cry as the hand's grip intensified.  "We have been found ourselves."<br/><br/>Her bow useless now, she let the arrow fall and concentrated on the light.  It was dazzlingly bright, especially to someone whose eyes were accustomed to the moonlight, and it might now be a better weapon in any case.  As quickly as she could, she turned the torch onto the face of her captor.<br/><br/>Turning herself enough to see the enemy was another matter as long as he had hold of her, but she did her best and caught a glimpse.  It was still a human face as far as she could see, with eyes, mouth, and nose, but beyond that at least part of it also reflected the beam in a way that should not have been possible for ordinary flesh.  The eyes did seem to squint against the glare, but it was far less of a reaction than she'd expected.<br/><br/>And worst of all, there was something familiar about the profile.  She had not seen him in years, but there was still something... "William?" she gasped, only barely managing to keep her grip on the torch as it threatened to fall from her hand.
