Richard says nothing in reply, worry for his sister plain on his face. Once his sister is resting in the chair, he wanders around the office rifling through papers and cabinets looking for anything that could possibly be a manual relating to the x-ray machine. After about half an hour of searching, he finally found what he was looking for. An original manual for the machine. He let out a joyous shout and wandered back to the room where he left his sister. He waved the manual at her, and sat in a corner to read it.
