Why did little kids keep showing up on this train? Conan seems the youngest so far. It was possible that his version of Hell was being responsible for all these kids on this train.

"Yoroshiku ne." He gives the child's hand a firm shake before letting go. "It seems to be a rite of passage on this train to accidentally open this stupid door." He's really glad he watched Peter do it, so he didn't have to do it himself. "I know a couple of teenagers who would be happy to help you put all of these back in the room if you need help." He wasn't about to do it.
