How did he get so terribly smart, so determined? Maybe it was the pain I'd caused that made him that way, and if that were true, then I'd sort of had a hand in it, in making him as smart and devious as he was. I was really starting to dislike the guy. But I also felt a little proud, like Dr. Frankenstein must have felt when his monster turned on him, because after all, it was Dr. Frankenstein who had made the monster strong and cunning enough to turn on him.
