Nic can sense Knights

Sanya and Michael slipped out of the stairwell. Sanya had his rifle in hand. They stood lookout while I bent down and pried open the dead gunman's mouth. He didn't have a tongue. "One of Nicodemus's boys," I said quietly.
"Something is wrong," Michael said. Blood dripped from the tip of the sword to the floor. "I don't feel him anymore."
"If you can feel him, can he feel you? Could he know if you were getting close to him?"
Michael shrugged. "It seems likely."
"He's cautious," I said, remembering how Nicodemus had reacted when Shiro came through the door. "He doesn't take chances. He wouldn't wait around to start a fight he wasn't sure he could win. He's running." I stood up and headed for the chapel. "Come on."
