Though she sensed that the Doctor's reply was deliberately cautious, Isabel did not question him more thoroughly on the subject.  Strangely, she did not mind assuming the worst and believing that there were indeed a whole host of enemy visitors nearby, but somehow<em>knowing</em>that was the case seemed more than she wanted to face at the moment.<br/><br/>She led the way for a few more steps in silence, searching for more marks despite knowing where they must lead.  Then she slowed her pace for a moment, convinced that they were being watched, though she was reluctant to raise the light to try to spot the watcher.  "Do you have a weapon, Doctor?" she asked, quietly, assuming the answer would be yes.  The future must have an amazing array of weaponry, after all, ones she could not imagine, and men of her time were rarely without something with which to defend themselves, even if it was only a knife.  "I am a fair shot, but I do not know if arrows will be of any use, however well-aimed."
