Haida stopped and glanced at the clock on the wall. Then he looked at Tsukuru. He was, of course, Haida the son, but Haida the father has been the same age in his story, and so the two of them began to overlap in Tsukuru's mind. It was an odd sensation, as if the two distinct temporalities had blended into one. Maybe it wasn't the father who had experienced this, but the son. Maybe Haida was just relating it as if his father had experienced it, when in reality he was the one who had. Tsukuru couldn't shake this illusion.
