The door is, indeed, propped open - some of these cleansers still smell, and part of Nita wonders if that's just deliberate on the train's part - and Inigo's first shy response is enough to make her look up from where she's been scrubbing a peculiar stain.

"Of course! This tile's just being persistent in retaining the stain, for some reason-"

Then the rest of what he's saying hits him, and she stops scrubbing altogether.

"... You want to take a seat? Probably shouldn't close the door, though; the smell should be enough to keep people out."

This isn't her friend S'reee's cabin, so both lower bunks are present and comforter-ed.
