[It's tempting, to ask for accommodations to perhaps keep anyone else from vanishing. But at the same time, Masumi knows that the train likely won't accept that as a solution.]

...I don't want anyone else to leave for who knows where, and that would be a lot safer, but the train is already wary of the Ministry. I don't know if she'll accept being detained, since she was trying to avoid running into inspectors as much as possible. My worry is that she'll just keep avoiding the Ministry if anyone tries to stop her or the crew.

[That, and Masumi's still a bit wary of the Ministry, given she doesn't know much about them or how they might help.]
