I found I couldn't focus both my mind and my eyes through the electric flashes of agony, so I concentrated on Doc's voice and trusted my hands would follow their habit pattern and construct the symbols for his words. Beyond Six, Seven, Eight ... I remembered that he was somebody very important whose name and work I had once known, even if now I knew him only as Doc.
