Well, the train didn't have my interest before, you idiot. But it does now.
The sheer amount that the student council and staff were discouraging trips to find said spooky ghost train was the one and only thing that, to Isoroku, made it seem like there might be anything to the rumors. He did not, of course, expect that wishes were being granted. Was it possible that, in fact, there was something going on at the train station that the school did not want the students to know about? Something that could be used against them?
It was, Isoroku considered, utterly fascinating. He glanced sideways at Ishikawa, and very nearly smiled. He had several things to ask the boy, the moment Mori was gone.
None of that for now, though. Blank expression, blank expression.
