That allowed me to watch Harry for the rest of the exam. He was hiding his pain as much as possible, but I could see it. At one point, he ended up putting his quill down and clamping the desk in a death grip. I tried to see if I could discern anything from his scar, but all I got was the usual dark sickly feeling I get when I focus too much on it. With that attempt coming up as a failure, I decided to ask him afterwards. He eventually returned to the exam and tried to continue as if nothing happened. But his eyes told a different story. He was also frantically writing on his exam.
