She was allergic to cats, it was true (and why she kept a steady supply of allergy medication on her), but not pollen or grass. Part of her wondered if there was time to go back to get a few, but then thought better of it: she couldn't afford to be groggy at any point while off the train.

Not that any of this would stop her from trying to clear a path, of course.
