She had woken up again not in her own body, but her old own body. This was disappointing, but there was nothing to be done about it: the staff who remained their chronological age were doing what they could, and Nell had to simply wait. While this would not have been too great a problem at thirty, Nell was currently working with her twelve-year-old capacities which were decidedly less patient.

Feeling the same antsiness that had seen Nell a world-traveller instead of a wife and mother, the woman-turned-girl decided she simply must get some air. There were her duties to attend to, of course, though those that required more... physical presance than she had at present had already been delegated to one of her upper-year students. Nell made her way down to one of the courtyards.
It was there that she saw them.
Recognizing a face, when one was a professor, was hardly something to write home about. Indeed, it was rather part of the job. But this face sparked recognition not because of class or roving the halls or anything like that, but because the body it was attached to had been assigned a detention.
To serve at the staff table.
The night before many of the faculty had woken up as literal children.
"Oi!" she called out, voice still higher-pitched than Nell was useful, decidedly wrong. "You!"
There was a storm brewing in her dark eyes.
