Mental fatigue.
Her whole stay was mentally taxing. Those around her have been people she didn't know and who have been hiding behind masks. There has been this psychological barrier between them all the time (Subject to experiments - isolation crew). They took samples of her and she had to yield. She had to stay in that room and they came and
left the room like they wanted. There has been a clean sub-conscious border been drawn between them. She was cut off from normal human interaction for weeks, leaving her to her memories about her kingdom and that feeling, she shouldn't stay in bed, but fight as a knight that invasion her nation has to face right now.
Also repeated tests aren't inhumane, but mentally taxing, too. Especially if they contain stuff you don't like, like giving urine samples or being pierced be a needle. (As far as I know, there is a technique to pierce the patient with a special needle once and leave it there for easy access later, so that you don't destroy those veins.)
Such a stay would be taxing for everyone and they couldn't have known, how it would fell for her. But they should have anticipated, because of her human form, that she might not react well to it. They have been so careful about the physical stuff, but couldn't spare a single psychologist/counselor to monitor her mental health? Even though they had good reason to theorize, that magic is invoked mentally, and they also have been looking for a possible magical illness?
I'm glad, that nurse called her superior on this, but I'm also mad at her, that it took that long. Maybe her job was on the line for doing so, but in this case it has been a shitty chain of commands.
As soon as she asked for the stat of her friend, the next thing you'd expect from the nurses is to think 'Maybe she want talk to her friends?' and inform mentioned superior about it. You'd expect them to care for her mental state, but they didn't. This situation was so far off a benevolent meant isolation and that mistake so obvious, that you have to draw the conclusion they might have done it on purpose. (Why? To remove her from sight for good? To test her behavior on slowly rising stress levels?)
I don't care if they provided "entertainment by other means" (a TV for example). She didn't make use of those, so they should have noticed that and try to counter that development. They didn't even really try to, or they would have allocated a person trained in psychological treatment from the start.
Verdict: -> Inhuman treatment (Either by device or incompetence)
We as the readers can judge this scenario on two levels:
Either we embrace it on a immersive level and in this case those fools of the government are either stupid or evil,
or we analyze it on the basis, that an author has written this and had to fit in drama. In that case that could have went better, as many readers have been pissed off about this. XD I for my part liked that excursion into semi-realism and would have enjoyed it more, if the author would have being a bit more realistic on the matter of mental care and a bit less focused on squeezing in that drama. That kind of "I missed you so much!" setting would have come in fruition anyways.
