"Trust me. If we were allowed to have rooms to ourselves, I would never leave mine."

Perhaps it's said with a touch of deadpan to her tone as she speaks, but Alice very much means that. She'd be more than happy to never have to socialize, especially with certain people on this train, thanks.

But she already knows the train doesn't care about them enough to actually provide them comfortable rooms. It's very much like the asylum in that sense.

"We are stuck with these four person rooms, regardless of how much we like it or not."
