Yes!

[And here she takes a fast gulp, downing half the steaming mug at a go, reaching for her notes at the same time.]

I've been periodically measuring and questioning the passengers for a few months now, and I've observed no noticeable growth- not even from the juveniles, who should be experiencing osteogenesis at an accelerated rate. Lily, for example, she's been here for years, and she hasn't grown so much as an inch, and that's just not normal, especially for girls, as the average rate of increase is accelerated in early years, especially considering that she shows signs of semi-remote starvation periods, the compensation period is just way off. I'm not sure how he's doing it, though, since all the vital cellular processes are still operating normally- hair and nails keep growing, for example, and menstrual cycles continue, so it's safe to assume that internal things such as stomach linings are still replacing themselves at the normal rate, which is a good thing because otherwise the ulcerations would probably have killed us all, by now.

[She paused for breath and took another drink]

But that's not the thing that worries me.
